“…Activation energies of pectin reinforced the composites at a certain conversion ratio (range of 0.20 to 0.80) found. Thermal decomposition experiments have been carried out from 20 °C to 600 °C at a heating rate of 10 °C/min [34,35]. In this study, 5 wt.% and higher pectin powder reinforcement negatively affect the surface morphology of the polyester composite.…”

In this study, pectin powder is mixed homogeneously in unsaturated polyester (UP). For the production of polyester composite, methyl ethyl ketone peroxide (MEKP) and cobalt octoate (Co Oc) are added to the mixture. The obtained composite is poured into standard molds as a gel and allowed to cure for 24 hours. Some physical and chemical properties of the composite are determined and characterization processes are carried out. Density, Shore D hardness, thermal conductivity coefficient, and thermal stability of polyester composite are examined. According to the results obtained, pectin is used as a filler in the polyester composite. There is no change in the chemical structure of the polyester polymer with Fourier transform infrared (FTIR) spectroscopy. The density of polyester composites decreases as the reinforcement of 0 wt.%, 1 wt.%, 3 wt.%, 5 wt.%, and 7 wt.% pectin powder increases. Besides, the reinforcement of pectin powder as filler reduces Shore D hardness of the polyester composite. However, it has been observed that the thermal conductivity coefficient of the polyester composite increases as the filler ratio rises. In thermal decomposition experiments of the composite, the activation energy decreases slightly as the filler ratio increases. According to the optimization results, 3 wt.% pectin powder supplementation does not adversely affect both the surface morphology and thermophysical properties of the polyester composite.

“…Moreover, high biomass reinforcement weakens the thermal decomposition behavior of the polyester composite. The thermal stability of the composite is evaluated by calculating the activation energies found in the thermal degradation kinetics [29][30][31][32][33][34][35].…”

“…Especially plants with a fibrous structure are involved in the production of composites such as polyester and epoxy composite components. Biomass wastes such as sunflower stalk, apricot stone shell, corncob, Cornus alba, and Asphodelus aestivus have been reinforced into polymer composite [27][28][29][30][31][32]. The fibrous structure, elastic property, density, economy, workability, and compatibility of biomass wastes are very important.…”

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.

Organic wastes constitute an important part of environmental pollution. Disposal of these wastes can be achieved either by using recycling methods or as reinforcement material. In this study, research has been carried out on the use of organic wastes in composite materials. For example, the effects of organic fillers on the physical and chemical properties of polyester composites have been investigated. Organic wastes (biomass) are prepared as fillers after drying and grinding. Especially, biomass samples with a fibrous structure improve the mechanical properties of composites. The use of such organic wastes in polyester composites is preferred for obtaining both economical and low-density materials. However, such fillers should be used in optimum proportions in the composite. Because the use of these wastes at a high rate negatively affects both the surface morphology and the pore structure of polyester composites. Besides, the evaluation of these wastes in the production of polyester composites reduces the carbon footprint. Such fillers interact physically in the polyester composite. If no chemical modification is made, it does not react with polyester components and does not make a chemical bond. According to the evaluated results, it reduces the density and hardness of the polyester composite. Also, it decreases the thermal conductivity coefficient and thermal stability, albeit slightly.
