摘　　要：分析了重载汽车刹车片的失效特点和性能要求,提出了材料改性方案,研制了一种半金属无石棉刹车片摩擦材料。通过对基体材料粘结剂中的树脂进行硼-桐油复合改性,多种碳元素材料按比例复合添加等工艺,改善了摩擦材料的热稳定性和耐磨性。经过摩擦试验分析,所得到的结果验证了这种刹车片性能可满足重载车的使用要求。The failure characteristics and performance requirements of brake pad used in heavy vehicle were studied. The materials modification scheme was proposed, and a kind of half-metallic non-asbestos friction material for brake pad was developed.Through the matrix binder resin modified by boron tung oil and various carbon materials adding according to some proportion and other processes, the thermal stability and wear resistance of friction material improve. After the analysis of friction and wear experiment, the obtained results verify the brake performance, which can meet the requirements of overloaded vehicles.
