Abstract
Öz: Cam elyaf takviyeli polimer matrisli kompozit malzemeler endüstride, otomotiv sanayinde, inşaat ve diğerbirçok alanda kullanılmakta olan mühendislik malzemeleridir. Bu malzemeler matris yapısını oluşturan birpolimer reçinesi içerisine cam elyafların eklenmesi sonucunda elde edilmektedir. Bu çalışmada vakum desteklireçine transfer metodu ile üretilen ve değişik elyaf oranlarına sahip (hacimce %30, %40, %50 ve %60) kompozitmalzemeler hazırlanmış ve bu malzemelerin mekanik özellikleri incelenmiştir. Bu kompozitlerin üretimindematris malzemesi olarak Epikote 828 epoksi reçinesi kullanılmıştır. Elde edilen plaka halindeki kompozitmalzemelerden ASTM standartlarına uygun olarak numuneler kesilerek çekme, darbe ve üç nokta eğmedeneyleri gerçekleştirilmiştir. Tüm bu çalışmaların sonucunda cam elyaf oranının artmasıyla birlikte kompozitmalzemenin maksimum gerilme, çekme uzama, elastik modülü ve darbe dayanımı özelliklerinin yükseldiğigözlemlenmiştir.
Abstract: Glass fiber reinforced polymer matrix composite materials are engineering materials used in the_x000D_ automotive industry, construction and many other areas. These materials are obtained as a result of the addition_x000D_ of glass fibers into a polymer resin which constitutes the matrix structure. In this study, composite materials with_x000D_ various fiber ratios (30%, 40%, 50% and 60% by volume) were prepared with vacuum assisted resin transfer_x000D_ molding method and the mechanical properties of these materials were investigated. Epikote 828 epoxy resin is_x000D_ used as matrix material in the production of these composites. The tensile, impact and three-point bending tests_x000D_ were carried out by cutting samples according to ASTM standards from the composite materials obtained. As a_x000D_ result of all these studies, it was observed that the maximum tensile strength, tensile elongation, elastic modulus_x000D_ and impact strength of the composite material increased with the increase of glass fiber ratio.
