Outline of Final Research Achievements

In the present study, we developed new composite mateirals using Rice bran ceramics (RBC) particles as a filler that can provide both low friction and high wear resistance. Polyetheretherketone (PEEK) resin/RBC composite and copper (Cu) alloy/RBC composite were developed. The PEEK/RBC composite showed low friction and low wear under water lubrication. This result indicates that the PEEK/RBC composite can be used as a sliding bearing material under water lubrication. The Cu alloy/RBC composite has been succeeded in practical use as high wear-resistant pantograph slider material for current collector of railway.
