Abstract
The method for manufacturing racket frame with thermoplastic material includes such technological steps as putting carbon fibre or similar long fibre in molten thermoplastic plastic mixture and fusion medium, weaving planar fibre cloth, folding, rolling, baking, cutting, wrapping it around tube, moulding, heating to smelt plastics while aerating high-pressure gas or filling solvent for providing internal pressure for shaping, cooling and demoulding.
Description
The present invention relates to a kind of method for making of thermoplastic compound material racket frame frame, it mainly is with the thermoplastic plastic mixture of carbon fiber or similarly long fibre adding fusion and fuses in the medium, again it is woven into flat fiber cloth, and fold to be dried after the roll extrusion and cut, again it is coated to the body of suitable shape, insert and be heated in the mould more than the plastics fusing point, and setting-up time is squeezed into gases at high pressure or is injected solvent so that interior pressure to be provided, make fiber cloth in die for molding, cooled off die sinking again, can be with the racquet frame of moulding by taking out in the mould.
Because composite has special advantages such as physical property is good and in light weight, so in many industries, all extensively adopted, especially on products such as racket, fishing rod, all existing manufacturer adopts on the bicycle skeleton even, and obtain splendid product quality, wherein selected material then includes carbon fiber, glass fibre, boron fibre etc., the most general with the use of preimpregnation cloth material again, only on existing this series products method for making, do not reach the ripe stage yet, and still have necessity of in addition research and development.
Just with the example that is fabricated to of general racket, the racket that existing this type of composite is made adopts foaming preparation method or air air blast to carry out mostly, the former mainly is the expanded material or the Foamex of inserting strip among composite, and both one are inserted in the mould, and heating makes the expanded material foaming and intumescing, and utilizes the effect of expanding and the composite that is around in the expanded material outside is strutted and be affixed on die for molding; The latter utilizes air compressor that gases at high pressure are provided again, is equipped with in the mould of composite and make gas blow to inner face, the effect that utilizes gases at high pressure outwards to expand, and composite is strutted in mould, and allow composite be close to the mould inboard and moulding; These two kinds of processing modes all have manufacturer to adopt, and all can be in order to produce suitable product, but in practical operation, find, its product has the instability quality phenomenon, find after investigating its reason, the existing mode of utilizing the preimpregnation cloth material to make can cause the skewness of composite, so after moulding, cause the composite thickness difference of each position of product, and can directly have influence on the quality of product.
The composite that is adopted in the existing again processing mode mostly is the heat curing-type composite greatly, it reclaims comparatively difficulty, and can cause environmental issue, on the other hand because in existing this type of work flow, most step all relies on manpower to carry out, so the quality of its product can be subjected to artificial factor again, process with manpower simultaneously and more can have influence on whole production efficiency.
Main purpose of the present invention is: the method for making that a kind of thermoplastic compound material racket frame frame is provided, it is with the thermoplastic plastic mixture of carbon fiber or similarly long fibre adding fusion and fuses in the medium, again it is woven into flat fiber cloth, and allow its production and processing be undertaken by automation equipment fully, and then fiber cloth folded to be dried after the roll extrusion cut, again it is coated to the body of suitable shape, insert and be heated in the mould more than the plastics fusing point, and setting-up time is squeezed into gases at high pressure or is injected solvent so that interior pressure to be provided, make fiber cloth in die for molding, cooled off die sinking again, can be with the racquet frame of moulding by taking out in the mould, make whole processing more rapid, and product quality more can accurately be controlled.
