In this study, new polymer composites filled with RB ceramics particulate (polymer/RB ceramics composites) was developed, and their friction and wear properties were experimentally investigated. The weight fraction of RB ceramics particulate was greater than 50 wt% for each resin. The polymer/RB ceramics composites showed lower friction and lower wear than neat resins (PA66, PA11, PBT, POM, PP) under dry and oil lubricated conditions. Particularly, a remarkable reduction of specific wear rate was obtained for the newly developed composites as compared with the neat resins under dry condition (67-98% reduction) or oil lubricated condition (68-99% reduction).
