Polimer Kompozit ve Çelik Diske Karşı Cam Elyaf Takviyeli Poli-Eter-Eter-Keton (PEEK) Kompozitin Aşınma Özellikleri

Bu çalışmada, %30 cam elyaf (CE) katkılı poli-eter-eter-keton (PEEK) polimerinin termoset poliester kompozit ve AISI 316L paslanmaz çelik diske karşı kuru ortam şartları altında sürtünme ve aşınma özellikleri incelenmiştir. Sürtünme ve aşınma çalışmaları pim-disk aşınma test cihazı ile gerçekleştirilmiştir. Aşınma ve sürtünme testleri 0.5m/s kayma hızında ve 20, 40 ve 60N yük altında yapılmıştır. Çalışma sonucunda, her iki disk için uygulanan yükün artması ile PEEK/30CE kompozitin sürtünme katsayısı ve aşınma oranı artmıştır. En düşük sürtünme katsayısı ve aşınma oranı, sırasıyla 0.24 ve 3.31x10-15 m2/N değerleri ile 20N yük altında AISI 316L paslanmaz çelik disk kullanıldığında elde edilmiştir.

Wear Behaviours of Glass Fiber Reinforced Poly-ether-ether-ketone Composite (PEEK) Versus Polymer Composite and Steel Counterparts

In this study, the friction and wear behaviors of 30wt.% glass fiber reinforced poly-ether-ether-ketone (PEEK) have been studied versus thermoset polyester composite and AISI 316L SS steel counterparts under dry sliding conditions. Friction and wear studies were carried out using a pin-on-disc wear test rig. Friction and wear tests were run at 0.5m/s sliding speed and under the applied load of 20, 40 and 60 N. The results show that the coefficient of friction and specific wear rate of glass fiber reinforced PEEK composites increased with increasing applied load for both of discs. The lowest coefficient of friction and specific wear rate were obtained when using AISI 316L SS steel disc under 20N load with a value of 0.24 and 3.31x10-15 m2/N, respectively.
