| Outline of Final Research Achievements |
The objective of this study was to clarify the effect of the self-lubrication film and formation of the PEEK composite film. Rolling contact test was carried out by using Hybrid radial PEEK bearing with surface defects. It was found that the size of the surface defects was decreased by accumulation of the PEEK composite film.
This result shows the possibility of suitable tribological contact surface and knowledge to control the self-lubrication film of PEEK composite for long life of polymer mechanical element.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果では，PEEK樹脂機械要素の自己潤滑膜の制御と長寿命化に影響を及ぼす表面キズを無害化できる可能性を示した．微細溝を有する軸受軌道面にグラファイトのナノ粒子を含んだ自己潤滑膜が生成したことを発見した．自己修復機能を持つ樹脂機械要素として低摩擦と長寿命化が期待でき，材料損失や故障リスクが減り省資源化にも貢献できる．今後，気液潤滑下など特殊環境用としてハイブリッド樹脂機械要素の長寿命化技術に発展させ，エネルギー機器材料分野などに適用域を拡げ応用が期待される．
