摘　　要：研制了一种应用于矿山自卸车刹车片的摩擦材料。该材料将碳纤维、玻璃纤维及矿物纤维混杂作为增强纤维,配合黏结剂与填料组成基本配方,在此基础上添加不同含量的金属粉制备刹车片试样。经定速摩擦试验分析表明,3种纤维混合并添加金属粉后的配方改善了刹车片的热稳定性及耐磨性,将摩擦试验数据进行处理后,优选了刹车片性能最优的摩擦材料配方。The study develops a friction material applied to the brake pads of mining dump trucks.This friction material combines carbon,glass fiber,and mineral fiber as reinforcing fibers,and combined with binders and fillers to form the basic formula.On the basis of this formula,different content of metal powder is added to prepare brake pad samples.After analyzing the constant speed friction test,it is found that the friction material formula mixed with three types of fibers and adding metal powder improves the thermal stability and wear resistance of the brake pads.After processing the friction test data,the optimal friction material formula for brake pad performance is selected.
