Description
The application be application No. is: 201610333315.7, the applying date: 2016-05-19, patent name " one kind have bubble
The divisional application of the patent of invention of the double-deck carbon fiber pipe and its manufacture craft of foam interlayer ".
Technical field
The present invention relates to carbon fiber fields, and in particular to a kind of double-deck carbon fiber pipe of novel foam interlayer.
Background technique
Carbon fibre composite is gradually universal to civil field from high-end fields such as aerospaces, and carbon fiber pipe has
The advantages that specific gravity is small, rigidity is big, intensity is high, corrosion-resistant is widely used in medical instrument, in sports equipment.But due to its own
Characteristic keeps the mechanical connection of carbon fiber pipe extremely difficult, so then being become using glue bonding, one kind is fairly simple efficiently to be connected
Connect mode.Nowadays, many steel construction pieces on automobile are just gradually replaced using carbon fiber product to mitigate weight.
The vehicle frame of truss-like automobile is formed by connecting by multiple tubing element, and traditional truss frame materials are mainly steel pipe or aluminium
Compo pipe, novel truss vehicle frame uses carbon fiber pipe now, but due between carbon fiber pipe connection and carbon fiber pipe
Connection with other parts is not available welding, using bonding or can only be bolted, but the intensity being bonded is smaller, and bolt
Connection can then destroy the carbon filament of carbon fiber pipe, make to be easy to happen fracture when its stress, in view of these situations, be used in the prior art
The carbon fiber pipe of truss vehicle frame is all to be bonded a metal joint at the both ends of carbon fiber tube body, then pass through metal joint and other
Carbon fiber pipe or part are attached.
The prior art is all first to make carbon fiber pipe, then the coating glue on metal joint, then by carbon fiber pipe and
Metal joint sticks together, and fabrication cycle is long.In order to facilitate connection, fit-up gap is often set between carbon fiber pipe and connector,
Result in the concentricity between carbon fiber pipe and connector bigger than normal in this way, and glue is in uneven thickness, if coating glue is excessive
Words, extra glue can also flow to connector for connection internal screw thread at and connector and carbon fiber pipe end face, glue curing
After be very difficult to handle, cause post-processing workload increase.When carbon fiber layer is Nian Jie with glue, connector modes of emplacement is usually
Horizontal positioned or vertical placement, due to the influence of gravity, glue is always unevenly distributed, and causes carbon fiber pipe Nian Jie with connector
Quality decline afterwards.
Existing carbon fiber pipe is all single layer, since the thickness of carbon cloth is smaller, carbon fiber pipe often wall thickness
It is smaller, noise and the no attenuation of vibration to automobile, so that the noise of truss-like automobile and vibration are larger.Carbon cloth
The area Nian Jie with connector is also smaller, and in order to improve adhesive strength, generally requires to lengthen the boss of connector, with increase its with
The area of carbon cloth contact, but the weight that will lead to carbon fiber pipe again in this way increases.

At, thus the lateral surface shape of internal model 8 can change according to the change in shape of its inside cavernous body 1, into the water by internal model 8
When cavernous body 1 softens after a certain period of time, the shape of internal model 8 can change, and cavernous body 1 can also be compressed.
The external mold 9 is removably formed by connecting by two semicircular cylinders, be can be and is distinguished in the side of two semicircular cylinders
Then setting flange is bolted, be also possible to bind two semicircular cylinders using snap ring.The external mold 9 by lateral surface to
Medial surface sets gradually shell 90, the first outer layer 91, the second outer layer 92, third outer layer 93, the shell 90, the first outer layer 91,
Second outer layer 92, third outer layer 93 constitute detachable connection between each other, can be between endothecium structure and layer structure
It is connected by way of interference fit, is also possible to endothecium structure and the mode of pin hole and pin is radially arranged in layer structure
Connection.
The shell 90, the first outer layer 91, the second outer layer 92, third outer layer 93 medial surface on anti-snearing is respectively coated
Layer；First outer layer 91, the second outer layer 92, third outer layer 93 shape respectively with outer layer carbon fiber pipe 1, froth bed 2, interior
The shape of layer carbon fiber pipe 3 is adapted.
The manufacture craft of the double-deck carbon fiber pipe is the following steps are included: interior mold forming, carbon fiber pipe molding, carbon fiber
Pipe post-processing.
Internal model forming step as shown in Figures 2 to 7, described are as follows: by the both ends of external mold 9 respectively with a metal joint
4 connections, make the medial surface of third outer layer 93 and the outside face contact of third dome platform 71, the end face of third outer layer 93 and second close
The upper surface of seal 62 is adjacent to, and internal model 8 is immersed in the water a period of time, so that cavernous body 81 is softened, internal model 8 is then penetrated two
In the cavity region of metal joint 4 and external mold 9；Bindless dry sand powder, glue are successively poured into the cavernous body 81 of internal model 8
Water, then dry internal model 8, make cavernous body 81 expand, after a certain period of time when glue it is Nian Jie with dry sand solidify and cavernous body 81 hardening,
External mold 9 is removed, and third outer layer 93 is removed from external mold 9.
The carbon fiber pipe forming step include the molding of internal layer carbon fiber pipe, foam formable layer, outer layer carbon fiber pipe at
Type；
The internal layer carbon fiber pipe forming step are as follows: carbon cloth is successively wrapped in internal model 8, third dome platform 71
On lateral surface；Then the external mold 9 for having removed third outer layer 93 is mounted on to the outside of carbon cloth, the end face of the second outer layer 92 with
The upper surface of second sealing ring 62 is close to, while the medial surface of the second outer layer 92 is close to the lateral surface of carbon cloth；Then to
Epoxy resin, the third permeability hole on the metal joint 4 of the other end are poured into third permeability hole 73 on the metal joint 4 of one end
73 are successively connect with knockout drum, vacuum pump by vacuum tube；Start vacuum pump, driving motor 12, to the second outer layer 92, internal model 8,
The region that second sealing ring 62 surrounds, which vacuumizes simultaneously pressure maintaining, for a period of time, makes epoxy resin be evenly arranged on internal model 8, third dome platform 71
On carbon cloth on lateral wall, while carbon cloth is in rotation status always, makes being more evenly distributed for epoxy resin.Due to
