Description

Filament winding apparatus and filament winding method TECHNICAL FIELD OF THE INVENTION

The present invention relates to a filament winding device and a filament winding method, and more particularly, to impregnate different types of resins by crossing each other according to the direction or length of the fibers wound on the liner. By selecting any one of the resin supply parts containing the resin and winding the fibers impregnated with resins having different elongation, stiffness and heat resistance to manufacture the pressure vessel, the pressure vessel containing the high-pressure gas is prevented from cracking while maintaining heat resistance and stiffness. It relates to a filament winding device and a filament winding method that can be increased at the same time.

There are several methods of molding composite materials, and the molding methods for composite materials based on polymer materials include autoclave molding, vacuum bag molding, compression molding, and filament. There are Filament Winding, SMC molding method (Sheet Molding Compound) or BMC molding method (Bulk Molding Compound), RTM molding method (Resin Transfer Molding), pultrusion molding method (Pultrusion), heat press molding method, etc. Among these methods, filament winding molding is a method mainly used for manufacturing circular products.

The filament winding method is a composite molding method in which continuous fibers impregnated with resin are wound around a cylindrical rotating mold (Mandrel) and then cured to produce a rotationally symmetrical structure. Resin Bath) and impregnated wet winding method and dry winding method using toe prepreg are applicable.

Among these, in the case of the wet winding method, the fiber impregnated with resin is wound on the liner. The amount of resin impregnated in the fiber varies greatly due to the viscosity of the resin, the tension of the fiber, and the pressure of the impregnating roll. It becomes a factor that influences the quality of the product.

In recent years, the development of hydrogen fuel cell vehicles as a next-generation vehicle has been actively developed, and hydrogen fuel cell vehicles are eco-friendly vehicles that operate by driving a motor using electricity obtained by reacting hydrogen and oxygen in the air instead of a gasoline internal combustion engine. Hydrogen fuel cell vehicles rarely emit pollutants, so environmental pollution is low, and long distance driving is possible with a small amount of fuel. However, in the event of a severe vehicle accident, there is a possibility that hydrogen may explode, and the economy is pointed out as a disadvantage due to the high energy consumption in generating hydrogen. The generation of electricity, which is the core of a hydrogen fuel cell vehicle, drives a motor with electricity generated by reacting hydrogen and oxygen through a catalyst. In other words, when water is electrolyzed, oxygen is generated at the positive (+) electrode and hydrogen is generated at the negative (-) electrode. If you reverse this and use hydrogen to create water, electricity is generated in the process. The most efficient method of storing hydrogen, which is the core of such a hydrogen fuel cell vehicle, is a method of storing hydrogen at high pressure in a hydrogen tank. This is a method of supplying hydrogen using a compressed hydrogen tank/liquid hydrogen tank, and it is completely pollution-free because only water is generated during operation. However, the increase in vehicle volume due to the mounting of the tank, the instability of hydrogen, and the difficulty of establishing the hydrogen supply infrastructure are disadvantages.

Pressure vessels for storing high-pressure gas basically require a material that is strong and withstands high pressure. In particular, in the case of pressure vessels used in automobiles, it is essential to reduce the weight of the structure in order to improve fuel efficiency and performance of automobiles. Therefore, the application of a light and strong carbon fiber composite material is an effective solution to replace the pressure vessel made of metal. Composite pressure vessels such as hydrogen tanks and compressed natural gas (CNG) tanks are generally manufactured using a filament sinding method, which is manufactured by impregnating carbon fiber with epoxy resin and then winding it on a plastic liner. This is because a cylindrical structure or a structure having a curvature can be easily manufactured by integral molding.

In addition, the filling pressure of the hydrogen tank is 350 bar or 700 bar, and in order to prevent accidents due to instability of hydrogen, it is regulated to verify the stability with a pressure of 1.5 times when manufacturing the container.

1 and 2, the types of methods of winding resin-impregnated fibers on a plastic liner in order to manufacture a pressure vessel such as a hydrogen tank are Hoop Wrapped (Vertical Winding) and Helical Wrapped (Helix). Winding), Hoop Wrapped (Vertical Winding) is used as a method to increase elongation, and Helical Wrapped (helical winding) is used for strength.

