摘　　要：采用模塑成型法制备氰酸酯树脂(CE)/纳米碳化硅(nm-SiC)复合材料,通过磨损率和摩擦系数测试探讨了nm-SiC对CE耐磨性能的影响,并通过扫描电子显微镜(SEM)分析探讨了其磨损机理。结果表明,nmSiC的质量分数为1.00%时,CE/nm-SiC复合材料的磨损率最低,相对于纯CE降低了51.16%,稳定摩擦系数降低了17.95%,磨损机理为轻度磨粒磨损和犁沟磨损。The cyanate ester resins（ CE）/nm- SiC composites were prepared by moulding method. The influence of the nm - SiC on the wear resistance of the composites was investigated by the testings of frictional coefficient and wear rate. The wear mechanism was discussed by SEM analysis. The result showed that the wear rate of CE/nm - SiC composites with 1.00% nano - SiC was the minimum and decreased by 51.16% compared with that of pure CE. The fric- tional coefficient was decreased by 17. 95%. The mild abrasive wear and ploughing were the main wear mechanism.
