摘要: 本文研究了玻纤/环氧复合材料的粒子冲击磨损问题.结果表明:随粒子冲击速度的增加,材料的磨损率呈指数增加;随粒子冲击角度的增加,材料的磨损率先增加,在90°附近出现最大值,然后下降,在0°～180°内磨损曲线呈对称分布;磨损率还与材料中纤维取向有关,当纤维与磨面平行时,材料的耐磨性最低,当纤维与磨面垂直时,材料的耐磨性最高.Abstract: A study was made to solid particle erosion in glass/epoxy composites.The results are shown that theerosion rate increases with theincreasing of diameter, volocity and impact angle of the solid particles.The erosion rate is also related with fiber orientation,it is minimum at 0°:and maximum at 90°.
