Composite fiber material structure

The present invention relates to a composite fiber material structure, and more particularly to a composite fiber material structure comprising titanium wire or carbon fiber.

Generally, the carbon fiber material is obtained by impregnating a carbon fiber woven layer and absorbing an epoxy resin to make the surface of the carbon fiber woven layer have a viscous surface layer, and then forming a desired product through a hot pressing process through a mold or a plurality of layers. Shape, and get a product of carbon fiber material with excellent steel properties. The carbon fiber material has the advantages of light weight, high strength and good steel properties.
