Cam Elyaf ve Kauçuk Katkılı PA6 Polimerinin Özelliklerinin İncelenmesi

8/PA6 polimerinin mekanik, termal ve tribolojik özellikleri üzerine cam elyaf ve kauçuk katkıların etkisi incelenmiştir. Mekaniksel ve fiziksel özellikleri belirlemek için çekme ve sertlik testleri ile termal özellikleri belirlemek için DSC analizi yapılmıştır. Tribolojik özelliklerin belirlenmesi için pin-disk cihazı kullanılmıştır. Aşınma testleri 0.5m/s ve 1.0m/s kayma hızları ile 20-40N yük aralıklarında yapılmıştır. Çalışma sonucunda, PA6 polimerine ilave edilen cam elyaf çekme dayanımını %33 oranında artırırken kauçuk ilavesi %18 oranında azaltmıştır. Cam elyaf ve kauçuk ilavesi kristallenme oranını azaltmıştır. Kayma hızının artması ile spesifik aşınma oranı artarken uygulanan yük ile birlikte azalmıştır. Artan kayma hızı ve yüke bağlı olarak sürtünme katsayısı artmıştır.

Investigation of Properties of Glass Fiber and Rubber Filled PA6 Polymer

In this study, the effects of glass fiber and rubber were investigated on the mechanical, thermal and tribological properties of PA polymer. Mechanical and physical properties of PA6 polymers were determined by tensile and hardness tests, and thermal properties by DSC analysis. Tribological properties were determined using a pin-on-disc device. Wear tests were carried out at a sliding speed of 0.5m/s and 1.0m/s, and a load of 20-40N. As a result, the glass fiber added to the PA6 polymer increased the tensile strength by 33% while the rubber addition decreased by 18%. Addition of glass fiber and rubber reduced the crystallization rate. The wear rate increased with increasing sliding speed, while the wear rate decreased with applied load. Coefficient of friction increased with increase load and sliding speed.
