Hard particulate fillers are used to improve the mechanical and tribological properties of thermoplastic resins. This study investigated the fundamental tribological behavior of polyamide 66 (PA66) resin composites containing rice bran ceramics (RBC) particles or glass beads (GBs) at a wide range of normal loads and sliding velocities under dry condition, and the utility of hard particulate fillers as a low-friction and high-wear-resistant filler is discussed. PA66/RBC and PA66/GB composites showed low friction and low wear compared with pure PA66, particularly at a low sliding velocity. Based on observations of the worn surfaces, RBC particles and GBs prevented the formation and growth of roll-shaped particles on the wear track at low sliding velocities, resulting in low wear. In addition, regarding the wear of the counterpart material, RBC particles are less aggressive than GBs.
