In the oil less reciprocating compressor, it is not necessary for lubricating oil to be fed into a piston ring, a piston or a cylinder. Lubricating oil is not introduced into a compression chamber in the cylinder, and is not contained in compressed air discharged from the compressor. Thus, oil less reciprocating air compressors are widely used in medical, food, chemical, textile or oxygen feeding field that do not like oil compressed air, or among users who are troubled in feed and maintenance of lubricating oil. Now a day’s pure PTFE (polytetrafluoroethylene) is widely used as a piston ring material which is self-lubricating and subjects to lower coefficient of friction, but problem with PTFE is that, it subjects to high wear rate, which can be reduced by adding suitable fillers. In this study, polyetheretherketone (PEEK) is taken as a base polymer material, and PTFE used as a solid lubricant. These polymer materials reinforced with glass fibers (GF) and additives like MoS2, Bronze. The effects of time, load, sliding velocity and filler content in PEEK/PTFE are experimentally examined. A comparative analysis of five composites (1) PEEK, (2) 70%PEEK/15%PTFE/15%glassfibers, (3) 65%PEEK/15%PTFE/15%GF/5%MoS2, (4) 50%PEEK/15%PTFE/15%GF/5%MoS2/15%BRONZ, (5) 45%PEEK/15%PTFE/15%GF/5%MoS2/20%BRONZ is presented showing how properties of PEEK can be improved by addition of filler content. The results of experiments are proving that the wear is strongly influenced by the composition of filler content. It was found that, in PEEK/PTFE addition of glass fibers with MoS2 shows the higher wear resistance. Also while increasing the percentage of BRONZ in polymer composite resist the wear rate.
