Friction and Wear Analysis of PTFE Composite Materials
Polytetrafluoroethylene (PTFE) is a very important polymer-based engineering material. The PTFE material has many applications such as in aerospace, food and beverage industry, pharmaceuticals and telecoms. In this paper, investigate the effect of sliding distance, varying load, filler content in PTFE, sliding velocity experimentally by using a pin on disc test rig. A relative analysis of three different composites usually (PTFE + 30% carbon, PTFE + 30% bronze, and PTFE + 30% glass) are presented. Commercially, pure PTFE has high wear rate in order to reduce this wear rate the experimental investigation is carried out by using pin on disc test rig under constant sliding speed and constant time of 15 min. The results revealed that pure PTFE has high wear rate than the composite PTFE materials.
