Elektrik sektöründe kullanma amaçlı gerçekleştirilen bu çalışmada ağırlık olarak % 20 oranında kaya yünü mineral elyaf (KYME) ve mika takviyeli poliamid-6 (PA-6) termoplastik esaslı polimer kompozitler, termoset esaslı kompozit disk yüzeyine karşı aşınma ve sürtünme davranışları incelenmiştir. Çalışmanın amacı elektrik sektörü için aşınma direnci daha iyi olan polimer kompozit malzeme ile termoset doymamış polyester kompozit çiftini belirlemektir. Tribolojik deneyler disk üzerinde pim düzeneği bulunan bir aşınma cihazında gerçekleştirilmiştir. Karşı disk malzeme olarak ağırlık olarak % 40 kalsiyum karbonat ve % 25 oranında uzun cam elyaf takviyeli doymamış polyester kompozit malzemesi kullanılmıştır. Tribolojik testler, 0,5 m/s kayma hızında 0,707, 1,415, 2,123 ve 3,538 MPa basınç altında gerçekleştirilmiştir. Yapılan tribolojik çalışmalar sonucunda en düşük aşınma oranı 1.98x10-14 m2/N değeri ile %20 oranında mika takviyeli PA-6 kompozitinde elde edilmiştir. Mika takviyeli PA-6 kompoziti kaya yünü mineral elyaf takviyeli kompozite göre yaklaşık olarak % 42 oranında daha az aşındığı belirlenmiştir. Yapılan çalışma sonucunda elektriksel uygulamalarda kullanım amaçlı üretilen kompozit malzemelerden % 20 mika takviyeli PA-6 kompoziti ile %40 kalsiyum karbonat ve % 25 oranında uzun cam elyaf takviyeli doymamış polyester kompozit malzeme çifti elektrik kontak kesicilerde kullanılabilecek en uygun malzeme olarak tespit edilmiştir.

In this study carried out for use in the electricity industry, 20 % by weight of rock wool mineral fiber and mica reinforced polyamide-6 (PA-6) thermoplastic based polymer composites were investigated against the thermoset-based composite disc surface. The aim of the study is to determine the polymer composite with better wear resistance and thermoset unsaturated polyester composite pair for the electricity sector. Tribological experiments were carried out on a pin-on-disc wear test apparatus. 40 wt.% calcium carbonate and 25wt.% long glass fiber reinforced unsaturated polyester composite material were used as a counter disc material. Tribological tests were carried out at sliding speed of 0.5 m/s and under the pressure of 0.707, 1.415, 2.123 and 3.538 MPa. As a result of the tribological studies, the lowest wear rate was obtained in PA-6 composite with 20 wt.% mica with the value of 1.98x10-14 m2/N. Mica reinforced PA-6 composite was found to be approximately 42 % less wear than rock force mineral fiber reinforced composite. As a result of the study, 20 wt.% mica reinforced PA-6 composite, which is produced for use in electrical applications, has been determined as the most suitable material to be used in electrical contact breakers with 40 wt.% calcium carbonate and 25 wt.% long glass fiber reinforced unsaturated polyester composite material.
