| Outline of Final Research Achievements |
In this study, polymer composites filled with RB ceramic (RBC) particles were developed and those mechanical properties and tribological properites under water lubrication were experimentally investigated. The hardness and strength of the composites increased with decreasing RBC particle diameter. The results of sliding friction tests under water lubrication indicated that PEEK and POM composites filled with 20 vol% RBC particles with a dimater less than 5 micro-meters exhibited low friction and low specific wear rate less than 10-9 mm2/N. The value of the specific wear rate is 1/10 of that for steel/steel contact under oil lubrication (10-8 mm2/N).The results indicated that the developed composite materials have 10 times higher wear resistance than steel materials under water lubrication.

本研究は，樹脂材料において問題であった低い耐摩耗性を，米ぬかを原料とする硬質多孔性炭素材料RBセラミックス粒子との複合化により解決し，油潤滑下におけるステンレス鋼の10倍以上の耐摩耗性を有する樹脂系複合材料の開発に成功したものである．この研究成果は，従来のしゅう動材料に比べ軽量かつ水による潤滑を長期間可能にする点で学術的意義が高く，また，機械におけるしゅう動システムの環境負荷低減，省エネルギー化に大きく貢献するものであり，カーボンニュートラルの実現に寄与する点で社会的意義は非常に高いといえる．