Referring to FIG. 3, since the pressure vessel manufactured by the conventional filament winding device and the filament winding method is manufactured by winding a plastic liner using fibers impregnated with a single resin having the same elongation, the manufactured pressure When the container is filled with gas or an internal pressure test is performed, the gas container expands. In this case, the degree of expansion is different between the cylinder direction (A direction) and the circumferential direction (B direction) of the pressure container, so that the degree of expansion is relatively large. In the direction (direction B), cracks (C) occur, which deteriorates the performance and stability of the pressure vessel.

In addition, in the conventional filament winding device and the pressure vessel manufactured by the filament winding method, the gas vessel expands during the process of filling gas or performing an internal pressure test into the manufactured pressure vessel, causing cracks in the circumferential direction (B direction). Since the pressure vessel is used by the operator or the driver of a hydrogen fuel cell vehicle in the state in which it has occurred, it causes inconvenience to the experimenter conducting the internal pressure test due to the explosion of hydrogen gas, etc., which has very high explosive power, and property accidents such as automobiles or personal accidents. There was a problem with a very high risk of a safety accident.

Besides. Conventional filament winding devices and pressure vessels manufactured by the filament winding method are frequently damaged during gas filling or internal pressure testing, and thus have low durability, so the pressure vessel, which is the test material, must be frequently replaced during the internal pressure test. There is a problem of delaying the time, and when it is installed and used in a vehicle, there is a problem in that the maintenance cost of a vehicle, etc. has to be greatly increased, such as having to replace the pressure vessel or the vehicle itself for stability.

For example, when tension is to be applied to the fiber (2) impregnated with the resins (4, 5), the sub-adjustment part 2222 is raised and lowered so that the resins 4 and 5 are moved between the main adjusting part 2221. By pulling the impregnated fiber (2) more strongly, the tension of the fiber (2) impregnated with the resin (4, 5) is applied, and the tension must be subtracted to the fiber (2) impregnated with the resin (4, 5). In this case, the sub-adjustment part 2222 is lowered and the resin (4, 5) is impregnated by weakly releasing the force that pulled the fiber (2) impregnated with the resin (4, 5) between the main control part (2221). It is possible to reduce the tension of the fiber (2).

The separation unit 2500 of the injection unit 5000 allows the fibers 2 impregnated with resins 4 and 5 to be drawn out of the injection unit 2000 through the resin supply unit 2300 and the resin selection unit 2400. It is formed in the shape of a comb so that the fibers 2 are not mixed before it plays a role of organizing the fibers 2.

That is, the resin selection unit 2400 selects one of the first resin supply unit 2310 or the second resin supply unit 2320 so that the fibers 2 are accommodated in the bath of the first resin supply unit 2310 It serves to impregnate only one of the different types of resin accommodated in the bath portion of the second resin supply unit 2320.

The resin selection unit 2400 is provided in the first resin supply unit 2310 and the second resin supply unit 2320 in order to cross and impregnate different types of resins according to the direction or length of the fibers 2 wound around the liner 3. When different types of resins (4, 5) are accommodated, and the rod portion (2413) adjacent to the first resin supply portion (2310) is introduced according to the direction or length of the fibers (2) wound on the liner (3). 2 When the rod portion adjacent to the resin supply portion is drawn out and the rod portion adjacent to the first resin supply portion is drawn out, the rod portion adjacent to the second resin supply portion is drawn in.

The resin selection unit 2400 includes a fiber moving unit 2410 and a bath moving unit 2420. The fiber moving part 2410 is accommodated in the bath part of the first resin supply part 2310 by adjusting the position where the fiber 2 is transferred to be wound on the liner, and is accommodated in the bath part of the resin or the second resin supply part 2320.

The injection unit 2000 of the filament winding device 1 according to the present invention is characterized in that different types of resins 4 and 5 are intersected and impregnated according to the direction or length of the fibers 2 wound on the liner 3. It is done.

