▎ 摘　　要

NOVELTY - Preparing carbon fiber enhanced body comprises (i) providing carbon fiber, surface of the carbon fiber, carrying out oxidation treatment, taking carbon fiber, silicon compound, and coupling agent, mixing and reacting to obtain silanol group with the carbon fiber, (ii) the silanol group with the carbon fiber is added with graphene oxide mixture liquid, surface grafting with silanol group of carbon fiber to obtain the product. USE - The method is useful for preparing carbon fiber enhanced body (claimed).
