| Outline of Final Research Achievements |
The addition of nanocarbons to base resin improved high-temperature wear resistance of resin. The degradation of wear resistance at high temperature decreased less than 1/10. Although the mechanism of the improvement of wear resistance was not yet clear, it was expected that the nanoparticles reduced the frictional heat generation by providing lubrication and suppressed the temperature rise at the friction interface by improving thermal conductivity of the resin.

| Academic Significance and Societal Importance of the Research Achievements |
高い伝熱性と摺動性を有するナノ粒子の樹脂への分散によって，蓄熱が生じやすい摩擦摺動下において熱伝導性と摺動性の向上による摩擦メカニズムが明らかになった．一方，高温環境下での耐摩耗性を大きく向上できる繊維強化複合材料に高温耐摩耗性を付与できれば，摺動部材にも適応範囲が広がり，機械部材の軽量化に貢献できる．
