Abstract: High-strength and high-conductivity materials have been the focus of research in the field of materials science because they can bring higher performance and lower energy consumption in a wide range of applications. Due to its excellent mechanical properties and good electrical conductivity, graphene is often introduced into the copper matrix as the most ideal second-phase reinforcement to improve the comprehensive performance. This paper reviewed the research background of graphene reinforced metal matrix composites. The preparation method of graphene reinforced copper matrix composites was described and analyzed in detail. The research status of the mechanical and electrical properties of graphene-reinforced copper matrix composites in recent years was summarized. Finally, the future development of graphene reinforced copper matrix composites was summarized and discussed.
