Polietereterketon ve Kompozitlerinin Polyester Matrisli Termoset Kompozit Malzemesine Karşı Aşınma ve Sürtünme Performanslarının İncelenmesi.

This study aims to find the best wear resistant polymer or polymer composite pair that can be used in electrical contact breaker applications. For this, the pin-on-disc (PoD) wear test machine was used. Poly-etherether- ketone (PEEK) polymer and 20% and 30% by weight glass fiber (GF) reinforced PEEK composites were used as pin material. Long glass fiber reinforced and calcium carbonate mineral-filled unsaturated polyester composite material was used as the counterpart material. In the tribological experiments, while the effect of glass fiber reinforcement on wear was examined, the effect of the applied pressure was also investigated. The highest wear rate was obtained in PEEK+30% GF polymer composite with 4.42x10-14 m2 N-1 under 5.30 MPa pressure, while the lowest wear rate was obtained with 1.13x10-14 m2 N-1 under 1.77 MPa pressure. As a result of the study, it was determined that among the materials subjected to the wear test, the long glass fiber reinforced and calcium carbonate filled pure polyester composite material and the pure PEEK polymer pair were the most suitable pairs for electrical contact breaker applications.
