Description
Technical field
The present invention relates to a kind of fibre, particularly relate to a kind of forming method and finished product thereof of fibre.
Background technology
Carbon fiber is a kind of fiber that is made up of carbon atom, and " lines " are extremely very thin, though diameter approximately has only 0.005 millimeter～0.01 millimeter; Intensity but can reach 7～9 times of steel, and therefore weight is less than 1/4 of steel; Taken into account lightweight and high-intensity demand, added its special braiding lines, made carbon fiber product; Become the synonym of high texture, and be widely used in various product.
Because carbon cloth is softness and tool is not qualitative quite, therefore, carbon fiber product in the past all is with manual type, with carbon cloth binding to desired thickness in layer, cuts, is hot pressed into predetermined shape again.Not only labor intensive, time, and appearance is subject to the bonding mode, the variation of deflection can only be arranged, and can not be directed against demand, has the appearance of three-dimensional (3D) to change, and adds the cost height, causes price also high.
Announcing No. 590888 " manufacturing approach of plastic composites and composite product " patent of invention case, No. 572825 " method of forming composite goods and this composite " patent of invention case of bulletin, No. 512830 " it is the object of structural wood that the fibrous composite of tool high interfacial strength reaches with this composite " patent of invention case of bulletin with TaiWan, China is example; Though can form a composite wood with the heating and pressurizing mode with other material layer and fibrous material layer; Reach the purpose that reduces cost; But still can be because of being to cohere layer by layer with manual work; Cut again, hot-forming, make appearance be subject to the bonding mode equally, the variation of deflection can only be arranged; And can not be directed against demand, there is the appearance of three-dimensional (3D) to change.
Consult Fig. 1, Fig. 2; Be example with No. 317926 " the fastening combined structure of working of plastics and carbon fiber spare " novel patent case of TaiWan, China patent in addition; Mainly be to be furnished with one deck bond 12, then, in advance this carbon fiber spare 11 be contained in the die cavity 21 of a mould 2 carbon fiber spare 11 1 surfaces coated; This working of plastics 13 of ejection formation makes this working of plastics 13 be combined as a whole with this carbon fiber spare 11 through this bond 12 again.
Yet, because this carbon fiber spare 11 is a kind of weaving cotton cloth, soft and the mobile or distortion because of external force easily of matter; Therefore; Though aforementioned die cavity 21 can be any moulding, the pressure in the time of can penetrating because of this working of plastics 13 has and pushes the situation that the fine part 11 of this carbon produces fold; So, still be not suitable for appearance variations such as moulding concave, convex fluctuating.
