Determination of Polymer and Polymer Composites with Wear Resistant for Use in Electrical Contact Breaker

Abstract

This study was carried out to determine the pair of materials with the best abrasion resistance in contact breakers in the electrical industry. Pin-on-disk wear test machine was used for tribological tests. For this purpose, 25wt.% long glass fiber reinforced and 40wt.% calcium carbonate added unsaturated polyester based thermoset composite material (25wt.%GF + 40wt.%CaCO3+UPET) was used as the disc material. As pin materials, unfilled poly-ether-sulfone (PES) polymer, 30wt.% glass fiber reinforced poly- phenylene-ether (PPE+SBS+30wt.%GF) composite and 15wt.% glass fiber reinforced poly-butylene- terephthalate/poly-ethylene-terephthalate mixture composite (PBT/PET+15wt.%GF) materials were used. Tribological experiments were carried out under dry sliding conditions and at room temperature. The experiments were carried out under pressure of 0.707, 1.415, 2.123 and 3.538 MPa and at a sliding speed of 0.5 m/s. As a result of wear and friction tests, friction coefficient and specific wear rates of materials used were determined. As a result of the experiments carried out, the highest wear rate was obtained in the unfilled PES polymer, while the lowest wear rate was obtained in PPE+SBS+30wt.%GF composite. As a result of the experiments carried out, PPE + SBS+30wt.%GF/25wt.%GF+40wt.%CaCO3+UPET thermoset composite pair has been determined as the most suitable material pair for use in contact breakers.

Bu çalışma, elektrik sektöründe kontak kesicilerde aşınma direnci en iyi olan malzeme çiftini belirlemek için yapılmıştır. Aşınma deneyleri için pim-disk aşınma test cihazı kullanılmıştır. Bunun için çalışmada, disk malzemesi olarak %25 oranında uzun cam elyaf takviyeli ve %40 kalsiyum karbonat katkılı doymamış polyester esaslı termoset kompozit malzeme (%25CE+%40CaCO3+UPET) kullanılmıştır. Pim malzemeler olarak ise, katkısız poli-eter-sülfon (PES) polimeri, stiren-butadien-stiren elastomer katkılı ve %30 cam elyaf takviyeli poli-fenilen-eter (PPE+SBS+%30CE) kompoziti ve %15 cam elyaf takviyeli poli-butilen-tereftalat/poli-etilen-tereftalat karışımı kompozit (PBT/PET+%15CE) malzemeleri kullanılmıştır. Tribolojik deneyler, kuru kayma şartları altında ve oda sıcaklığında gerçekleştirilmiştir.Deneyler, 0,707, 1,415, 2,123 ve 3,538 MPa basınç altında ve 0,5 m/s kayma hızında yapılmıştır. Aşınma ve sürtünme deneyleri sonucunda, malzemelerin sürtünme katsayısı ve spesifik aşınma hızları belirlenmiştir. Gerçekleştirilen deneyler sonucunda, en yüksek aşınma hızı katkısız PES polimerinde elde edilirken en düşük aşınma hızı ise PPE+SBS+%30CE kompozitinde elde edilmiştir. Gerçekleştirilen deneyler sonucunda kontak kesicilerde kullanmak için PPE+SBS+%30CE/%25CE+%40CaCO3+UPET termoset kompozit çifti en uygun malzeme çifti olarak belirlenmiştir.
