Abstract

In this study, the wear and friction performances of polyamide 66 (PA66) polymer and 10wt%, 20wt% and 30wt% carbon fibre (CF) reinforced polyamide 66 composites were investigated. Wear tests were carried out against a steel disc under dry ambient conditions. Carbon fibre reinforced PA66 composite was produced as granules in a twin screw extruder and then wear test specimens were molded in an injection molding machine. The wear tests were performed under 20-30-40N loads at sliding speeds of 0,4, 0,8 and 1,2 m/s. The tests were accomplished at ambient temperature using a pin-on-disc abrasion tester. At 0,8 m/s sliding speed and 30N load, 10%, 20% and 30% CF added to PA66 polymer reduced the coefficient of friction by 12,4%, 23,5% and 32,7%, and the wear rates by 19,9%, 38,9% and 82,0%. While the coefficient of friction and wear rate increased with the raise of the applied load and sliding speed. In general, the wear rates of PA66 and PA66/CF composites were obtained as 10-10 mm3/Nm. The correlation coefficient (R2) between wear rate and friction coefficient was obtained as 0,9686 for PA66 polymer and 0,775 for PA66/30CF composite. In the tribological test working conditions applied, it was determined that carbon fibre reinforced PA66 with 30 % carbon fibre reinforcement was 82% resistant on average than PA66 polymer.

KARBON FİBER KATKILI POLİAMİT 66 POLİMER KOMPOZİTLERİN TRİBOLOJİK ÖZELLİKLERİNİN DEĞERLENDİRİLMESİ

Abstract

Bu çalışmada, poliamit 66 (PA66) polimeri ile ağırlık olarak % 10, %20 ve %30 oranlarında karbon elyaf (KE) takviyeli poliamit 66 kompozitlerinin aşınma ve sürtünme davranışları incelenmiştir. Aşınma deneyleri çelik diske karşı kuru ortam şartları altında gerçekleştirilmiştir. Karbon elyaf katkılı PA66 kompozitleri çift vidalı ekstruderde granül olarak üretilmiş sonrasında enjeksiyon makinesi ile aşınma test numuneleri basılmıştır. Aşınma testleri 0,4, 0,8 ve 1,2 m/s kayma hızlarında, 20, 30 ve 40N yükler altında yapılmıştır. Deneyler, ortam sıcaklığında pim-disk aşınma cihazında gerçekleştirilmiştir. 0,8 m/s hız ve 30N yükte, PA66 polimerine ilave edilen %10, %20 ve %30 oralarındaki KE, sürtünme katsayısını %12,4, %23,5 ve %32,7 oranında, aşınma oranlarını ise %19,9, %38,9 ve %82,0 oranında azaltmıştır. Artan yük ve hız ile sürtünme katsayısı ve aşınma oranı artmıştır. Genel olarak, PA66 ve PA66/KE kompozitlerin aşınma oranları 10-10 mm3/Nm olarak elde edilmiştir. Aşınma oranı ve sürtünme katsayısı arasındaki korelasyon katsayısı (R2) PA66 polimeri için 0,9686, PA66/30KE kompozitin için ise 0,775 olarak elde edilmiştir. Uygulanan tribolojik test çalışma şartlarında % 30 oranında karbon elyaf takviyeli PA66 kompozitin katkısız PA66’ya göre ortalama %82 oranında dirençli olduğu belirlenmiştir.
