The correlation between the mechanical properties of Fillers/Epoxy composites and their tribological behavior was investigated. Tensile, hardness, wear, and friction tests were conducted for Neat Epoxy (NE), Graphite/Epoxy composites (GE), and Data Palm Fiber/Epoxy with or without Graphite composites (GFE and FE). The correlation was made between the tensile strength, the modulus of elasticity, elongation at the break, and the hardness, as an individual or a combined factor, with the specific wear rate (SWR) and coefficient of friction (COF) of composites. In general, graphite as an additive to polymeric composite has had an eclectic effect on mechanical properties, whereas it has led to a positive effect on tribological properties, whilst date palm fibers (DPFs), as reinforcement for polymeric composite, promoted a mechanical performance with a slight improvement to the tribological performance. Statistically, this study reveals that there is no strong confirmation of any marked correlation between the mechanical and the specific wear rate of filler/Epoxy composites. There is, however, a remarkable correlation between the mechanical properties and the friction coefficient of filler/Epoxy composites.
研究了填料/环氧树脂复合材料的力学性能与其摩擦学行为之间的相关性。对纯环氧树脂（NE）、石墨/环氧树脂复合材料（GE）以及含或不含石墨的椰枣纤维/环氧树脂复合材料（GFE和FE）进行了拉伸、硬度、磨损和摩擦测试。将拉伸强度、弹性模量、断裂伸长率和硬度作为单个或综合因素，与复合材料的比磨损率（SWR）和摩擦系数（COF）进行了相关性分析。一般来说，石墨作为聚合物复合材料的添加剂，对力学性能有折衷效应，而对摩擦学性能有积极影响，而椰枣纤维（DPF）作为聚合物复合材料的增强材料，提升了力学性能，同时对摩擦学性能有轻微改善。从统计学角度来看，本研究表明，没有有力证据证实填料/环氧树脂复合材料的力学性能与比磨损率之间存在显著相关性。然而，填料/环氧树脂复合材料的力学性能与摩擦系数之间存在显著相关性。