When manufacturing pressure vessels such as hydrogen tanks and compressed natural gas (CNG) tanks through filament winding equipment, one of the resins used is epoxy resin, which is characterized by mechanical properties, heat resistance, and chemical resistance. Because it is excellent, it is suitable for pressure vessels where safety certification is essential. In addition, urethane resins, as other types of resins, have excellent elongation and chemical resistance, but have low heat resistance, and phenolic resins have high chemical resistance and heat resistance, but high viscosity, and thus are not suitable for performing a wet winding process.

The filament winding device 1 according to the present invention includes a resin 4 accommodated in the bath part 2341 of the first resin supply part 2310 and the resin 5 accommodated in the bath part 2341 of the second resin supply part 2320. Is formed of different types of resins.

Specifically, the resin 4 accommodated in the bath part 2341 of the first resin supply part 2310 uses a resin having a high elongation, and the resin 5 accommodated in the bath part 2341 of the second resin supply part 2320 has an elongation rate. Use this low resin. Alternatively, on the contrary, the resin 4 accommodated in the bath part 2341 of the first resin supply part 2310 uses a resin having a low elongation, and the resin 5 accommodated in the bath part 2341 of the second resin supply part 2320 is Use a resin with high elongation

The elongation refers to the rate at which the material is stretched during the tensile test of the material.In the present invention, two resins with a high elongation and a low resin are used. In order to prevent cracks from occurring in the circumferential direction, fibers impregnated with a high-elongation resin are used for winding, and fibers impregnated with a resin with low elongation are impregnated to maintain the high stiffness of the pressure vessel itself filled with high-pressure gas. The high-elongation resin is impregnated with fibers and is used at intersections to wind the liner.

Resins with high elongation have the advantage of being flexibly elongated due to the expansion of the pressure vessel due to their high elongation rate, but resins with high elongation have a problem of insufficient heat resistance due to low Tg values. On the contrary, resins with low elongation have advantages of high heat resistance and rigidity. Due to the low elongation ability, a problem occurs in that the pressure vessel is cracked due to the expansion of the pressure vessel.

Therefore, in the filament winding device 1 according to the present invention, the resin 4 accommodated in the bath part 2341 of the first resin supply part 2310 uses a resin having high elongation, and the bath part of the second resin supply part 2320 ( The resin 5 accommodated in the 2341) uses a resin having a low elongation or, on the contrary, the resin 4 accommodated in the bath portion 2341 of the first resin supply unit 2310 uses a resin having a low elongation rate, and the second resin supply unit ( The resin 5 accommodated in the bath portion 2341 of 2320) can complement both heat resistance performance and elongation by using a resin having a high elongation and crossing it with a resin having a low elongation.

One of the different types of resins 4 and 5 accommodated in the bath portion 2341 of the resin supply unit 2300 of the filament winding device 1 according to the present invention, the resin having a low elongation has an elongation of 1% or more to 3 % Or less, and the other of the different types of resins 4 and 5, the resin having a high elongation may have an elongation of 5% or more and 10% or less.

If the elongation of the resin with low elongation, which is one of the different resins (4, 5), is less than 1%, the degree of elongation of the fiber is too small to break due to the tension applied to the fiber during the winding process. If the elongation exceeds 3%, the heat resistance is too low to comply with the verification items of the pressure vessel, and the rigidity is too low, causing a risk of explosion such as hydrogen in the pressure vessel.

In addition, if the elongation of the resin with high elongation, which is one of the different types of resins (4, 5), is less than 5%, the degree of stretching of the fibers is too small, so gas in the pressure vessel manufactured by the filament winding device and the filament winding method. The gas container expands when the gas is filled or the pressure test is performed. In this case, the degree of expansion is different between the cylinder direction (A direction) and the circumferential direction (B direction) of the pressure container, and the degree of expansion is relatively large in the circumferential direction (B Direction) so that the fibers cannot be stretched to correspond to the degree of expansion in the direction), and a crack (C) occurs in the circumferential direction (B direction) of the pressure vessel, resulting in a problem of deteriorating the performance and stability of the pressure vessel. In addition, when the elongation exceeds 10%, there is too much fiber to be swamped, and the force to press the liner against the tension of the fiber is too small due to the fiber winding around the liner 3, so the stiffness of the compression container containing the compressed gas is too low. As it is low, not only does not comply with the verification items of the pressure container, but also has a problem that the stiffness is too low, causing an explosion risk such as hydrogen in the pressure container.

