Al2O3 ve TiO2 nanopartikül katkısının cam elyaf takviyeli kompozitlerin mekanik özelliklerine ve burkulma davranışına etkisi

Bu çalışmada Al2O3 ve TiO2 nanopartikül takviyesinin e-cam elyaf takviyeli polimer kompozitlerin mekanik özelliklerine ve burkulma davranışına etkisi deneysel olarak incelenmiştir. Bu kapsamda saf, %2 Al2O3 katkılı ve %2 TiO2 katkılı e-cam elyaf takviyeli üç farklı kompozit plaka vakum destekli reçine infüzyon yöntemi ile üretilmiştir. E-cam elyaf olarak dokuma (woven) kumaş kullanılmış olup, üretilen plakalar CNC freze tezgâhında çekme, basma, eğilme, darbe ve burkulma deneylerini gerçekleştirmek için standartlara göre kesilmiştir. Elde edilen bulgular neticesinde %2 Al2O3 ve %2 TiO2 nanopartikül katkılı kompozitlerin, saf haldeki kompozite göre mekanik özellikleri ve burkulmadaki kritik yükü iyileştirdiği tespit edilmiş ve %2 Al2O3 katkılı kompozitin %2 TiO2 katkılı kompozite göre daha fazla iyileşme sağladığı görülmüştür.
