摘　　要：综述提高高速列车制动盘能量和降低盘重方面的研究成果。研究用C—C纤维复合材料、陶瓷材料、铝基陶瓷强化复合材料,以及材料表面强化技术等改善高速列车制动盘材料性能的问题。分析认为C—C纤维复合材料密度低、耐高温性能好,但表现出环境影响摩擦性能的问题;陶瓷材料具有优良的摩擦性能,但具有韧性低的问题;铝基陶瓷强化复合材料密度低,但面临着使用温度较低的问题;材料表面强化技术可提高钢盘的摩擦性能,但仍需要解决不同材料间的结合性能问题。The present paper reviews the researches on braking disc energy heat and reduction of disc weight for high-speed trains. These researches have involved carbon-carbon composite, ceramic materials, aluminum-based ceramic-reinforced composite material and material surface reinforcing technology to improve the material performance for high-speed train braking discs. Carbon-carbon composite has a low density and a good resistanc to high temperature. But its friction and wear properties are influenced by the environment. Ceramic material has excellent tribological performances. However, it has bad tenacity. The aluminum-based ceramic-reinforced composite material has a low density, but it cannot be used in higher temperature. Sprayed coating can enhance the tribological performances of steel disc, but the bonding performances between different materials remain a problem.
