摘　　要：采用冷压烧结工艺制备了短碳纤维增强铜基复合材料,考察了该复合材料的干摩擦磨损性能。讨论了短碳纤维含量、载荷、转速等对复合材料摩擦性能的影响。结果表明:复合材料的耐磨性能明显优于基体材料;随着碳纤维含量的增加复合材料的耐磨性能进一步提高;随载荷和转速的提高,摩擦系数和磨损量也随之增加;复合材料由纯铜的粘着磨损转变为剥层磨损,并均伴有一定的氧化磨损。The copper matrix composites reinforced with short carbon fibers （CFs） were prepared by cold press and sintering using copperized short CFs. The friction and wear properties of the composites were tested. The influence of short CFs contents, load and rotating speed on tribological behavior of composites was discussed. The results showed that the wear resistance improved with the increasing of fiber volume fraction. Both friction coefficient and wear mass loss increased with increasing load and rotating speed respectively. The wear mechanism was transferred from abrasive wear for pure Cu to delamination wear for Cu/short CFs composites.