As described above, the resin having a low elongation, which is any one of the heterogeneous resins 4 and 5 accommodated in the bath portion 2341 of the resin supply unit 2300, has an elongation of 1% or more and 3% or less. The other of the resins (4, 5), which is one of the resins with high elongation, has an elongation of 5% or more and 10% or less, and when two resins with a high elongation and a low resin are used interchangeably by the resin selector described below When the pressure vessel is filled with hydrogen by winding it using fibers impregnated with a high elongation resin, the vessel expands to prevent cracks from occurring in the circumferential direction of the pressure vessel, and fibers impregnated with a low elongation resin are used. By using the winding as a gyoza, the pressure vessel itself is filled with high-pressure gas and maintains the high rigidity of the pressure vessel itself to increase the stability of the pressure vessel itself. It can prevent safety accidents.

The filament winding device 1 according to the present invention combines the above-described resins with high elongation or different types of resins 4 and 5, which are resins with low elongation, depending on the direction or length of the fibers 2 wound on the liner 3 Cross and impregnate.

Referring to FIG. 5 for example, when the direction of the fiber 2 wound on the liner 3 is a hoop wrapped (vertical winding), the front end of the arm 4300 of the carriage unit 4000 As the winding part 4400 is positioned in the height direction, a hoop wrapped (vertical winding) is performed as shown in Fig. 1. The hoop wrapped (vertical winding) is used as a method to increase the elongation. It should be wound using a fiber (2) impregnated with a resin having a high elongation.

If a resin 4 having a high elongation rate is accommodated in the first resin supply unit 2310 and a resin 5 having a low elongation rate is accommodated in the second resin supply unit 2320, the upper portion of the first resin supply unit 2310 The rod part 2413 of the cylinder part 2412 installed facing the side is pulled out, and the rod part 2413 is pulled out adjacent to the first resin supply part 2310 and sandwiched between the rolling parts 2414. (2) In addition, it moves in a direction adjacent to the first resin supply unit 2310 so that the fibers 2 come into contact with the drum unit 2341 of the first resin supply unit 2310, and the elongation received in the first resin supply unit 2310 As the high resin 4 moves along the drum portion 2341 and comes into contact with the fibers 2, the resin 4 having a high elongation rate is impregnated with the fibers 2.

In addition, at the same time, since the drum portion 2341 and the fiber 2 of the second resin supply unit 2320 in which the resin 5 having a low elongation is accommodated should not be in contact, the upper portion of the second resin supply unit 2320 is faced. The rod part 2413 of the installed cylinder part 2412 is pulled in, and the rod part 2413 is pulled away from the second resin supply part 2320, and the fiber 2 sandwiched between the rolling parts 2414 In addition, it moves in a direction away from the second resin supply unit 2320 so that the fibers 2 do not come into contact with the drum unit 2341 of the second resin supply unit 2320, so that the resin with a low elongation is accommodated in the second resin supply unit 2320. (5) prevents impregnation into the fiber (2).

Referring to FIG. 6, an example in the opposite case to that of FIG. 5 will be described, when the direction of the fiber 2 wound around the liner 3 is a helical wrap as shown in FIG. 2, a carriage unit ( When the winding part 4400 is rotated and inclined at the tip of the arm part 4300 of 4000) instead of being positioned in the height direction, a helical wrapped (helical winding) is performed as shown in FIG. 2. Helical Wrapped (helical wrap) is used to increase the strength, and in this case, it must be wound using a fiber (2) impregnated with a resin with a low elongation.

