利用M-2000型摩擦磨损试验机考察载荷以及纳米Si_3N_4/SiO_2与玻璃纤维的混合填料对PA6复合材料摩擦磨损性能的影响,用扫描电子显微镜观察分析磨损表面形貌及磨损机理。结果表明:纳米材料与玻璃纤维的协同作用显著改善了材料的摩擦磨损性能,以3%纳米Si_3N_4与玻璃纤维混杂填充耐磨性最佳;以5%纳米SiO_2与玻璃纤维混杂摩擦因数最低。
The friction and wear properties of PA6 composite were investigated by using M-2000 friction and wear tester and the effects of the mixed filler of nano-Si_3N_4 / SiO_2 and glass fiber on the wear and abrasion properties of PA6 composite. The wear surface morphology and wear mechanism were analyzed by scanning electron microscope. The results show that the synergistic effect of nanomaterials and glass fibers can significantly improve the friction and wear properties of the materials. The best wear resistance is obtained when 3% nano-Si_3N_4 is mixed with glass fiber, and the lowest is 5% nano-SiO_2 with glass fiber.
