Modification of Graphene and Friction and Wear Property of its Epoxy Resin Matrix Composites
Abstract
(KH-graphene) to produce KH-graphene/epoxy resin composites, and the effect of KH-graphene content and load on the friction
and wear property of the composites was studied. The results showed that the KH560 was successfully grafted to the surface of
graphene; The KH-graphene decreased the mass loss and friction coefficient of the epoxy resin, and with increasing the KHgraphene content, the mass loss and friction coefficient of KH-graphene/epoxy resin composites both showed a decreasing trend,
and when the load was 150N, KH-graphene content was 0.5%, the mass loss and friction coefficient of composites were reduced
by 44.9% and 17.4%; With increasing the load, the mass loss and friction coefficient of KH-graphene/epoxy resin composites
also showed a decreasing trend; The wear form was mainly fatigue wear under the low load, and KH-graphene could inhibit the
generation and expansion of micro-cracks; After the load increased, the wear form was mainly abrasive wear; After the graphene
added, the wear scar of the worn surface of composites was relatively reduced.
