Özet:

 In this study, the effect of the amount of short carbon fibers SCFs on the mechanical and tribological properties of polyester PES composite were investigated. Composites were produced with different weight fractions 0.5, 1, and 2 of SCFs by the hand lay-up method. The flexural strength and flexural modulus of samples was studied by conducting 3-point bending tests, whereas the energy-absorbing performance was examined by performing the Izod impact test. Moreover, the wear resistance properties of samples were measured by applying a 20 N load. The scanning electron microscope was used to examine the morphology of broken and worn surfaces of specimens. Test results exhibit the flexural strength and flexural modulus of SCFs reinforced polyester composite was decreased with the increment of fiber contents. However, the same trend was not observed for the impact test. Thus, the addition of 2 wt.  SCFs onto pure polyester improves the energy absorbing of pure polyester nearly by 210. The present study also reveals the wear resistance properties of SCFs reinforced polyester composites are indirectly related with of SCFs content. Hence, the highest wear resistance capacity was observed for PES0.5CF of about 1.5110-3 mm3m. Therefore, the addition of small amounts of SCFs onto pure polyester attributes significant effects in tribological behaviors compared to mechanical properties.

 Bu çalışmada, kısa karbon elyaf SCFs içeriğinin polyester PES kompozitin mekanik ve tribolojik özellikleri üzerindeki etkileri araştırılmıştır. El yatırması yöntemiyle ağırlıkça farklı oranlarda 0,5, 1 ve 2 SCFler içeren kompozitler üretilmiştir. Numunelerin eğilme mukavemeti 3 noktalı eğilme testleri ile, darbe sönümleme performansları ise İzod darbe testi yapılarak incelenmiştir. Ayrıca numunelerin aşınma direnci özellikleri 20 N yük uygulanarak ölçülmüştür. Numunelerin kırık ve aşınmış yüzeylerinin morfolojisini incelemek için taramalı elektron mikroskobu kullanılmıştır. Test sonuçları, lif içeriğinin artmasıyla SCF takviyeli polyester kompozitin eğilme mukavemetinin azaldığını göstermektedir. Ancak, darbe dayanımı analizinde aynı eğilim gözlemlenmemiştir. Böylece, 2 SCF takviyesi ile PES2CFnin darbe dayanımını, saf polyestere göre yaklaşık 67 oranında artmıştır. Bu çalışma aynı zamanda SCF takviyeli polyester kompozitlerin aşınma direnci özelliklerinin SCF içeriği ile dolaylı olarak ilişkili olduğunu ortaya koymaktadır. Dolayısıyla, en yüksek aşınma direnci 1.5110-3 mm3m PES0.5CF numunesi için görülmüştür. Bu nedenle, saf polyester üzerine düşük oranlarda SCF içeriğinin eklenmesi, mekanik özelliklere kıyasla tribolojik davranışlarda önemli etkiler göstermiştir.
