Friction Wear of Modified Epoxy Composites

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, polyethylene polyamine curing agent, mineral powder, and fibrous reinforcement are used to form the epoxy composite material. Conditions in which friction and wear stabilize through the formation of self-assembled structures are established in tribotechnical tests. The wear rate is studied as a function of sliding speed, load, and sliding distance. The effectiveness of gradual loading of the composite during tribological interaction is shown. This allows wearresistant surface structures to be created.
