Abstract

   In this
study, the effect of epoxy matrix composite on the wear resistance was
investigated by adding the lubricator graphite filler element in high amounts
(25-52% by volume) of epoxy matrix. Epoxy matrix composites are
produced by open molding technique. 3-point bending strength, bending modulus,
hardness and density measurements of graphite-filled composites were carried
out and microstructure developments were examined. Wear tests were carried out at room temperature under a 5N load, in a
ball-on-disc wear device up to a wear distance of 200m. The effects of physico-mechanical properties and microstructure development
on wear behavior were investigated. As a result, the best abrasion resistance
was obtained in 30% graphite added composite material.

EPOKSİ MATRİSLİ KOMPOZİTLERDE KATI YAĞLAYICI İLAVESİNİN SÜRTÜNME KAYBININ AZALTILMASINA ETKİSİNİN İNCELENMESİ

Abstract

   Yapılan
çalışmada yağlayıcı özelliği bulunan grafit dolgu elemanının yüksek miktarlarda
(hac.%25-52) epoksi matris içerisine ilave edilmesiyle epoksi matrisli
kompozitin aşınma direnci üzerine etkisi araştırılmıştır. Epoksi matrisli kompozitler
açık kalıplama tekniği ile üretilmiştir. Grafit dolgulu kompozitlerin 3 noktalı
eğme mukavemeti, eğme modulü, sertlik, yoğunluk ölçümleri yapılmış ve mikroyapı
gelişimleri incelenmiştir. Aşınma testleri 5N yük altında, 200m aşınma
mesafesine kadar ball-on-disk aşınma cihazında, oda sıcaklığında
gerçekleştirilmiştir. Fiziko-mekanik özelliklerin ve mikroyapı gelişiminin
aşınma davranışı üzerine etkisi araştırılmıştır. Sonuç olarak en iyi aşınma
direnci %30 grafit katkılı kompozit malzemede elde edilmiştir.
