▎ 摘　　要

NOVELTY - Carbon/carbon composite material comprises 90-100 pts. wt. three-dimensionally woven graphite carbon fiber mesh, 20-60 pts. wt. graphite, and 5-10 pts. wt. graphene. The graphite is made from pitch containing condensed aromatic hydrocarbons, and the graphene is made from chemically modified graphene components. USE - Carbon/carbon composite material. ADVANTAGE - The graphite is made from pitch containing condensed aromatic hydrocarbons, and the graphene is made from chemically modified graphene components. The average thermal conductivity of the graphene-enhanced carbon/carbon composite is 675.71 Watts per meter-Kelvin because of the high degree of graphitization of raw materials and the good three-dimensional distribution of graphene. The composite material has higher heat conduction/heat dissipation efficiency and wider application range.
