Study on Mechanical Properties of Multilayer Graphene/Epoxy Nanocomposites

Abstract:

In this paper, the implementation and testing of multilayer graphene/epoxy resin nanocomposites are discussed. Firstly, the epoxy resin hardener is mixed with the multilayer graphene, and then mixed with the main agent, then poured into the mold, and the low temperature cooling system is used. The curing time of the epoxy resin is slowed down, and the bubble is removed before the complete hardening by the vacuum defoaming method, and the mechanical properties such as tensile strength and toughness are compared with the pure epoxy resin after being sufficiently hardened. In this paper, we investigated the effect of multilayer graphene content on mechanical properties by using the tensile test and impact test. We discussed the effect of multilayer graphene content on the coefficient of elasticity of the multilayer graphene/epoxy resin composites at different stretching rates. And the toughness of the multilayer graphene/epoxy resin composites was evaluated by impact test. After the experiment, it was found that the stretching rate has a certain degree of influence on the grapheme/epoxy resin composite material. And that the addition of 2% multilayer graphene to epoxy resin had the best effect and could effectively improve the coefficient of elasticity and toughness.
