【摘要】 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更多还原

【Abstract】 Continuous carbon fiber-reinforced monomer casting nylon (C L/PA) composites have been prepared by anionic polymerization of caprolactam.It was observed with the MM-200 wear trial machine that carbon fiber content and trial conditions affected the tribological properties and wear mechanism with scan electron microscope.The results indicate that the effect of C L/PA is better when carbon fiber volume fraction is about 35%.Its wear mechanism exhibited mainly adhesive wear and carbon fiber fragmentation and rubdown.更多还原
