NOVELTY - Wave absorbing prepreg comprises resin, graphene and fiber cloth, where the volume fraction of graphene is 3-40% of the resin. USE - The prepreg is useful in wave absorbing composite material (claimed). ADVANTAGE - The prepreg has light weight, thin thickness, excellent flexibility, compression and excellent absorbing performance, can realizes different frequency bands of high absorption. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing wave absorbing prepreg comprising hot-melting resin, adding graphene in hot melted resin to obtain mixture, adding the mixture into film, heat pressing the fiber cloth and glue to obtain final product; and (2) wave absorbing composite material, molding from wave absorbing prepreg.
