研究了芳纶浆粕纤维增强环氧复合材料在干摩擦和水润滑条件下的摩擦磨损性能，探讨了纤维含量对复合材料摩擦磨损性能的影响，并分析了复合材料的磨损机理．结果表明：芳纶浆粕纤维能够大幅度提高环氧树脂的摩擦磨损性能；当纤维体积分数为40％时，复合材料的比磨损率最小；在水润滑条件下，复合材料的摩擦系数和磨损率均比干摩擦下的明显降低，这是由于水起到了润滑和冷却作用；干摩擦时的磨损机理为粘着磨损和塑性变形，水润滑时主要为犁削和轻微的磨粒磨损． |

Friction and wear behavior of Kevlar pulp reinforced epoxy composites against stainless steel under dry sliding and water lubrication was evaluated. Effects of Kevlar pulp content on tribological properties of the composites were investigated and wear mechanisms were discussed. Incorporation of Kevlar pulp into epoxy improves the friction and wear property considerably. Optimum wear reduction was obtained when the volume fraction of Kevlar pulp is 40 Vol%. Neat epoxy and its composites sliding against stainless steel register lower friction coefficients and wear rates under water lubrication than under dry sliding, owing to the boundary lubricating and cooling effect of distilled water. Adherence and plastic deformation are dominant under dry sliding. Plowing and slight abrasive wear are dominant under water lubrication. |
