Description

Composite board

Technical Field

The utility model relates to a composite board especially indicates carbon fiber composite board.

Background

It is known that carbon fiber composite plates are often used in sports equipment such as sports shoes, sports protectors, back carriers, backpacks, safety helmets, sports helmets and the like.

As known to be a mechanical material with excellent mechanical property, carbon fiber is known to be known as black gold, and has quite wide application in the fields of modern industry and aerospace and aviation. However, carbon fiber, which is a fiber material, has axial strength, and mechanical strength is directionally influenced. The carbon fiber composite board produced by the existing method has certain limitation although the rigidity is strong enough, namely, when the rigidity is strong, the bending deformability is poor; because the carbon fiber composite board is usually produced according to the arrangement and combination of the carbon fibers and the carbon fiber woven cloth in different directions during production, the overall bending property and rigidity of the produced board are certain, and when the overall rigidity of the product is strong, the bending deformation property is small; however, when the deformability is large and the bendability is good, the rigidity becomes weak, which is difficult to achieve when a certain rigidity is locally required and the bendability is also required in some molded products in use. Of course, other materials may be used to replace the required deformability, but this does not guarantee the strength of the product.

Therefore, for some sports equipment and protective equipment which are required to have both strong rigidity and bending deformation functions, the structure of the current carbon fiber composite board cannot meet the requirements. For this reason, the present applicant has made improvements to the structure of the current carbon fiber composite sheet.
