Study on Properties of Wood-Composite Prepared from Wood Flour and Recycled Polycarbonate (Used CD)

This study was aimed to investigate the properties of wood-plastic composites made from recycled polycarbonate polymer (Used CD) and wood flour at levels of 0, 10, 20 and 30%. 3-7 mm thickness Boards were manufactured with a density of 1 g/cm3. Hot press time and temperature were adjusted as 12 min and 190 ° C with a pressure of 130 bar. Fixed amount of 2 % N-(2-amino-ethyl) -3- amino propyl tri-methoxy silane was used as a coupling agent. Physical and mechanical properties, including strength and flexural modulus, tensile strength, impact strength, water absorption and thickness swelling of the boards were studied. The results showed that, compared with control samples (neat recycled polycarbonate polymer), the mechanical properties of prepared composites were increased by increasing the wood flour ratio from 10 to 30%. Also, the amount of 72 hours water uptake of the composites was measured as 0%. The thermal stability of the neat polymer was found to be better that the manufactured composites. The overall thermal degradation of the composites was increased by increasing the wood portion.
