Outline of Final Research Achievements

In this study, ethylene propylene diene monomer (EPDM) rubber composites filled with rice bran (RB) ceramics particles were developed. The friction and wear properties of the composite materials were investigated under a wide range of sliding velocity and normal load conditions in water. The composite materials exhibited low friction and wear compared to monolithic EPDM rubber under a wide range of sliding velocities and normal loads. Sliding bearing using the composite materials was developed, and satisfactory friction, wear, and seal property were confirmed.
