采用层压法制备了四种聚酯纤维布增强环氧树脂基复合材料,研究了不同填充物(纳米Al2O3颗粒和PTFE)对不同织物取向复合材料拉伸性能和摩擦磨损性能的影响,分析了拉伸断口和摩损表面的形貌.结果表明:加入PTFE使复合材料的经向和纬向的拉伸强度和弹性模量分别提高了1.4%,11.2%和31.5%,22.1%,纳米Al2O3颗粒的加入使复合材料的经向和纬向的拉伸强度和弹性模量分别提高了4.2%,14.2%和34.9%,26.3%:PTFE和纳米Al2O3均能提高复合材料的耐磨损性能,PTFE的加入使复合材料的摩擦因数降低了22.5%、磨损率减少了78.1%,Al2O3的加入使复合材料的摩擦因数增加了21.3%、磨损率减少了94.1%.
