▎ 摘　　要

NOVELTY - A preparation method of electrothermal carbon fiber composite material based on graphene oxide crosslinking reinforcement comprises selecting one of carbon fiber, carbon fiber yarn or carbon fiber fabric as the base material, coating the graphene oxide aqueous solution on the surface of the base material, and solidifying and forming the carbon fiber composite material through the vacuum-assisted resin transfer molding (VARTM) process. USE - The method is used for preparing electrothermal carbon fiber composite material based on graphene oxide crosslinking reinforcement, which is used in mechanical equipment, aircraft wings, and electric heating floors (claimed). ADVANTAGE - The electrothermal carbon fiber composite material prepared has excellent electrothermal performance, realizes efficient defrosting, deicing, heating and heat preservation, and has strong practicability.