If a resin 4 having a high elongation rate is accommodated in the first resin supply unit 2310 and a resin 5 having a low elongation rate is accommodated in the second resin supply unit 2320, the upper portion of the second resin supply unit 2320 The rod part 2413 of the cylinder part 2412 installed facing the side is pulled out, and the rod part 2413 is pulled out adjacent to the second resin supply part 2320 and sandwiched between the rolling parts 2414. (2) In addition, by moving in a direction adjacent to the second resin supply unit 2320, the fibers 2 come into contact with the drum unit 2341 of the second resin supply unit 2320, and the elongation received in the second resin supply unit 2320 As the low resin 5 moves along the drum portion 2341 and comes into contact with the fibers 2, the resin 5 having a low elongation rate is impregnated with the fibers 2.

In addition, at the same time, the drum portion 2341 and the fiber 2 of the first resin supply unit 2310 in which the resin 4 having high elongation is accommodated should not be in contact with each other so that they face the upper portion of the first resin supply unit 2310. The rod part 2413 of the installed cylinder part 2412 is pulled in, and the rod part 2413 is pulled away from the first resin supply part 2310, and the fiber 2 sandwiched between the rolling parts 2414 In addition, it moves in a direction away from the first resin supply unit 2310 so that the fibers 2 do not come into contact with the drum unit 2341 of the first resin supply unit 2310, so that the resin having a high elongation is accommodated in the first resin supply unit 2310. (4) prevents impregnation into the fiber (2).

In addition, the filament winding device according to the present invention can perform the above-described operation according to the length of the fiber 2 wound on the liner 3, for example, the length of the fiber 2 wound on the liner 3 If is less than a certain length, the operation as shown in FIG. 5 is implemented, and thereafter, in a manner of implementing the operation as shown in FIG. 6, different types of resins 4 and 5, which are resins with high elongation or low elongation, are intersected with (2) can be impregnated.

As described above, the filament winding device according to the invention produces a pressure vessel through fibers impregnated with resins having different elongation depending on the direction of the fibers wound on the liner or the length of the fibers. In the process, in order to increase the elongation in the circumferential direction (direction B), which has a relatively large degree of expansion, the fiber is wound through the fiber impregnated with a resin having a high elongation in the circumferential direction (direction B) to cause cracks in the pressure vessel It is possible to increase the durability and stability of the pressure container by preventing it from occurring, and it is possible to prevent the occurrence of cracks (C) in the circumferential direction (B direction) due to the expansion of the gas container during the process of filling gas or performing an internal pressure test. Because it is prevented in advance, accidents on property such as explosions of automobiles in which pressure vessels are stored by safe storage of hydrogen, etc. with very high explosive power, or personal accidents including workers who perform internal pressure tests or charge gas or drivers of hydrogen fuel cell vehicles, etc. It can prevent safety accidents.

The resin selection unit 2400 according to the present invention includes a bath moving unit 2420. It includes a bath moving part 2420, a support part 2421, a housing part 2422, an elevating part 2423, and a detection part 2424.

The support part 2421 is installed adjacent to the resin supply part 2300 and serves to support the resin supply part. The support part 2421 may be installed so as to be spaced apart from the support part 2411 while facing each other in the height direction.

The housing part 2422 may be formed in plural, and each housing part 2422 is installed between the lower part of the first resin supply part and the upper part of the support part 2421, and the lower part of the second resin supply part and the support part 2421 It is installed between the upper part of ).

The elevating part 2423 is installed in the housing part 2422 so as to be retractable or withdrawn.

The detection part 2424 is installed in the housing part 2422 to detect the operation of the bath moving part 2420.

The bath moving part 2420 accommodates different types of resins in the first resin supply unit and the second resin supply unit, respectively, in order to impregnate different types of resins by crossing each other according to the direction or length of the fibers wound on the liner. When the elevating portion adjacent to the first resin supply portion is drawn in (lowered) according to the direction or length of the fiber to be wound, the elevating portion adjacent to the second resin supply portion is drawn (elevated) and adjacent to the first resin supply portion. When the elevating portion is drawn out, the elevating portion adjacent to the second resin supply portion is drawn in.

