摘　　要：分别研究了不同条件下连续C纤维和三维编织纤维增强铸型尼龙复合材料的摩擦磨损性能,并对磨痕和磨屑表面形貌进行了观察和分析。结果表明:干摩擦条件下三维编织C纤维增强铸型尼龙(简称C3D/MCPA)复合材料的磨损率明显低于连续C纤维增强铸型尼龙(简称CL/MCPA)复合材料;水润滑条件下C3D/MCPA复合材料的摩擦系数和磨损率几乎为干摩擦时的50%。三维编织C纤维/芳纶纤维混杂增强铸型尼龙(简称HF/MCPA)复合材料中随C纤维相对体积比的提高,磨损率下降而摩擦系数变化不大。The friction and wear properties of the continuous fiber and 3-dimensional braided fiber reinforced nylon-matrix composites were investigated under different conditions. The worn surfaces and wear debris were observed and analyzed. The results show that the wear resistance of the composites increases with the increase of the carbon fiber volume fraction under dry friction. Wear rate of 3-D braided carbon fiber reinforced MCPA (C3D/MCPA) composites is lower than that of continuous carbon fiber reinforced MCPA (CL/MCPA) composites. Friction coefficient and wear rate of C3D/MCPA composites under water friction are almost 50 percent of those under dry friction. Wear rate of 3-D carbon/Kevlar hybrid fiber reinforced MCPA (HF/MCPA) composites decreases with the increase of the carbon fiber volume fraction, but its friction coefficient has no significant change.
