Bu çalışmada, ağırlıkça % 0.5 Hekzagonal Bor Nitrür Nanoplateler (hBNNPs) ile ağırlıkça farklı oranlarda (% 0.5, 1 ve 1.5) nano gümüş (Ag) parçacıklı epoksi bazlı nanokompozitlerin üretimi, mekanik ve termal özellikleri araştırılmıştır. ASTM D638-10 standardına göre üretimi yapılan epoksi esaslı hibrid nanokompozitlerin çekme numuneleri sabit yük altında çekme testine tabi tutulmuştur. Modifiye edilmiş epoksi hibrid nanokompozitlerin maksimum yükleri, çekme dayanımları, elastiklik modülleri, toklukları ve uzama değerleri hesaplanmış olup, bu testin sonucunda bu özellikler referans numuneyle kıyaslanmıştır. Referans numune ile ağırlıkça % 0.5 oranındaki BNNPs ve ağırlıkça % 1 oranındaki nano Ag parçacık takviyeli nanokompozitin maksimum yükleri sırasıyla 1742.11 N ve 2262.80 N olup, 0.5BNNP+1NanoAg epoksi esaslı kompozit % 30 oranında artış gözlemlenmiştir. Hibrid nanokompozitlerin kırılmış yüzeyleri taramalı elektron mikroskopu (SEM) ile incelenerek hasar mekanizmaları ortaya çıkarılmıştır. Ayrıca epoksi reçine ile BNNPs ve nano Ag takviyeli epoksi nanokompozitlerin camsı geçiş sıcaklığı, ergime sıcaklığı, termal bozunma sıcaklığı ve kütle kaybı, Termogravimetri ve Diferansiyel Termal Analizleriyle (TGA/DTA) incelenmiştir.
In this study, the production, mechanical and thermal properties of nanocomposites based on epoxy particles (Ag) in weight different ratio (% 0.5, 1 and 1.5) with 0.5 percent hexagonal bor nitrogen nanoplates (hBNNPs) and 0.5 percent hexagonal bor nitrogen nanoplates (hBNNPs) were studied. According to ASTM D638-10, epoxy-based hybrid nanocomposite drawing samples were tested under a fixed load. The maximum loads, drawing resistance, elasticity modules, thickness and extension values of modified epoxy hybrid nanocomposites were calculated, and the results of this test compared these characteristics with the reference sample. With the reference sample, the maximum loads of BNNPs with a weight of 0.5 % and nano Ag particles with a weight of 1 % are 1742.11 N and 2262.80 N, respectively. 5BNNP+1NanoAg epoxy-based composite has been observed an increase of 30%. The damage mechanisms have been detected by examining the broken surfaces of hybrid nanocomposites with an electron microscope (SEM) scan. It has also been studied by the epoxy rechin and the BNNPs and nano Ag supplemented epoxy nanocomposites by the cams transition temperature, ergime temperature, thermal decomposition temperature and mass loss, thermogravimetry and Differential Thermal Analysis (TGA/DTA).
In this study, the production, mechanical and thermal properties of hexagonal boron nitride nanoparticles (hBNNPs) and different ratios (0.5, 1, and 1.5% by weight) of nano silver (Ag) particles epoxy based nanocomposites were investigated. Tensile specimens of epoxy based hybrid nanocomposites produced according to ASTM D638-10 were subjected to tensile test under constant crosshead speed. The maximum loads, tensile strengths, modulus of elasticity, toughness and elongation values of the modified epoxy hybrid nanocomposites were calculated and these properties were compared with the reference sample. The reference sample and 0.5% by weight of BNNPs and 1% by weight of nano Ag particles reinforced nanocomposite the maximum loads were 1742.11 N and 2262.80 N respectively, 0.5BNNP+1NanoAg epoxy based nanocomposite was observed increase of 30%. The fracture surfaces of hybrid nanocomposites were examined by scanning electron microscopy (SEM) and the damage mechanisms were revealed. In addition, epoxy resin and BNNPs and nano Ag reinforced epoxy nanocomposites glass transition temperature, melting temperature, thermal decomposition temperature and mass loss, Thermogravimetric and Differential Thermal Analysis (TGA / DTA) were examined.
