S. G. Varpe, R. N. Todkar, S. R. Londhe, R. R. Ligade


Experimental investigation of PTFE (Polytetrafluroethylene) composites with different filler materials such as glass fiber, molybdenum disulphide, graphite carried is out in this study. This study exhibits tribological properties such as wear and coefficient of friction of PTEF composite material. Pin on disc tribometer is used to conduct the wear on PTFF polymer composite. Test is conducted on 10 mm diameter PTFE pin against EN31 counter face. Wear and friction experiment were carried out on the pin-on-disc apparatus at ambient condition. Variables like; load 1 to 3 kg, sliding velocity 0.5 to 2 m/s, glass filled percentage, graphite percentage and molybdenum percentages were studied. In this study, a comparative analysis of three different combinations of materials studied for wear are; PTFE + 25% glass filled, PTFE + 25% glass filled + 5% graphite, PTFE + 25% glass filled + 5% molybdenumdisulphide.
