The purpose of this study is to investigate the influence of nut shell powder (NSP) content on the tribological properties of recycled polyolefin (R-PO) composites. NSP was previously grinded the dried nut shell by crusher machine cryogenically in liquid nitrogen. NSP/R-PO composites with NSP content of 5, 10 and 20 vol.% were prepared in this study. These composites were extruded by a twin screw extruder and injection-molded. Their tribological properties were measured by a reciprocating type sliding wear tester at constant normal load and sliding speed under dry condition. It was found that NSP is effective for reducing the wear resistance of R-PO, and the influence of NSP content on the tribological properties of NSP/R-PO composites does not remarkably appear, but they are improved with the addition of low content such as 5 vol.%. This may be attributed to the change of wear mechanism according to the filling of NSP.
