Physical and Chemical Properties of Organic Waste Reinforced Polyester Composites

Abstract

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.
