“…The peaks at 1400 and 1450 cm-1 observed in the polyester composite spectrum indicate the aromatic ring. The peak at 1260 cm -1 seen in the polyester spectra is due to the twisting vibration of the CH2 groups [6][7][8][9][10].…”

In this research, both environmentally friendly and economical composites have been produced by using biomass wastes in unsaturated polyester. The use of renewable biomass wastes as a filler in unsaturated polyester is reduced the carbon footprint of the composite obtained. A low-density and flexible structure could be achieved according to the intended use of polyester composites. While the density of the pure polyester polymer not reinforced with biomass is around 1206 kg/m 3 , the density of the 5 wt.% filler added composite decreases to 1167 kg/m 3 . Biomass waste (Asphodelus aestivus L.) reduces Shore D hardness of the polyester composite and turns it into a more flexible and easy-to-process material. It has been observed that the thermal conductivity coefficient of the biomass reinforced polyester composite shows a slight increase compared to the pure polyester composite. Besides, it has been determined that as the amount of biomass in the polyester composite increases, the activation energy decreases. The specific bond structure in the polyester polymer has been determined by Fourier transform infrared (FTIR) spectroscopy. Biomass waste is not making a chemical bond with polyester, it is only used as a filler. Also, the surface morphology of the polyester composite has been investigated with the help of scanning electron microscopy (SEM). The use of 3 wt.% Asphodelus aestivus L. biomass as a filler does not create a negative pore structure on the composite surface.

In this study, waste corncobs are ground and used in the polyester composite. Homogeneous distribution is provided by mixing it into unsaturated polyester (UP) as a filler under laboratory conditions. Then, methyl ethyl ketone peroxide (MEKP) and cobalt octoate (Co Oc) catalysts are added to the mixture. After mixing the additives and fillers used in certain amounts for a short time, the polyester composites are poured into standard molds and waited for curing. The density, Shore D hardness, and thermal decomposition behavior of the composite obtained after curing have been investigated. As the amount of corncob in the mixture increases, the density of the polyester composite decreases. Besides, the rise in the ratio of this filler in the mixture also increases the porosity of the polyester composite. In the thermal conductivity measurements, it is seen that the thermal conductivity coefficient of the polyester composite increases, albeit slightly, according to the increasing amount of filler. Also, corncob reinforcement reduces both Shore D hardness and activation energy of the polyester composite. According to the results obtained, it was observed that the use of corncob reinforcement above 3 wt.% negatively affected the surface morphology and mechanical properties of the composite. While obtaining an economical and light polyester composite, attention should be paid to the amount of filler so that both thermal and mechanical properties are not weakened.
