We studied the factors that affect the sliding-induced wear of polyamide 66 (PA66) composites. The dimensionless severity parameter Ssc was defined from the minimum equivalent stress in the sliding contact area and calculated by using approximations. Subsequently, we conducted the friction tests for the PA66 composites filled with hard fillers under dry conditions. The hard fillers included rice bran ceramics particles, glass beads, carbon fibers, and glass fibers. According to the relationship between the wear rate and the severity parameter, the specific wear rate increased exponentially with increasing Ssc for all the materials. Obtaining low-wear PA66 required improving the yield strength and reducing the Young's modulus and the friction coefficient.
