Vacuum infusion process was employed for the fabrication of carbon fiber reinforced polymeric (CFRP) composites modified by graphene. Three different methods were utilized for the incorporation of graphene into the CFRP composites. In the first and second approaches, graphene sheets were respectively electrosprayed on the surface of carbon fibers as interface modifiers and dispersed into the epoxy resin to improve the matrix properties. The third method includes the concurrent usage of both treatments just mentioned above. The viscoelastic behavior of composites was examined by dynamical mechanical testing at different temperatures, frequencies and graphene integration configurations. In addition, the effect of graphene on the electrical conductivity, thermal diffusivity and electro-thermal performance of composites was also studied in detail. The results indicated that the fiber reinforced polymeric composites gain multi-functionality while preserving their mechanical integrity for all graphene integration configurations with significant improvements when graphene is used simultaneously as the interface modifier and the matrix reinforcement.

真空灌注工艺用于制造石墨烯改性的碳纤维增强聚合物（CFRP）复合材料。利用三种不同的方法将石墨烯掺入CFRP复合材料中。在第一种方法和第二种方法中，分别将石墨烯片电喷涂在碳纤维表面作为界面改性剂，然后分散在环氧树脂中以改善基体性能。第三种方法包括同时使用上述两种处理方法。通过在不同温度，频率和石墨烯集成构型下的动态力学测试，研究了复合材料的粘弹性行为。此外，还详细研究了石墨烯对复合材料的电导率，热扩散率和电热性能的影响。
