Thermal Effect on Mechanical and Tribological Performance of Polyether-Ether-Keton

The present work describes the development of polymer composites consisting of Polyether-ether-keton (PEEK). This work reports the wear performance evaluation of a new class of PEEK. The effects various range of temperatures on the tribological properties of PEEK composites were studied under dry friction conditions. PEEK composites are maximum used as compressor piston rings or valve for their outstanding mechanical and thermal performance at harsh operating conditions, where PTFE composites fail to service. However high wear rate and friction coefficient of pure PEEK limitation its wider use. Maximum researchers found that PEEK is good in mechanical characteristic but inferior performances of tribological properties. The effect on the friction and wear nature of PEEK polymer composites has been improved, at room temperature. There are various operations performed in industry at elevated temperature on different machines and high wear rate at maximum temperature is a serious problem in a large number of industrial applications. The objective of this work to study the friction and wear properties of PEEK elevated temperature as well as to increase tribological properties of PEEK without loss of mechanical properties at elevated temperature.
