Effect of Aluminium Oxide Filler Composition on Thermoplastic Polymer

Abstract

Polymers are being used in many industrial applications. Among them PTFE is very popular as it is a self-lubricating material. In this work it is combined in different percentages of weight with alumina (0,5,10,15,20). Samples were prepared by powder metallurgy technique. Wear tests were performed for various loads of 20,30,40 N with varying percentages of reinforcement and at two speeds of 170rpm and 190 rpm. Shore D hardness was measured for different samples. From the experimentation it was found that less wear volume and friction force was registered at 15% and 20% reinforced composites respectively, whereas high toughness was observed at 15% reinforcement.
