▎ 摘 要
NOVELTY - Composite material comprises one three-dimensional graphene layer and one fiber composite material layer, where three-dimensional graphene layer is formed by stacking three-dimensional graphene films, and at least one side of the three-dimensional graphene film has a fiber composite material layer. USE - Composite material used in thermal conductivity and/or bulletproof (claimed). ADVANTAGE - The composite material form an effective heat conduction channel inside the composite material, realizes the rapid conduction of heat on the composite material, has the characteristics of light weight, high strength, good flexibility, good air permeability, and is especially suitable for the design of heat conduction or body armor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite material, which involves: (A) preparing three-dimensional graphene film; and (B) laying up one layer of three-dimensional graphene film and one layer of fiber composite material, and one side of the three-dimensional graphene film has a fiber composite material layer.
