摘　　要：该研究采用了传统的混合方法和溶剂辅助混合方法制备了填充纳米氧化铝的制动摩擦材料,研究结果表明,纳米氧化铝在基体当中,产生了稳定的摩擦层和容易传导路径的作用,可以有效地降低摩擦系数,改善了力学、磨损和导热性能,更加适用于高速、高温、重压以及高机械强度等使用要求,是生产汽车摩擦片和离合器片较理想的材料。In this study,the traditional mixing method and solvent-assisted mixing method were used to prepare nano-alumina-filled brake friction materials.The results show that nano-alumina in the matrix produces a stable friction layer and an easy conduction path.It effectively reduces the friction coefficient,improves the mechanical,wear and thermal conductivity,and is more suitable for high-speed,high-temperature,heavy-pressure and high-mechanical strength requirements.lt is an ideal material for the production of automobile friction plates and clutch plates.
