In this study, the mechanical and tribological performances of pure nylon 6 polymer and nylon 6 polymer-based composites filled with graphite at different ratios were investigated. Composites filled with graphite filler at different ratios of 5-10-15 wt% were produced. Granules were produced by compound production method, while mechanical and tribological test specimens were moulded by injection moulding method. The mechanical properties of the composites such as hardness, tensile strength, % elongation at break and modulus of elasticity and tribological properties such as coefficient of friction and wear rate were investigated. Tribological tests were carried out at a sliding speed of 0,5 m/s and a load of 30 N. Tribological properties were carried out in the case of nylon 6/nylon 6 pair, nylon 6-5Gr/ nylon 6-5Gr, nylon 6-10Gr/ nylon 6-10Gr and nylon 6-15Gr/ nylon 6-15Gr composite pairs working on each other. While increases in tensile modulus and hardness were observed, tensile strength and % elongation at break values decreased. The highest tensile modulus of 4607 MPa and the highest hardness of 77 Shore D were obtained in nylon 6 composite with 15wt.% graphite filler. The lowest tensile strength and % elongation at break values, the lowest wear rate and the highest coefficient of friction were obtained in nylon 6 polymer composite with 15% graphite filler. The friction coefficient of the nylon 6-15Gr/nylon 6-15Gr composite increased by approximately 63.8% compared to the nylon 6/nylon 6. Compared to Nylon6/nylon6, the wear rates of nylon6-5Gr/nylon6-5Gr composite, nylon6-10Gr/nylon6-10Gr composite and Nylon6-15Gr/nylon6-15Gr composite were reduced by 30.8%, 51.7% and 56.3%, respectively.

Bu çalışmada saf naylon 6 polimeri ile farklı oranlarda grafit (Gr) katkılı naylon 6 polimer esaslı kompozitlerin mekanik ve tribolojik performansları incelenmiştir. Ağırlıkça %5-10-15 gibi farklı oranlarda grafit katkılı kompozitler üretilmiştir. Granüller kompound üretim yöntemiyle üretilirken mekanik ve tribolojik test numuneleri enjeksiyonla kalıplama yöntemiyle basılmıştır. Üretilen kompozitlerin sertlik, çekme mukavemeti, kopmadaki % uzama ve elastiklik modülü gibi mekanik özellikleri ile sürtünme katsayısı ve aşınma oranı gibi tribolojik özellikleri incelenmiştir. Tribolojik deneyler, 0,5 m/s kayma hızında ve 30 N yükte gerçekleştirilmiştir. Tribolojik özellikler naylon 6/naylon 6 çifti, naylon 6-5Gr/naylon 6-5Gr, naylon 6-10Gr/naylon 6-10Gr ve naylon 6-15Gr/naylon 6-15Gr kompozit çiftlerinin birbiri üzerinde çalışması durumunda gerçekleştirilmiştir. Çekmedeki elastiklik modülü ve sertlikte artışlar gözlenirken çekme mukavemeti, kopmadaki % uzama değerlerinde azalma tespit edilmiştir. En yüksek elastiklik modülü 4607 MPa ve en yüksek sertlik 77 Shore D değeri ile %15 oranında grafit katı yağlayıcı katkı içeren Naylon 6 polimer kompozitinde elde edilmiştir. En düşük çekme mukavemeti ve kopmadaki % uzama değerleri ile en düşük aşınma oranı ve en yüksek sürtünme katsayısı %15 grafit katkılı naylon 6 polimer kompozitinde elde edilmiştir. Naylon 6-15Gr/naylon 6-15Gr kompozit çiftinin sürtünme katsayısı naylon 6/naylon 6 çiftine göre yaklaşık %63,8 oranında artmıştır. Nylon6/nylon6 ile karşılaştırıldığında, nylon6-5Gr/nylon6-5Gr kompozitin, nylon6-10Gr/nylon6-10Gr kompozitin ve Nylon6-15Gr/nylon6-15Gr kompozitin aşınma oranları sırasıyla %30,8, %51,7 ve %56,3 azalmıştır.
