摘　　要：通过热压成型的方法制备含Sb2S3的聚合物基复合材料,研究Sb2S3含量对复合材料物理力学性能、热稳定性及摩擦磨损性能的影响,借助扫描电镜观察复合材料断面结构及磨损表面形貌。研究结果表明:随Sb2S3含量增加,复合材料的硬度逐渐降低,密度和冲击强度呈先增后减的变化趋势;Sb2S3能提高并稳定复合材料的摩擦因数,增加耐磨性。Sb2S3质量分数为2.3%时,复合材料各项性能最佳,其磨损表面以热磨损和磨粒磨损为主。Polymer matrix composites with different content of Sb2S3 were prepared by heat-press molding method. The effects of Sb： S3 on the physical and mechanical properties, thermal stability and friction and wear properties were investiga- ted, and the section structure and worn surface were observed by using Scanning electron microscopy （ SEM ）. The results show that,with the increasing of Sb2 $3 content, the hardness of composites is decreased gradually, and the density and im- pact strength are increased at first and then reduced. The value and stability of friction coefficient is improved by adding of Sb2S3, and the wear-resistance is also improved. The composite with 2.3 % Sb2S3 exhibits the best properties, whose main wear form is heat wear and abrasive wear.
