Study on manufacturing wood-plastic composite based on Acacia mangium flour and recycled polypropylene (PP)
determine the influence of the weight percentage of Acacia'mangium flour and recycled polypropylene at different percent levels: 50/50, 60/40, 70/30 to the mechahical properties of wood plastic composite: melt flow index of wood plastic composite is from 1.38 to 1.15 g/10 minutes
density from 1.04 to 1.15 g/cm3, water absorption from 6.58 to 7.52 percent, the swelling of thickness from 3.21 to 5.12 percent, modulus of elastic from 18.27 to 17.23 MPa, tensile strength from 16.32 to 13.38 MPa. When the rate of wood flour/plastic is changed, the physical properties of the product changes: if increase the rate of wood flour, the melt flow index of wood plastic composite decreased, the swelling of thickness increased
modulus of elastic, tensile strength decreased.
