Wear of Modified Epoxy Composites under Friction

Abstract

Tribotechnical composites based on epoxy oligomers are used to benefit from special properties of epoxides showing high moldability, adhesion ability, and corrosion resistance and low shrinkage. Epoxy resin ED-20, curing agent polyethylene polyamine, and mineral powder and fibrous fillers are used to form epoxy composite material. Conditions in which friction and wear stabilize through formation of a self-assembled structure are established in tribotechnical tests. The wear rate is studied as a function of speed, load, and friction path. The effectiveness of gradual loading of the composite during tribological interaction is shown. This allowed a wear-resistant surface structure to be created.
