Abstract

Bu çalışmada, karbon elyaf (KE) dolgulu poliamit 6 (PA6) polimer
kompozitlerinin sürtünme ve aşınma davranışları üzerine kayma hızı ve yükün
etkileri incelenmiştir. PA6 polimeri ve PA6 kompozitlerinin sürtünme ve aşınma
testleri 1040 çelik diske karşı kuru ortamda pim-disk sistemi ile
gerçekleştirilmiştir. Tribolojik testler oda sıcaklığında, farklı yük (10-40N)
ve kayma hızı (0.4-1.2m/s) şartlarında yapılmıştır. Deneysel çalışmalar
sonucunda, tüm polimer numuneler için yükün ve kayma hızının artmasıyla
sürtünme katsayısı artmıştır. PA6 kompozitleri için aşınma oranı 10^-10
mm³/Nm civarında elde edilmiştir. PA6 polimer kompozitlerinin aşınma
oranını etkileyen en önemli parametrenin uygulanan kayma hızı olduğu
belirlenmiştir.

The Effect of Sliding Speed and Applied Pressure Values on the Wear Behaviour of Carbon Fiber Filled Polyamide 6 (Pa6) Polymers

Abstract

In this investigation, the influence of sliding
speed and load values on the friction and wear behaviour of carbon fiber filled
polyamide 6 (PA6) composites were studied. Friction and wear tests of PA 6
polymer and PA6 polymer composites versus 1040 steel were carried out at dry
condition on a pin-on-disc arrangement. Tribological tests were performed at
room temperature at different loads (10-40N) and sliding speeds (0.4–1.2 m/s).
The results showed that, for all polymers used in this investigation, the coefficient
of friction increases linearly with the increase in load and sliding speed. The
specific wear rate for PA6 composites were in the order of 10⁻¹⁰ mm³/Nm.
The most important parameter affecting the wear rate of PA6 polymer composites
was determined to be the sliding speed.
