Research Progress and Prospect of Copper-Carbon Composites for Current-Carrying Friction
Copper-carbon(carbon material mainly includes graphite,carbon fiber,carbon nanotubes,graphene,etc.)composite materials are widely used as current-carrying friction pairs in the field of aerospace,rail transit,power electron-ics,weapons and other fields due to their excellent electrical conductivity,thermal conductivity,lubrication and other prop-erties.With the increasingly stringent service conditions of current carrying friction pairs,the performance requirements for copper-carbon composite materials are becoming higher.The types and compositions of copper-carbon composite materials were introduced,the problems existing in copper-carbon composite materials were pointed out,such as low strength,non wetting between copper matrix and carbon material reinforcement phase.The interface improvement and preparation meth-ods of copper-carbon composite materials were reviewed,and the development direction of copper-carbon composites in the future was prospected.
