Abstract

Bu çalışmada hidrotermal yaşlanmaya maruz bırakılan hibrit aramid/cam/epoksi kompozit numunelerinin su emilim davranışları deneysel olarak araştırılmıştır. Vakum destekli reçine infüzyon yöntemi (VARIM) ile üretilen kompozit numuneler saf su ve deniz suyunda 25°C ve 70°C sıcaklıkta 1000 saat boyunca kontrol edilebilir bir yaşlandırma kabininde bekletilmiştir. Farklı uzunluk genişlik-1 (L w-1) oranlarında, 10 ve 15, hazırlanan hibrit kompozitlerin su emilim özellikleri su tipi, sıcaklık ve kompozit katman dizilimi gibi faktörlere göre değerlendirilmiştir. Hibrit kompozit numunelerin su emilim sonuçları, sıcaklığın su emiliminde etkili olduğunu, sıcaklık artışının daha fazla su emilimine neden olduğunu göstermiştir. Ayrıca, her iki sıcaklıkta saf su ile kıyaslandığında, deniz suyunda yaşlandırılan numuneler genellikle daha fazla su emmiştir. Su alım deneyleri, hibrit kompozit numunelerde katman dizilim şeklinin maksimum su alım oranında son derece etkili olduğunu göstermiştir. Numunelerin L w-1 oranının artması her iki sıcaklık ve su tipinde de daha fazla su emilimine sebep olduğu belirlenmiştir.

Investigation of the Water Absorption Behavior of Hydrothermally Aged Hybrid Aramid/Glass/Epoxy Composites

Abstract

In this study, water absorption behaviors of hybrid aramid/glass/epoxy composite samples exposed to hydrothermal aging were experimentally investigated. Composite samples produced by vacuum assisted resin infusion method (VARIM) were kept in distilled water and sea water at 25°C and 70°C for 1000 hours in a controllable aging cabin. The water absorption properties of hybrid composites prepared at different length width- 1 (L w-1) ratios, 10 and 15, were evaluated according to factors such as water type, temperature and composite layer sequence. The water absorption results of the hybrid composite samples showed that temperature is effective in water absorption and the increase in temperature causes more water absorption. Also, samples aged in seawater generally absorbed more water than distilled water at both temperatures. Water intake experiments have shown that the stacking sequence of composites is extremely effective at the maximum water intake ratio in hybrid composite samples. It has been determined that the increase in the L w-1 ratio of the samples causes more water absorption in both temperatures and water types.
