Effect of Fiber Type, Load, Sliding Speed and Distance on Abrasive Wear of Glass and Carbon Fiber Reinforced Composites

Öz

Today, glass and carbon fiber reinforced composites have a wide range of applications in many engineering fields. In this work, abrasive wear in dry sliding conditions of glass and carbon fiber reinforced composite bars has been carried out. In the experiments, which conducted on the pin on disc device, the influence of the fiber type, the applied load(5, 10 and 15 N): the sliding speed(0.4, 0.6 and 0.8 m/s) and the sliding distance(250, 500 and 750 m) on the tribological behaviour of the composites was investigated. As a result of the studies, it was determined that the coefficient of friction of glass fiber reinforced composite was lower than the coefficient of friction of carbon fiber reinforced composite. In mass loss depending on wear, mass loss in the glass fiber was found to be less for all conditions. It has been found that increasing load, sliding speed and distance increased mass loss. The highest mass loss for glass and carbon fiber reinforced composites were achieved with the load of 15 N, the sliding speed of 0.8 m/s and the sliding distance of 750 m.

Cam ve Karbon Elyaf Takviyeli Kompozitlerde Elyaf Cinsinin, Yükün, Kayma Hızı ve Mesafesinin Abrazif Aşınmaya Etkisi

Öz

Günümüzde, cam ve karbon elyaf takviyeli kompozitler birçok mühendislik alanında geniş bir uygulama alanına sahiptir. Bu çalışmada, cam ve karbon elyaf takviyeli kompozit çubukların kuru kayma koşullarındaki abrazif aşınmaları gerçekleştirilmiştir. Pin on disk cihazında gerçekleştirilen deneylerde elyaf türünün, uygulanan yükün (5, 10 ve 15 N), kayma hızının (0.4, 0.6 ve 0.8 m/s) ve kayma mesafesinin (250, 500 ve 750 m) kompozitlerin tribolojik davranışlarına etkisi araştırılmıştır. Yapılan çalışmalar neticesinde cam elyaf takviyeli kompozitlerdeki sürtünme katsayısının karbon elyaf takviyeli kompozitlerdeki sürtünme katsayısından daha düşük çıktığı belirlenmiştir. Aşınmaya bağlı kütle kayıplarında, bütün koşullar için cam elyafta kütle kaybının daha az olduğu görülmüştür. Artan yük, kayma hızı ve mesafesinin kütle kaybını arttırdığı tespit edilmiştir. Karbon ve cam elyaf takviyeli kompozitlerde en yüksek kütle kayıpları, 15 N yük, 0.8 m/s kayma hızı ve 750 m kayma mesafesinin uygulandığı durumlarda gerçekleşmiştir.
