根据碱催化阴离子聚合原理 ,制备了连续长碳纤维增强单体浇铸尼龙复合材料 (简称CL/PA)。在MM -2 0 0型磨损试验机上考察了碳纤维含量和试验条件对其摩擦性能的影响 ,并利用扫描电子显微镜对其摩擦性能和磨损机制进行了考察。分析结果表明 :碳纤维的体积分数在 35 %左右时增强效果最好 ,CL/PA复合材料的摩擦系数和磨损率随着载荷的增加而减小。其磨损机制主要表现为粘着磨损和碳纤维的破碎和磨平的特征
Based on the principle of base catalyzed anionic polymerization, a continuous long carbon fiber reinforced monomer cast nylon composite (CL / PA) was prepared. The effects of carbon fiber content and test conditions on the tribological properties were investigated on a MM-200 wear tester. The tribological properties and wear mechanisms of the samples were investigated by scanning electron microscopy. The results show that the best effect is obtained when the volume fraction of carbon fiber is about 35%, and the friction coefficient and the wear rate of CL / PA composite decrease with the increase of load. The wear mechanism is mainly manifested as adhesive wear and carbon fiber broken and polished features
