-
摘要: 本文制备了结构-性能不同的纤维增强聚乙烯基复合材料,研究了纤维含量及纤维取向对聚乙烯基复合材料力学性能和摩擦性能的影响.实验结果表明:纤维含量及取向对玻纤增强的聚乙烯基复合材料的摩擦磨损性能影响较大.沿垂直纤维方向摩擦时磨损量最少,沿平行玻纤方向摩擦时摩擦系数μ最低.玻纤含量为30%的聚乙烯基复合材料耐磨性好,摩擦系数低,综合力学性能优良,是一种有应用前景的高分子抗磨材料.Abstract: Tribological behavior of glass fiber reinforced HDPE(GF/HDPE) composites was studied,focusing on the effects of the content and orientation of glassfibre on the mechanical and tribological properties of the polyethylene based composites.Experimental resups showed that fiber content and orientation have great influences on the tribological behavior of the composite.The wear loss is the least in the direction vertical to fibers orientation,and the fiction coefficient is lower in the direction parallel with fibers orientation.HDPE composite reinforced by 30% glassfiber has good comprehensive mechanical and tribological properties,which can be a good candidatefor the tribological applications under severe conditions.
