Abstract: Epoxy resin modified by nanometric γ-alumina or multi-walled carbon nanotubes (MCNTs) was prepared with solution mixing method, and the wear resistance of the composite was studied. The results show that when an optimum amount of nanometric alumina or MCNTs is filled in epikote51 (E51), the wear resistance of the composite will increase. When 8 wt pct nanometric γ-alumina is filled in E51, the wear resistance of the composite increases to 230%. When 10% MCNTs is filled in E51, the wear resistance of the composite increases to 226%. When nanometric alumina is filled in, the wear resistance of modified epikote51 will increase as the cure temperature is heightened.
