Abstract：Copper-based powder metallurgy friction materials have been gradually applied to fast train brake friction materials for its homogeneous, good thermal conductivity, high abrasion resistance, friction factor stability, etc. At present, the domestic copper-based P/M brake pads have basically met the demand of 250 Km/h trains, but the brake pads of high-speed trains above 300 Km/h still rely on imports. In this paper, the effects of metal powders, metal compounds and ceramic particles on the friction and wear properties of copper-based powder metallurgy are reviewed. The main problems in the preparation of copper-based powder metallurgy friction materials for high-speed trains are pointed out, and the development prospect of copper-based powder metallurgy friction materials is prospected.
