| 摘 要： | 采用玻璃微珠(GB)增强聚酰胺6(PA6),固体润滑剂聚四氟乙烯(PTFE)、石墨(Gr)降低PA6的摩擦系数。重点研究GB含量、PTFE、Gr含量及配比对PA6复合材料的拉伸强度、冲击强度和摩擦系数的影响。结果表明,GB可提高PA6的力学性能,随着GB含量增大,PA6复合材料的拉伸强度和冲击强度先增大后减小,GB含量为15%时,其综合力学性能较好,但GB不能降低PA6的摩擦系数。固体润滑剂不能进一步提高PA6/GB(85/15,质量比)的力学性能,但是能大大降低其摩擦系数,且PTFE和Gr对降低摩擦系数有协同效应,PTFE/Gr为10/5时,PA6复合材料的摩擦系数仅为0.131 9。
