Sliding wear resistance of epoxy polymers against stainless steel

Conference Paper


Abstract


  • The wear mechanisms occurring during sliding contact between epoxy resins and a smooth steel counterface have been investigated. The samples were prepared from a commercial diglycidyl ether of bisphenol A epoxy and cured with various hardeners. The cured resins displayed a wide range of mechanical properties (particularly fracture toughness), and crosslink densities. The wear rates of the samples were found to vary by up to four orders of magnitude. It was found that the wear rates correlated to the inverse of the fracture toughness, which was in accord with previous studies on the wear of plastics by Omar et al. The mechanism was found to involve an `adhesive/fatigue' process, as proposed by Omar. Additionally, it was found that the addition of a rubber toughening agent had no effect on the wear rate, whilst sliding contact between polymer and polymer resulted in a much higher rate of wear. Possible explanations for these behaviour are given.
