采用功能剪裁技术进行混杂设计,制备了SiC颗粒/高密度聚乙烯纤维/环氧树脂超混杂复合材料(super-hybridcompositematerials,SHCM),并就功能层中SiC含量对SHCM材料力学性能、磨损性能的影响进行了实验研究。结果表明,功能层中的SiCr的质量分数为50%时,SHCM不仅有较好的力学性能,而且具有优良的耐磨损性能,其体积磨损率仅为环氧玻璃钢的4.12%,与A3钢相当。扫描电镜和理论分析说明,SHCM具有优良耐磨损性能的主要原因是功能层中的SiC颗粒作为硬质点,起到了抵抗磨损和基本变形产生磨损的双重作用,并有效地减缓了粘着磨损。
SiC / HDPE / epoxy super hybrid composites (SHCM) were prepared by the functional tailoring technique. The effects of SiC content in the functional layer on the mechanical properties and wear properties of the SHCM Impact of the experimental study. The results show that when the mass fraction of SiCr in the functional layer is 50%, SHCM not only has good mechanical properties, but also has excellent wear resistance. The volumetric wear rate of SHCM is only 4.12% of that of epoxy glass, and A3 steel quite. Scanning electron microscopy and theoretical analysis show that the main reason for the excellent wear resistance of SHCM is that the SiC particles in the functional layer act as hard points and serve the dual role of resisting wear and basic deformation, and effectively reducing the adhesive wear.
