The wide applications of UHMWPE include bio-medical material for artiﬁcial joint replacement, engineering bearing, valves and automotive. Despite the suitability of UHMWPE for these applications, there are still challenges on the wear problem that occur in UHMWPE components, especially in bio-medical implant . To overcome this problem, UHMWPE composites were fabricated by adding reinforcing ﬁbres and particle ﬁllers. Wear and friction tests were performed using a pin-on-disc tester with a variable applied load sliding speed against 400-grit SiC abrasive paper counter face. Subsequently, the worn surfaces and the transfer ﬁlm formed were observed using scanning electron microscope (SEM).
