摘　　要：将耐磨涂层与树脂基复合材料采用RTM工艺一体化成型,并对一体化成型复合材料的耐磨性能进行了测试分析,采用三维白光干涉表面形貌仪测试了磨损试样的表面形貌,采用激光粒度分析仪对所使用的硬质粉体进行了粒度分析,采用电子显微镜观测了耐磨复合材料的内部结构。结果表明,复合材料试样的摩擦系数与磨痕深度情况相一致,即试样的摩擦系数越小,其磨痕深度也越小。一体化成型耐磨复合材料表面涂层的连续相为树脂基体,限制了该种复合材料在高速摩擦条件下的使用。This article made a try on the prepration of abrasion-resistant composites by integrative RTM mould- ing. Wear testing of said composites was performed. Surface profiles of samples after wearing test were drawn by Phase Shift MicroXAM-3D. Granularity ansysis of hardness particle which was the main component of abrasion-re- sistant coating was conducted by laser granularity analyst. The inside microstructure of abrasion-resistant composites was observed by scanning electron microscope. The results demonstrated that the friction coefficient was coherent with ultimate indent depth, namely, the less the friction coefficient was, the less indent depth was. The use of abra- sion-resistant composites in high speed conditions could be limited because resin was the matrix of abrasion-resistant coating.
