Dolgusuz ve GR/B4C Dolgulu Hibrit Kompozitlerin Mekanik Özelliklerinin ve İşlenebilirliğinin İncelenmesi

Öz

Bu çalışmada B4C ve Gr dolguları kullanılarak üretilen cam elyaflı polimer kompozitlerin (CETK) çekme, eğme ve delik delme özellikleri incelenmiştir. %7,5 B4C ve %7,5 Gr dolgulu hibrit kompozitlerde dolgu parçacıkları hem çekme hem eğme dayanımlarını düşürmüştür. Çekme numunelerinin kopmuş kesitlerinin SEM görüntüleri analiz edildiğinde dolgulu kompozitlerde matris boşluklarının daha fazla olduğu belirlenmiştir. Hibrit kompozitlerden elde edilen delaminasyon değerleri dolgusuz kompozitlerden daha düşük, ilerleme kuvvetleri ise dolgusuz kompozitlerden daha yüksek çıkmıştır. Kesme hızı arttıkça delaminasyon değerlerinin arttığı, ilerleme oranın artmasıyla delaminasyon değerlerinin düştüğü tespit edilmiştir. Elde edilen ilerleme kuvvetleri ilerleme oranın artmasıyla artmakta, kesme hızının arttırılmasıyla ise azalmaktadır. Titreşim ve moment değerleri açısından hibrit ve dolgusuz kompozitler arasında önemli bir fark olmadığı görülmüştür.
