Özet

Bu çalışmada doğal kenevir elyaf kumaş ile üretilen nano silika katkılı polimer kompozitlerin su ile yaşlandırılmasının Charpy darbe davranışına etkileri araştırılmıştır. Nano parçacık katkısının hidrofilik davranışa etkilerini gözlemlemek amacıyla nano silika parçacıkları ağırlıkça %0.5, %1.5 ve %3 oranlarında reçineye eklenerek kompozit üretimleri gerçekleştirilmiştir. Üretilen kompozitlerden ISO 179/92 standardına göre 55 x 10 mm ölçüsünde numuneler kesilmiş ve 800 saat 30℃’de çeşme suyunda yaşlandırma işlemi gerçekleştirilmiştir. Yaşlandırılan numuneler 15 J sarkaç enerjili Köger 3/70 darbe test cihazı ile test edilmiştir. Ölçülen sonuçlar hem emilen enerji hem de tokluğu gösterecek şekilde tablo haline getirilmiştir. Testler sonucunda nano katkısının tokluğu ve emilen enerjiyi düşürdüğü görülmüştür. %1.5 nano silikanın tokluğu %33.73 emilen enerjiyi ise %22,54 azalttığı gözlenmiştir. Yaşlandırma sonrasında ise darbe enerjisinde en fazla düşüş %1.5 nano oranında %33.4 olarak ölçülürken toklukta %3 nano oranında %32 olarak ölçülmüştür.

Abstract

In this study, the effects of water aging on the Charpy impact behavior of polymer composites reinforced with natural hemp fiber fabric and nano-silica were investigated. To observe the influence of nano-particle addition on hydrophilic behavior, nano-silica particles were added to the resin in weight percentages of 0.5%, 1.5%, and 3% for composite production. Samples with dimensions of 55 x 10 mm were cut from the produced composites according to ISO 179/92 standard, and the aging process was carried out in tap water at 30℃ for 800 hours. The aged samples were tested using a Köger 3/70 impact test device with 15 J pendulum energy. The measured results were tabulated to show both absorbed energy and toughness. The test results revealed that the addition of nano-silica reduced both toughness and absorbed energy. It was observed that 1.5% nano-silica reduced toughness by 33.73% and absorbed energy by 22.54%. After aging, the greatest decrease in impact energy was measured as 33.4% for the 1.5% nano-silica, while the greatest reduction in toughness was 32% for the 3% nano-silica.
