Abstract

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

Abstract

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.
