Özet:

 In this study, Ficus elastica leaves have been reinforced into an epoxy composite and some physical and chemical characterization of the obtained composite is made. Ficus elastica leaves are ground between 297 and 149 microns. The biomass Ficus elastica prepared as a filler material is kept in sodium hydroxide  7 NaOH solution for 24 hours for alkali activation. It is then washed three times with distilled water and dried in an oven at 75 C for 3 hours. Composite production is carried out by reinforcing the prepared filler to the epoxy resin in certain proportions by mass. The effect of the biomass filler added at the rate of 0 wt., 1 wt., 3 wt., 5 wt., and 7 wt. on the density, Shore D hardness, thermal conductivity coefficient, and activation energy of the epoxy composite is determined. According to the results obtained, the density of the epoxy composite decreases as the filler ratio in the mixture increases. Shore D hardness of epoxy composite decreases with the addition of biomass filler. The epoxy composite produced with biomass reinforcement reduces both the thermal conductivity coefficient and the activation energy. Besides, when the chemical bond structure of the obtained polyester composite is analyzed by Fourier transform infrared spectrometer FTIR, it is seen that there is a physical interaction. According to scanning electron microscopy SEM images, 5 wt. and 7 wt. reinforcement of Ficus elastica leaves negatively affects the surface morphology of the epoxy composite.

 Bu çalışmada, Ficus elastika yaprakları takviye edilerek epoksi kompozit üretilmekte ve elde edilen kompozitin bazı fiziksel ve kimyasal özellikleri karakterize edilmektedir. Ficus elastika yaprakları 297 ile 149 mikron arasında öğütülmektedir. Dolgu maddesi olarak hazırlanan biyokütle Ficus elastika alkali aktivasyonu için  7lik sodyum hidroksit NaOH çözeltisinde 24 saat bekletilmektedir. Daha sonra distile su ile 3 kez yıkanmakta ve 75 C sıcaklıkta etüvde 3 saat kurutulmaktadır. Kompozit üretimi, hazırlanan dolgu maddesinin epoksi reçineye kütlece belirli oranlarda takviye edilmesiyle gerçekleştirilmektedir. Ağırlıkça  0,  1,  3,  5 ve  7 oranlarında eklenen biyokütle dolgu maddesinin yoğunluk, Shore D sertlik, ısıl iletkenlik katsayısı ve aktivasyon enerjisi üzerine etkisi epoksi kompozitte belirlenmektedir. Elde edilen sonuçlara göre karışımdaki dolgu oranı arttıkça epoksi kompozitin yoğunluğu azalmaktadır. Epoksi kompozitin Shore D sertliği, biyokütle dolgu maddesi ilavesiyle azalmaktadır. Biyokütle takviyesi ile üretilen epoksi kompozitin hem ısıl iletkenlik katsayısını hem de aktivasyon enerjisini düşürmektedir. Ayrıca elde edilen polyester kompozitin kimyasal bağ yapısı Fourier dönüşümlü kızılötesi spektrometre FTIR ile incelendiğinde fiziksel bir etkileşimin gerçekleştiği görülmektedir. Taramalı elektron mikroskobu SEM görüntülerine göre, Ficus elastika yapraklarının ağırlıkça  5 ve  7 takviyesi, epoksi kompozitin yüzey morfolojisini olumsuz etkilemektedir.