Referring to FIG. 7 for example, when the direction of the fiber 2 wound around the liner 3 as in FIG. 5 is a hoop wrapped (vertical winding), the arm 4300 of the carriage unit 4000 ), as the winding part 4400 is positioned in the height direction, as shown in Fig. 1, hoop wrapped (vertical winding) is performed.Hoop Wrapped (vertical winding) is used as a method to increase elongation. In this case, it must be wound using a fiber (2) impregnated with a resin having a high elongation.

In this case, the fiber moving part 2410 operates as described above, and the bath moving part 2420 also operates at the same time as the operation of the fiber moving part 2410. If a resin 4 having a high elongation rate is accommodated in the first resin supply unit 2310 and a resin 5 having a low elongation rate is accommodated in the second resin supply unit 2320, the lower portion of the first resin supply unit 2310 The elevating portion 2423 of the housing portion installed in the housing portion 2423 is pulled out (raised) and pushed while pressing the first resin supply portion 2310 so that the first resin supply portion 2310 is raised to be adjacent to the fiber 2. Accordingly, when the fibers come into contact with the drum portion 2341 of the first resin supply portion 2310, the resin 4 having high elongation accommodated in the first resin supply portion 2310 moves along the drum portion 2341 to move the fibers 2 ) And the resin (4) having a high elongation rate is impregnated into the fibers (2) as they come into contact with each other.

In addition, at the same time, since the drum part 2341 of the second resin supply part 2320 and the fiber 2 in which the resin 5 having low elongation is accommodated should not be in contact, the housing installed under the second resin supply part 2320 The negative elevating portion 2423 is input (lowered) so that the second resin supply portion 2320 is lowered so as to move away from the fiber 2 while lowering. Accordingly, the fibers do not come into contact with the drum portion 2341 of the second resin supply unit 2320 so that the resin 5 having a low elongation received in the second resin supply unit 2320 is prevented from being impregnated into the fiber 2.

Referring to FIG. 8, an example in the opposite case to that of FIG. 7 will be described, when the direction of the fiber 2 wound around the liner 3 is a helical wrap as shown in FIG. 2, a carriage unit ( When the winding part 4400 is rotated and inclined at the tip of the arm part 4300 of 4000) instead of being positioned in the height direction, a helical wrapped (helical winding) is performed as shown in FIG. 2. Helical Wrapped (helical wrap) is used to increase the strength, and in this case, it must be wound using a fiber (2) impregnated with a resin with a low elongation. Therefore, the operation is reversed from the case of FIG. 7 described above.

In addition, the filament winding device according to the present invention can perform the above-described operation according to the length of the fiber 2 wound on the liner 3, for example, the length of the fiber 2 wound on the liner 3 When is less than a certain length, the operation as shown in FIG. 7 is implemented, and thereafter, in a manner of implementing the operation as shown in FIG. 8, different types of resins (4, 5), which are resins with high elongation or resins with low elongation, are intersected with each other. (2) can be impregnated.

As described above, the filament winding device according to the invention provides a method of impregnating resins having different elongation depending on the direction of the fibers wound on the liner or the length of the fibers by crossing and impregnating not only the above-described fiber moving unit but also the bath moving unit. As the fiber descends by the eastern part, the bath part is raised and lowered by the bath moving part, and in the opposite case, the opposite operation is implemented at the same time, so that the drum part with the selected resin among the different types of resins and the fiber come into contact with each other easily and precisely. Filament winding operation by impregnating the resin with different elongation depending on the direction of the fiber wound on the liner or the length of the fiber by impregnating it with the rest of the resin so that the remaining resin is not impregnated. Time can be minimized.

In addition, the filament winding device according to the present invention describes a method of impregnating resins having different elongation depending on the direction of the fibers wound on the liner or the length of the fibers. Regardless, it is implemented by the operation of the bath moving part, where only the bath moves, and minimizes damage to the fiber due to tension caused by the operation of the excessive fiber moving part during the fiber winding process, and the fiber tension is changed frequently. It is possible to increase the durability and stability of the pressure vessel by preventing the production of defective pressure vessels because the impregnation rate of impregnation cannot be uniform due to the change of the tension of the pressure vessel.
