Abstract: Interface, as an important component of composite materials, acts as a transfer load, and affects the overall properties of composites. The surface of carbon fiber belongs to graphite disordered structure, and the crystallite is orderly and inert. Therefore, it is difficult for it to combine with the resin matrix. Increasing the specific surface area, the roughness of the fiber or introducing active functional groups to the fiber can improve the surface wettability, mechanical and chemical combination and improve the interface properties of composite materials. The grafting of carbon nanomaterials onto the surface of carbon fibers is one of the effective methods to improve the interfacial properties. In this paper, the preparation methods of grafting carbon nanotubes and graphene oxide onto carbon fibers, interface design and interface enhancement mechanism were reviewed and analyzed. The development trends and prospects of grafting carbon nanomaterials onto carbon fibers and interface performance evaluation methods also were discussed.
