[background technology]
Carbon fiber, owing to having the advantages such as lightweight, intensity is high, rigidity is good, is therefore widely used in many industrial products such as aerospace industry, auto industry, 3C electronic industry and consumer products field.
General carbon fiber is containing epoxy resin dipping with carbon fiber layer, make its surface there is microviscosity, then with one deck or some layer models, molded required shape of product by mould in the mode of high pressure and high temperature, thereby obtained the splendid carbon fiber product of a rigidity.But carbon fiber is easily subject to the impact of stack direction, hot pressing condition and condition of cure etc. and produces distortion in hot-forming process.Refer to shown in Fig. 1, Fig. 1 is the carbon fiber product 10 of hot-forming rear generation, there is micro-indent by appearance 11 to non-appearance 12 directions in these carbon fiber product 10 its middles, and the phenomenon of adjusting hot compression parameters and cannot improve this distortion under the restriction of stack direction, has affected follow-up use.
In view of this, be in fact necessary to develop a kind of carbon fiber processing method, with improve above-mentioned when hot-forming carbon fiber product there is the problem of distortion.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of carbon fiber processing method, this carbon fiber processing method can improve above-mentioned when hot-forming carbon fiber product there is the problem of distortion.
In order to achieve the above object, carbon fiber processing method of the present invention, it comprises the following steps:
(1) carbon fibre initial rinse fabric is stacked into carbon fiber stratiform structure, this carbon fiber stratiform structure comprises appearance and non-appearance;
(2) cut one with described carbon fiber stratiform structure size and the suitable resin molding of thickness;
(3) resin molding is overlayed to the non-appearance of described carbon fiber stratiform structure;
(4) by the carbon fiber stratiform structure after stacking and resin molding pressing;
(5) the carbon fiber stratiform structure after pressing and resin molding are placed in to hot pressing die hot-forming;
(6) carbon fiber product of gained is taken out in hot-forming rear die sinking.
Alternatively, in described step (1): carbon fibre initial rinse fabric adopts 0 degree or 90 degree interactive stackings.
Alternatively, in described step (2): the material of resin molding is PC, PET, PP, PA, PS or ABS.
Alternatively, in described step (5): the hot pressing die of employing is die, the appearance of described carbon fiber stratiform structure and the laminating of the die face of this hot pressing die.
In addition, the present invention also provides a kind of carbon fiber product, and this carbon fiber product is the product producing after described carbon fiber disposal methods.
Alternatively, described carbon fiber product is tabular product.
Compared to prior art, carbon fiber processing method of the present invention and products thereof, by stacking one deck resin molding in the non-appearance of carbon fiber stratiform structure, because the shrinkage factor of resin molding in the time solidifying is greater than the shrinkage factor of described carbon fibre initial rinse fabric, therefore when hot-forming, resin molding can resist described carbon fiber stratiform structure and occurs indent, has improved the problem that distortion appears in carbon fiber product when hot-forming.

[detailed description of the invention]
For object of the present invention, method step and effect are had to further understanding, be now described with reference to the accompanying drawings as follows.
Refer to shown in Fig. 2, Fig. 3 and Fig. 4, it has illustrated respectively the schematic diagram of the flow chart of steps of carbon fiber processing method one preferred embodiment of the present invention, carbon fiber processing method of the present invention step (3) in a preferred embodiment and the schematic diagram of carbon fiber processing method of the present invention step (5) in a preferred embodiment, in this preferred embodiment, carbon fiber processing method of the present invention, it comprises the following steps:
Step S110: carbon fibre initial rinse fabric is stacked into carbon fiber stratiform structure 100 by the mode of 0 degree or 90 degree interactive stackings, and this carbon fiber stratiform structure 100 comprises appearance 101 and non-appearance 102;
Step S120: cut one with described carbon fiber stratiform structure 100 sizes and the suitable resin molding 200 of thickness, the material of this resin molding 200 can be PC, PET, PP, PA, PS or ABS, wherein the size of this resin molding 200 is equal to or greater than the non-appearance 120 of this carbon fiber stratiform structure 100, and the thickness of this resin molding 200 is less than the thickness of described carbon fiber stratiform structure 100;
Step S130: refer to shown in Fig. 3, resin molding 200 is overlayed to non-appearance 102 places of described carbon fiber stratiform structure 100;
Step S140: by the carbon fiber stratiform structure 100 after stacking and resin molding 200 via hot pressing device contraposition pressing, in pressing process, not only can remove bubble, and hot pressing device can heat described carbon fiber stratiform structure 100 and resin molding 200 in the process of pressing, make this carbon fiber stratiform structure 100 and resin molding 200 bonding and shape;
