Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the internal cross section structural representation of the composite product of the preferred embodiment of the present invention;
Fig. 2 is the Facad structure schematic diagram of the stay pipe of the preferred embodiment of the present invention; And
Fig. 3 be the stay pipe of the preferred embodiment of the present invention partly cut open structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 1, according to an aspect of the present invention, provide a kind of composite product, comprising: many support rib frame member 10, these support rib frame member 10 are according to the arrangements of composite product; Braided fiber 30, forms the prefabricated component with the mating shapes of composite product jointly with these support rib frame member 10 between the outer surface being arranged in support rib frame member 10 layer by layer; Cast matrix 50, to impregnated in prefabricated component and be integrally formed composite product with prefabricated component after solidification.
Adopt many support rib frame member 10 as support and shaped structure in composite product provided by the invention, braided fiber 30 is arranged layer by layer again at the outer surface finger tip of support rib frame member 10, the interlaminar shear strength of composite product can be made to strengthen, overcome composite product be hit after yielding defect, improve the reliability of composite product.
Support rib frame member 10 can adopt the middle stay pipe for hollow structure, because this stay pipe serves the guide effect to establishment fiber 30 simultaneously, also can be called guide support pipe.Further, in order to make the dipping effect of composite material prefabricated component better, the tube wall of every root stay pipe is provided with multiple communication through-holes 11 for making liquid cast matrix 50 circulate.In actual braiding process, should note avoiding communication through-holes 11 to block as far as possible.
As shown in Figures 2 and 3, guide support pipe is hollow structure, the shape of composite product prepared by the interior shape of this guide support pipe and outer shape and needs adapts, alternatively the interior shape of guide support pipe and the shape and structure of outer shape composite product as required and different.The tube wall of guide support pipe is arranged through communication through-holes 11, the shape of communication through-holes 11 is any.The position of guide support pipe in composite product and angle are also different from the shape of composite product and performance requirement, the outer shape of guide support pipe can be column tube, also can be conical pipe, its interior shape can be also can be taper or cylindricality, can also be corrugated etc.
According to the performance requirement of the composite product that will manufacture, the cast matrix 50 that impregnated in prefabricated component can be the one in the matrixes such as resin-based, Metal Substrate or ceramic base.These materials are known materials, wherein, resin-based is also called high polymer base, and high polymer base can divide again thermosetting high polymers base (as epoxy resin, unsaturated polyester (UP) and polyimides etc.) and thermal plasticity high polymer base (as various general plastic and polyethers phenol, the contour performance kind of polyphenylene sulfide).High polymer (resin) matrix is applied very extensive in the composite, its technical maturity, and especially thermosetting high polymers uses history long, but generally can only use below 300 DEG C.What metallic matrix was conventional has Al, Mg, Ti etc., and high temperature alloy and refractory metal are also in trying out.Their serviceability temperature scope is 400 to 1100 DEG C, but technique is still immature.Glass-based, ceramic base etc. can also be adopted as cast matrix 50.
According to another aspect of the present invention, additionally provide a kind of composite product manufacturing process, the method comprises the steps:
The first, according to the position of the arrangements many support rib frame member of composite product;
The second, braided fiber layer by layer between the outer surface of support rib frame member, make braided fiber and its is jointly formed and the prefabricated component of mating shapes of composite product;
3rd, dipping cast matrix in prefabricated component also makes the solidification of cast matrix be integrally formed composite product with prefabricated component.
Specifically, support rib frame member is the stay pipe of hollow.
Before the position of the arrangements many support rib frame member according to composite product, the sidewall being also included in every root support rib frame member offers multiple communication through-holes that matrix is circulated.Close in the pass of stay pipe and offer multiple communication through-holes.Fiber near dipping stay pipe, and spread to export-oriented depths thus, form inside and outside integrity dipping.
According to the shape of the composite product that will manufacture, the difference of intensity, the size of communication through-holes 11, shape and quantity are indefinite, as long as can meet the intensity of composite product and can be good at realizing the dipping of cast matrix 50.
In prefabricated component, liquid forming technology can be adopted to enter to be injected in prefabricated component by class matrixes such as resins during dipping cast matrix.
Composite product provided by the invention and manufacturing process thereof, a prefabricated component that the is overall and mating shapes of composite material prefabricated component to be processed is become with braided fiber Co-knit and dip forming by stay pipe, avoid the defects such as stress deformation, add composite interlayer shear strength and resistance to compression and bending strength, improve the overall density of composite product, and then rigidity and reliability also improve, adapt to the demand of the main force support structure such as Aero-Space and defence and military part.
In addition, composite product provided by the invention and manufacturing process thereof arrange multiple communication through-holes that cast matrix is circulated on the tube wall of stay pipe, when matrix is after injection porous guide support pipe, permeated by the interior of communication through-holes by porous tubular support, fiber near dipping stay pipe, and spread to export-oriented depths thus, form inside and outside integrity dipping.The micropore of stay pipe tube wall adds resin flow channel, promotes resin flows speed, shortens the composite material forming time, enhance productivity; Cast matrix flows can be made even, and the fiber in prefabricated component depths also can be impregnated into by matrix equably simultaneously, avoids the appearance that leaching is saturating, flood the defects such as uneven and dry spot, improves impregnating effect.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
