Abstract
The aim of the research article is to study the mechanical and two‐body abrasive wear behaviour of glass/carbon fiber reinforced PTFE composites. The measured wear volume loss increases with increase in abrading distance. The results showed that the highest specific wear rate is for glass fiber reinforced PTFE composite with a value of 8.1×10^–6^ mm^3^/Nm and the lowest wear rate is for carbon fabric reinforced vinyl ester composite with a value of 7.2×10^–6^ mm^3^/Nm. Mechanical properties were evaluated and obtained values are compared with the wear behaviour. The worn surface features have been examined using scanning electron microscope (SEM). Photomicrographs of the worn surfaces revealed higher percentage of broken glass fiber as compared to carbon fiber.
