Abstract
A mixing and forming method of a carbon fiber composite material. The method is as below: firstly, forming carbon fiber saturated resin into yarn sheets to prepare a composite material product preform; at the same time, preparing a silicone core shaft; secondly, embedding an airbag into a straight tube position of the preform to form a loop triangle position; then installing the silicone core shaft in a special pipe of the preform; furthermore, placing the preform in a forming die, pressurizing and heating the die while heating and pressurizing the air bag; finally, opening the die, cooling the moulded composite product, removing the air bag and the silicone core shaft, so as to complete moulding of a composite product with specific special-shaped part. The method of the invention uses the characteristics of expend with heat and contraction with cold and easy deformation of silicone core shaft, which is filled the special-shaped position of the composite material for moulding of the composite product, can achieve integral moulding of composite product with special-shaped part, make the moulding of composite product more simple and practical, and can ensure the integrity of the strength and appearance of the pipe fittings; in addition, the silicone core shaft can be used repeatedly to further reduce the manufacturing cost of the composite product.
Description
Technical field
The invention relates to a kind of carbon fibre composite mixed-forming method, belong to material technology field.
Background technology
Continuous progress along with science and technology, carbon fibre composite (multiple material) has been not limited to aerospace use, various carbon fiber composite material articles have also entered in mediocrity's life, littlely to racket, do not see nowhere the figure of carbon fibre composite greatly to automobile.The intensity of carbon fibre composite is higher than copper, and own wt is but less than aluminium, compares with glass fibre, and carbon fiber also has the feature of high strength, high-modulus, is very excellent enhancement mode material, can apply as novel nonmetallic materials.
Current common pipe fitting carbon fiber composite material article, for example cycle frame, is by each straight pipe independent preformed respectively of vehicle frame, then splices at abnormity place, and stitching portion is mended and carried out thermosetting after yarn, reinforcement again and be fixed to whole vehicle frame.Why adopt such connecting method, because the abnormity place of bicycle frame pipe is limited to the characteristic of polymer composite, without supporting role, make soft multiple material cannot roll in advance special-shaped shape, make comparatively difficulty of moulding, so must adopt the mode of straight pipe splicing to realize; Even if leg-of-mutton support body, can utilize airbag to support in special-shaped t-bend position, but when special-shaped position is greater than threeway, still needs splicing.
When each straight pipe splices at abnormity place, must cut out engages indentation and just can overlap, because preformed pipe fitting is subject to material behavior, its intensity hardness is all higher, thus when cutting out engages indentation, comparatively require great effort, processing procedure operation is loaded down with trivial details; In addition, yarn is mended in stitching portion must reach the bonding strength that certain thickness just can meet this abnormity place, can cause like this weight of whole vehicle frame to increase, and overall appearance sense is not strong.
Summary of the invention
The object of this invention is to provide a kind of carbon fibre composite mixed-forming method, its can make have the multiple material products molding manufacture procedure of form parts simple, guarantee multiple material products intensity and overall appearance, reduce cost of manufacture simultaneously.
For achieving the above object, solution of the present invention is:
A carbon fibre composite mixed-forming method, its step comprises:
Step 1, carbon fiber is steeped to resin-shaped become yarn sheet, make multiple material products preform; Make silica gel mandrel simultaneously;
Step 2, the angular position that airbag is imbedded to preform straight tube position and can be formed loop;
Step 3, at the special pipe place of preform device silica gel mandrel;
Step 4, preform is placed in to mould, when mould pressurizing is heated, airbag is heated to pressurization;
Step 5, die sinking, after multiple material products after to be formed is cooling, take out airbag and silica gel mandrel, just completes the moulding of the multiple material products of concrete special-shaped part.
The order of described step 2, step 3 can be inverted.
The forming temperature of described step 4 is 120-150 ℃, and molding time is at 45-60min.
Adopt after such scheme, the present invention is by the silica gel mandrel yielding feature of expanding with heat and contract with cold, be placed into multiple material abnormity position and carried out the moulding of multiple material products, can realize and there is the one-body molded of the multiple material products of special-shaped part, the molding manufacture procedure of the multiple material products of order is more simple, and can guarantee the intensity of pipe fitting and the globality of outward appearance; Silica gel mandrel can Reusability, the further cost of manufacture of the multiple material products of reduction in addition.
Accompanying drawing explanation
Fig. 1 is that the invention process is in the structural representation of vehicle frame moulding.
The specific embodiment
Below in conjunction with accompanying drawing, explain embodiments of the present invention:
The present invention has disclosed a kind of carbon fibre composite mixed-forming method, and as shown in Figure 1, the present invention be take bicycle rack and described as example, the forming process that it is concrete:
Step 1, carbon fiber is steeped to resin-shaped become yarn sheet, make composite material frame goods preform 1, the making in this stage is at straight tube place, directly to roll up yarn, bag yarn forming, and paste yarn reinforcement at abnormity place, connects; Make silica gel mandrel 3 simultaneously;
Step 2, the angular position that airbag 2 is imbedded to preform 1 straight tube position and can be formed loop;
Step 3, at the special pipe place of preform 1 device silica gel mandrel 3;
Step 4, complete after the support of preform inner chamber, preform 1 is placed in to mould 4, when mould pressurizing is heated, airbag is heated to pressurization, forming temperature is now 120-150 ℃, molding time is at 45-60min, in this section of process, at the abnormity place of preform 1, the material characteristics that expanded with heat and contract with cold by silica gel material, under the condition of mould high temperature, expand, with airbag, equally the inwall of special piece is had to a contention effect, the combination that makes polymer composite is consolidation more;
Step 5, die sinking, after multiple material products after to be formed is cooling, take out airbag, after silica gel mandrel shrinkage simultaneously, can from special pipe, take out smoothly, just complete the moulding of the multiple material bicycle rack of concrete abnormity part.
Certainly, the order of above-mentioned step 2, step 3 can be inverted, and first puts silica gel mandrel 3 and still first exits and all can according to 2.
The present invention utilizes the silica gel mandrel 3 yielding feature of expanding with heat and contract with cold, be placed into multiple material abnormity position and carried out the moulding of multiple material products, to realize, there is the one-body molded of the multiple material products of special-shaped part, the molding manufacture procedure of the multiple material products of order is more simple, and can guarantee the intensity of pipe fitting and the globality of outward appearance; Silica gel mandrel 3 can Reusability, the further cost of manufacture of the multiple material products of reduction in addition.
