▎ 摘  要

NOVELTY - Composite material comprises carbon reinforcement fibers and a matrix material comprising 0.1-100 wt.% functionalized graphene nanoplatelets having imide groups formed on a surface of the graphene nanoplatelets. USE - The composite material is useful in an aircraft (claimed). ADVANTAGE - The composite material serves as a supplement to or as a replacement for either the carbon reinforcement material or the resin matrix material to increase strength of the composite material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an aircraft comprising composite structures made from the composite material; (2) increasing (M1) strength of the composite material comprising carbon reinforcement fibers and the resin matrix material, comprising mixing functionalized graphene nanoplatelets into the resin matrix material to form a graphene-resin mixture, where the functionalized graphene nanoplatelets has imide groups formed on a surface of the graphene nanoplatelets and epoxide groups formed on at least one edge of the graphene nanoplatelets, combining the graphene-resin mixture with many carbon reinforcement fibers to form a prepreg material, and curing the prepreg material to form the composite material; (3) increasing (M2) strength of the composite material, comprising combining the resin mixture with the carbon reinforcement fibers to form prepreg material, depositing functionalized graphene nanoplatelets onto a top surface of the prepreg material to form a graphene interlayer, the functionalized graphene nanoplatelets having imide groups formed on surface of the graphene nanoplatelets and epoxide groups formed on at least one edge of the graphene nanoplatelets, laying a second prepreg material on top of the graphene interlayer, and curing the prepreg material, the graphene interlayer and the second prepreg material to form the composite material; and (4) increasing (M3) strength of the composite material, comprising forming a bed of the carbon reinforcement fibers, depositing functionalized graphene nanoplatelets through top surface of the bed of the carbon reinforcement fibers to penetrate the entire bed of fibers and form a carbon fiber/graphene prepreg material, the functionalized graphene nanoplatelets having imide groups formed on surface of the graphene nanoplatelets and epoxide groups formed on at least one edge of the graphene nanoplatelets, and curing the carbon fiber/graphene prepreg material to form the composite material.
