Effect of kenaf particulate fillers in polymeric composite for tribological applications

The present work aims at exploring the possibility of using sustainable kenaf particles as particulate fillers and reinforcement in epoxy (KPafRE) composites. Kenaf particulate fillers of weight fractions (5–20 wt%) were used as reinforcement in the study of wear and friction performance of the composites. Adhesive dry tests were conducted on a Pin-on-Disc machine at applied loads (5–30 N) subjected to a stainless steel counterface with a sliding velocity of 2.83 m/s through sliding distances (0–6.72 km). From the findings, it was discovered that 15 wt% of KPafRE composite experienced superior in wear and frictional properties; the specific wear rate and friction coefficient was reduced by 67% and 56%, respectively, as compared to neat epoxy. Photo micrographs of the worn samples revealed that there was a significant amount of back film transfer, which assisted in enhancing the wear and frictional performance of the composites.
