Composite layered product of small thickness for use in production of sport footwear, comprises core sandwiched between two skins of high mechanical resistance, made of carbon fibers immersed in epoxy resin

摘要

Composite product has structure comprising composite core (2) sandwiched between two composite skins (3, 4), with at least one part of fibers of core (2) having significantly lower mechanical resistance than at least one part of fibers of one and/or other skin (3, 4). Independent claims are also included for (1) production of layered composite as claimed, by superposing one or more pleated constituents of core and one or more pleated constituents of skin, with the pleats formed of woven or non-woven and oriented or not micro-fibers cloth, which can be pre-impregnated or not with resin; (2) use of layered composite as claimed in making sport footwear, and sport articles such as skis, surfing boards, skate-boards, golf clubs, tents etc.; (3) articles obtained using layered composite material as claimed; (4) use of material as claimed to produce layered composite skin .
