Abstract

In this study, composite boards were produced using waste plastic furniture parts and wood flour. Wood flour was used at rates of 0%, 15%, 30% and 45% in the preparation of composite boards. Thus, 1 control and 3 composite groups were created. The boards are produced in dimensions of 3.5x175x175 mm (thickness, width, length). Density, flexural strength, flexural modulus, deformation at break, tensile strength, tensile modulus, elongation at break, hardness tests and thermal gravimetric analysis (TGA) and differential scanning calorimeter (DSC) analysis were performed on the produced composite boards. According to the obtained data, it was determined that as the percentage of wood flour in the composite groups increased compared to the control group, the values of flexural strength, deformation at break, tensile strength and elongation at break decreased whereas the values of density, hardness, flexural modulus and tensile modulus increased. According to the TGA and DSC analysis results, it was understood that the waste plastic furniture parts were composed of linear low density polyethylene (LLDPE) and polypropylene (PP) polymer materials, also the decomposition temperature of the composite materials partially increased with the increase in the percentage of wood flour.
