The reinforcement of natural fibre and fillers in polymer resin is the latest trend followed by research groups and industries for the development of sustainable composites. Basalt fibre and waste marble powder are naturally occurring substances used to enhanced polymer properties. The present research examined the effect of both basalt fibre and waste marble powder in epoxy resin. The hand lay-up method was employed to fabricate the composite and test for mechanical and wear behaviour. The tensile, flexural, and impact energy were enhanced up to 7.5 wt. % of WMP, and the Vickers hardness of epoxy enhanced every state of reinforcement of WMP. The specific wear rate was observed to be increased with the addition of WMP until 7.5 wt. %. Scanning electron microscopy was performed to examine the nature of fractured surface wear phenomena.

在聚合物树脂中增强天然纤维和填料是研究团队和行业为开发可持续复合材料所遵循的最新趋势。玄武岩纤维和废弃大理石粉是用于增强聚合物性能的天然物质。本研究考察了玄武岩纤维和废弃大理石粉对环氧树脂的影响。采用手糊成型法制备复合材料，并测试其力学和磨损性能。当废弃大理石粉含量高达7.5 wt.%时，拉伸强度、弯曲强度和冲击能量得到提高，并且在废弃大理石粉增强的各个阶段，环氧树脂的维氏硬度均有所提高。观察到，在添加废弃大理石粉至7.5 wt.%之前，比磨损率随其添加量的增加而增大。通过扫描电子显微镜来研究断裂表面磨损现象的本质。
