Abstract
The present work is aimed to experimentally determine the mechanical properties such as Rockwell Hardness Number (RHN), tensile strength and two parameters of Weibull distribution curve (i.e. Weibull shape and characteristic life parameters) of fatigue life for the Poly Tetra Fluoro Ethylene (PTFE) material. The ultimate stress of PTFE specimen is determined using tensometer and its shape parameter and characteristic life are determined from rotary test bending machine. The PTFE specimen is also tested for wear and friction performance on pin-on-disc test rig. Based on the hardness test, RHN of PTFE was found to be 57 and its ultimate engineering stress was observed to be 20.5N/mm2. The Weibull shape parameter and characteristic life of PTFE specimen were observed to be 13.33 and 6734.5 cycles respectively. From the wear test result the sliding speed was found to have maximum influence on wear volume followed by sliding distance where as the load has least influence. .
