NOVELTY - Modified carbon fiber/epoxy composite material, is claimed. The preparation of carbon fiber/epoxy composite material comprises (i) mixing an epoxy resin with graphene liquid to obtain a first mixture; (ii) adding liquid epoxy cross-linking curing agent into the first mixture, to obtain a second mixture; (iii) adopting composite material molding process, using carbon fiber and the second mixture as raw material, so that the cross-linked and cured liquid epoxy resin is integrated with the carbon fibers. USE - Used as a modified carbon fiber/epoxy composite material. ADVANTAGE - The composite material has good consistency. The method is simple, has high production efficiency, and is suitable for large scale production.
