Performance Properties of Epoxy Resin Modified with Few-Layer Graphene Obtained by the Method of Self-Propagating High-Temperature Synthesis

This study presents the results of an investigation into the influence of few-layer graphene, produced by self-propagating high-temperature synthesis from various types of biopolymers (glucose, cellulose, and lignin), on the mechanical, thermophysical, and tribological properties of epoxy resin. It was found that the addition of few-layer graphene at concentrations of up to 1 wt.% leads to an increase in compressive strength by up to 40%, flexural strength by up to 15%, and thermal conductivity by up to 40% compared to the original resin. A fivefold increase in the wear resistance of the composites was also observed compared to pure epoxy resin, due to a reduction in the friction coefficient.
