| 摘 要： | 采用浇铸成型法制备了两类双马来酰亚胺复合材料,分别考察了石墨、纳米Si3N4的添加量对复合材料摩擦学性能和力学性能的影响,用扫描电镜对复合材料的磨损表面形貌进行了分析.结果表明:纳米Si3N4对改善双马来酰亚胺的摩擦磨损性能方面比石墨更有效,尤其是当纳米Si3N4的添加量为1.5%(质量分数)时,复合材料的摩擦磨损性能最佳,摩擦系数降为0.25,磨损率下降72%.

| Abstract: | The bismaleimide composite materials filled with graphite and nanometer Si_3N_4 were made by casting method. The effects of graphite and nanometer Si_3N_4 content on tribological properties were evaluated. The morphology of the composite worn surface was studied by Scanning Electron Microscopy, and the wear mechanism of composite materials were also investigated. The result showed that nanometer Si_3N_4 have better effect on decreasing the friction and wear of bismaleimide polymer composites than graphite. Especially,the friction coefficient of the pair was lowered from 0.36 to 0.25 and the wear rate was lowered by 72% when the composite contain 1.5% (mass fraction) nanometer Si_3N_4. |
