▎ 摘　　要

NOVELTY - Forming (M1) a graphene-infused fiber composite comprises: providing graphene consisting of graphene particles having a mean particle diameter less than 10 mu ; providing the graphene particles in a solvent to form a mixture, where the concentration of graphene in the mixture is 0.5-3.5 wt.%; and applying the mixture to a surface of a fiber composite layer. USE - The method is useful for forming a graphene-infused fiber composite which is used as air frame materials for aircraft. ADVANTAGE - The method provides: means of achieving increased graphene loading within the polymer of carbon fiber composite material, where this increased graphene loading improves the electrical and thermal conductivity and phonon transport properties of the carbon fiber composite material, and improves the affinity between the polymer matrix and the carbon fiber mesh, so that certain modes of failure, including delamination at the matrix-fiber interface, may be reduced and/or prevented; means for more selectively controlling and varying the concentration and distribution of graphene throughout a carbon fiber composite material, this improved thermal and electrical properties may allow metal meshes typically included in carbon fiber composite air frames to be obviated, so that the weight of the air frame is reduced, permitting greater payload capacity and thus efficiency of the aircraft; and graphene infused, enriched or enhanced carbon fiber composite that has concentration of graphene throughout the polymer matrix in excess of an electrical conduction threshold (e.g. percolation threshold required for long range conductivity), thermal conductivity threshold, and/or a mechanical performance threshold (e.g. required to prevent certain modes of delamination). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) forming or separating (M2) a fiber composite, comprising causing an electrical current within a layer of graphene particles provided between layers of a fiber composite, where each layer of fiber composite comprises a polymer, and the electrical current causes the polymer to melt; (2) a graphene-infused fiber composite comprising a fiber and polymer layer and graphene particles; and (3) a system configured to carry out the method (M1).
