Kuvars dolgulu polyester kompozitlerin aşınma özelliklerinin araştırılması

Kuvars dolgu malzemeli polyester kompozitlerin aşınma olayında ağırlık kaybı ve aşınma direnci incelenmiştir. Aşınma makinesinde numuneye uygulanan yük sistemi, numunenin yüzeyine yatay olarak baskı yapan bir çelik plakada bağlı bir aşındırıcının doğrusal gidip gelme hareketi yaparak, kompozit yüzeyine sürtünmesiyle çalışır. Çalışma yükleri 10, 20 ve 30 N’dur. Uygulanan süreler 10, 20, 30, 40, 50 ve 60 dakika‘dır. Deneyler sonucunda artan yük ve süre ile ağırlık kayıplarının arttığı belirlenmiştir. Kompozit tiplerinden B, düşük ağırlık kaybı ve büyük aşınma direncine sahip olmuştur. B kompozit tipi için ağırlık kaybı ve aşınma direnci en büyük değerleri sırasıyla 0,1949 g ve 4,4334 Nm/m3 olmuştur.

Anahtar Kelimeler:

Aşınma deneyi, aşınma direnci, sürtünme katsayısı, polimer matris, kompozitler
