| Outline of Final Research Achievements |
Wear resistance of epoxy resins were improved by incorporation of graphitic nanoparticles at relatively low amount of 1 mass%. The transfer of epoxy resin to the friction counter face of steel surfaces decreased by the addition of nanoparticles, which can contribute to the wear resistance. Additionally, the low friction property of nanoparticles can reduce friction force. The detailed mechanisms should be studied for the breakthrough of the resin materials used in the sliding mechanical parts in severe conditions.
