Use of Inorganic Wastes as Fillers in Production of Polyester Composites and Evaluation of Properties of Obtained Composite

Abstract

The use of industrial factory wastes as a filler in polymer composite materials is becoming more and more common. In this way, these wastes that cause environmental pollution are eliminated and new composite materials are developed. Polymer composites with low cost and high thermal stability are preferred in many sectors. In this research, some physical and chemical properties of inorganic waste reinforced polyester composites have been evaluated. The use of industrial inorganic wastes as fillers in polyester composites develops some thermophysical properties of composites. In particular, such industrial wastes are dried before being used in the composite, the particle size is reduced, and it is ensured to have a homogeneous structure. This type of waste, which is used as filler, is used in the polyester composite in optimum proportions. The use of high inorganic fillers in polyester both weakens the mechanical strength of the composites and negatively affects the matrix structure. Besides, inorganic waste reinforcement raises the surface hardness of polyester composites. Such fillers are improved both the thermal stability and non-flammability of the polyester composite. High-density inorganic fillers are used to obtain a high-density and economical polyester composite. Low-density inorganic industrial wastes also reduce the density of composites. However, the reinforcement of inorganic fillers into polyester at a high rate adversely affects both the surface morphology and the workability of the produced composites.
