Abstract: The rapid development of high technology puts forward higher requirements for the development of high-performance copper materials. Copper matrix composites have been widely used because of their high strength and good electrical and thermal conductivity, wear resistance, corrosion resistance and high-temperature stability; their preparation processes are constantly developing, and great progress has been made in recent years. The characteristics and research progress of the main preparation processes of copper matrix composites, including powder metallurgy technique, casting process, mechanical alloying, internal oxidation, in-situ synthesis, melt infiltration, and friction stir processing, are reviewed. The development direction of copper matrix composite preparation technology in the future is prospected.
