摘要

研究了纳米碳纳米管/石墨烯/纳米金刚石复合材料的摩擦学性能。采用维氏硬度计、表面粗糙度计和往复磨损计，分别研究了MWCNT/NDs、石墨烯/NDs和MWCNT/石墨烯增强环氧复合材料的硬度、表面粗糙度和磨损性能。采用热固性聚合物环氧树脂的对角线长度(Hv, l)和压痕深度(Hv, d)对硬度进行了评估。此外，填料通过降低摩擦系数和磨损率，大大提高了环氧树脂的耐磨性能。采用未经处理的MWCNT、石墨烯、NDs以及MWCNT/NDs、石墨烯/NDs和MWCNT/石墨烯的混合物，研究了不同填料对环氧树脂摩擦学性能的影响。填料的加入大大提高了环氧树脂的摩擦学性能。

A Comparative Study of Novel Tribological Response of Hybrid Epoxy Composites Reinforced by MWCNT/ Graphene/Nanodiamond

This paper investigates the tribological properties of MWCNT/Graphene (GnP)/ Nanodiamond (NDs) reinforced hybrid epoxy composites. In this paper, the hardness, surface roughness and wear properties of epoxy with MWCNT/NDs, Graphene/NDs, and MWCNT/ Graphene reinforced epoxy composites have been investigated using a Vicker hardness tester, surface roughness tester and reciprocating wear tester respectively. Hardness evaluated using the diagonal length (Hv, l) and by the indentation depth (Hv, d) of thermoset polymers, epoxy resin, was carried out. In addition filler, very much enhances the wear properties of the epoxy resin, by reducing the friction coefficient and wear rate. The result of different fillers on the tribological behaviour of an epoxy has been studied using untreated MWCNT, Graphene, NDs and mixture of MWCNT/NDs, Graphene/NDs and MWCNT/Graphene. Addition of filler greatly enhances the tribological properties of epoxy resin.
