摘　　要：介绍了半金属摩擦材料的组成,用二水平七因素的正交设计对半金属摩擦材料的配方进行优化设计。通过对试验结果和极差值的分析,得出了各组分对摩擦系数和磨损率影响的重要次序,为优化配方、提高材料质量、调整摩擦系数提供了依据。经综合评分,推荐出较好的配方组合:13.9%腰果壳油改性树脂,32.4%钢纤维,7.4%海泡石纤维,11 1%石墨,2.8%二硫化钼,13 9%碳化硅,5.6%高岭土,7.4%硫酸钡,2.8%氧化镁,1.8%氧化铁,0.9%轮胎粉。The paper simply introduces the components of semi-metallic friction materials. The orthogonal design experiment was used to optimize the formulation. According to the layout of 2 levels with 7 factors (2~7), 8 different formulations were examined for friction coefficient and wear. An analysis of the margin of experimental data, showed that the relative importance of the different components affectsed the tribological properties. In particular, the friction coefficient and wear at high temperature were strongly affected by the resin. The orthogonal experiment provides a good method for improving the quality of brake linings and adjusting the friction coefficient. After fuzzy grading in friction coefficient and wear of each formulation, the best one was selected, it comprised (wt,%) 13.9% modified resin, 32.4% steel fibre, 7.4% fibriform sepiolite, 11.1% graphite, 2.8% MoS_2, 13.9% SiC, 7.4% Ba_2SO_4, 5.6% kaoline, 2.8% MgO, 1.8% FeO and 0.9% rubber powder.
