▎ 摘　　要

NOVELTY - Carbon fiber composite comprises a polymer matrix, carbon fiber provided within the polymer matrix, where the carbon fiber is surface coated with carbon nanotube/graphene oxide composite. USE - The carbon fiber composite is useful in aircraft material and electromagnetic wave shielding material (claimed). ADVANTAGE - The carbon fiber composite can be prepared from carbon nanotubes with high electrical conductivity and graphene oxide without changing their structure and physical properties, and includes carbon fiber coated with graphene oxide to prevent formation of cracks. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing carbon fiber composite, comprising (i) coating carbon nanotube/graphene oxide composite on carbon fiber, and (ii) laminating multiple carbon fibers coated with carbon nanotube/graphene oxide composite, and adding the obtained laminate into the polymer matrix.
