▎ 摘　　要

NOVELTY - A nano-toughening carbon fiber composite material is formed by molding and curing 16-20 layers of prepreg, an active layer of graphene/halloysite nanotube composite film and an active layer of carbon nanotube/halloysite nanotube composite film. The active layer of graphene/halloysite nanotube film comprises amino graphene, benzyl glycidyl ether and modified graft long-chain polymer halloysite nanotubes. The active layer of carbon nanotube/halloysite nanotube composite film comprises carbon nanotubes, benzyl glycidyl ether and modified graft long-chain polymer halloysite nanotubes. USE - Nano-toughening carbon fiber composite material (claimed). ADVANTAGE - The multi-dimensional nano-toughening carbon fiber composite material has excellent mechanical property. DETAILED DESCRIPTION - A nano-toughening carbon fiber composite material is formed by molding and curing 16-20 layers of prepreg, an active layer of graphene/halloysite nanotube composite film and an active layer of carbon nanotube/halloysite nanotube composite film. The active layer of graphene/halloysite nanotube film comprises 10-15% amino graphene, 70-80% benzyl glycidyl ether and 10-15% modified graft long-chain polymer halloysite nanotubes. The active layer of carbon nanotube/halloysite nanotube composite film comprises 10-15% carbon nanotubes, 70-80% benzyl glycidyl ether and 10-15% modified graft long-chain polymer halloysite nanotubes. An INDEPENDENT CLAIM is included for preparation of nano-toughening carbon fiber composite material.
