Abstract

In this paper, knitted aramid fiber (AF) was used as the support, and graphene oxide (GO) was loaded on the support by the polydopamine (PDA) method. Epoxy resin (EP) was poured to obtain composite materials. The tribological and mechanical properties of the composites were tested, and the wear surface of the composites was characterized by scanning electron microscopy (SEM) and three-dimensional morphology. The results show that knitted AF can markedly improve the mechanical properties of the composites. As a two-dimensional material, GO plays an effective lubrication role, and GO effectively enhances the tribological properties of the composites. AF can reduce the wear rate of composites and improve the tribological properties of composites. During the friction process, AF and GO play a synergistic role, which can form a friction transfer film between the matrix and the friction medium, thereby avoiding direct contact between the matrix and the friction medium and improving the tribological properties of the composites. EP/AF/PDA (Dopamine hydrochloride)/GO has the best modification effect on the tribological properties of the composites. Compared with the friction coefficient of pure EP, the friction coefficient of EP/AF/PDA/GO is reduced by 48.36%, and the volume wear rate is reduced by 96.99% compared with pure EP.
