Abstract

Sandwich structures which are categorized under the hybrid materials, provide to obtain very light-weigth and very high resistance to bending when compared to commonly used laminated composite materials. These structures are now called as advanced composite materials and newly used in automotive, aviation, marine and defense industries. In this study, sandwich plates having different core thicknesses and were fabricated with carbonfiber skins and epoxy matrix and the effect of core thickness on bending resistance was investigated. The test specimens were cut according to standard dimensions provided in ASTM C393/M 393C standard then subjected to three point bending test. The results of the tests showed that there is a good improvement on bending resistance of the materials although the weight of the specimens was not increased much. Also, the failure modes occured on the materials was examined

Özet

Hibrit malzeme sınıflandırma kategorilerinden biri olan sandviç yapılar, oldukça hafif ve eğilme rijitliği çok yüksek teknolojik malzemelerin elde edilmesine olanak sağlamaktadır. Literatürde ileri seviye kompozit malzemeler olarak adlandırılan bu yapılar, otomotiv, havacılık, gemi ve savunma endüstrileri gibi alanların yenilikçi malzemeleridir. Bu çalışmada farklı çekirdek kalınlığına sahip PVC köpük malzemesi ve örgü dizilimli karbon elyaf kumaşları kullanılarak bir epoksi matris ile sandviç plakalar üretilmiş ve çekirdek kalınlığının eğilme direncine olan etkisi araştırılmıştır. ASTM C393/M 393C standardında belirtilen boyutlarda elde edilen numuneler üç nokta eğilme testine tabi tutulmuştur. Testler sonucunda numune ağırlığında fazla artış olmamasına rağmen malzemenin yük taşıma kapasitesinde iyileşme olduğu gözlemlenmiştir. Ayrıca, malzemede meydana gelen hasar durumu da incelenmiştir
