NOVELTY - Method for preparing a three-dimensional carbon fiber reinforced thermoplastic composite material involves mixing chopped carbon fiber and thermoplastic resin-based fiber evenly, and obtaining self-made carbon fiber felt through needle punching molding, and mixing the obtained carbon fiber felt with non-woven fabric to obtain a three-dimensional structure carbon fiber reinforced thermoplastic composite material, where the chopped carbon fiber and the thermoplastic resin-based fiber are uniformly mixed through a suspension, and the suspension comprises a modifying agent, nanoparticles and a nonionic surfactant. USE - The method is used for preparing a three-dimensional carbon fiber reinforced thermoplastic composite material (claimed) used in automobile industry and building industry. Can also be used in building decoration material. ADVANTAGE - The three-dimensional structure carbon fiber reinforced thermoplastic composite material has good interlayer strength, impact resistance, not easy to occur layered damage, antistatic property, good interface compatibility, and good application prospect. The composite plate has good environment-friendly performance, light weight, high rigidity strength, sound-absorbing and noise-reducing, wide application and so characteristics, and can be widely applied to the field of automobile industry and building industry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a three-dimensional carbon fiber reinforced thermoplastic composite material obtained by the above-mentioned method.
