... (such as phenolics, epoxy, etc.) may have low wear rates and higher strength than those with thermoplastics because a higher ratio of fiber is achievable with a thermoset matrix. Incorporation of fillers also can modify wear resistance of polymers up to the order of four. Solid lubricants mostly reduce wear...

If a component is not lubricated, the presence of oxide powder may not necessarily signify fretting but, rather, wear...
