Abstract
The objective of this study was to investigate the influence of coupling agent and the content of lignocellulosic material on tensile strength and physical properties of wood/plastic composite produced from recycled polypropylene using mat forming procedure. Recycled polypropylene and three levels of Eucalyptus camaldulensis sp. wood powder (60, 65 and 70%) and 5% of MAPP were used. The results of tensile strength and physical properties were statistically analyzed using factorial experimental design. The results indicated that the tensile strength and modulus of composites containing MAPP were statistically higher than those without MAPP. These properties were increased as the content of wood powder is reduced. The interaction effect of wood powder and MAPP on tensile strength was statistically significant and composites produced using 60% wood powder and 5% MAPP were the highest. The results of composite water absorption after 2 and 24 hours soaking in water revealed that these characteristics were lower when MAPP is used or the content of wood powder is reduced. Thickness swelling and water absorption after 2 hours in boiling water showed that properties are lower when 60% wood powder or MAPP is used.
