Preparation method of graphite film heat conduction reinforcement composite material
The invention relates to a preparation method of a graphite film heat conduction enhancement composite material. According to the method, a graphite film/graphene film and PAN-based carbon fibers are compounded to prepare a graphite film heat conduction enhancement unit. A graphene heat conduction enhancement unit is used for preparing the composite material, the chemical inertness of the surface of the graphite film can be overcome, the strength of a matrix is enhanced, and meanwhile, a heat transfer channel of the graphite film/graphene film can be completely kept. Compared with a PAN-based carbon fiber reinforced composite material, a very high heat-conducting property is achieved, and compared with mesophase pitch fibers, the preparation cost is low, and the preparation process is simple.
本发明涉及一种石墨膜导热增强复合材料的制备方法。该方法将石墨膜/石墨烯膜与PAN基碳纤维复合制备出石墨膜导热增强单元。利用石墨烯导热增强单元制备复合材料，可以克服石墨膜表面的化学惰性，增强基体的强度，同时可完整的保持石墨膜/石墨烯薄膜的传热通道。本发明相比PAN基碳纤维增强的复合材料，具有非常高的导热性能，相比中间相沥青纤维，制备成本低，制备工艺简单。
