Abstract

Current research was conducted to investigate the effect of Hydrothermal modification on the properties of composite made from bark flour-polypropylene. Wood plastic composites were divided in two groups of control and Hydrothermal modification, in 4 subgroups; 10, 20, 30 and 40% of bark filler ratios. Test samples were prepared with maleic anhydride-grafted polypropylene as coupling agent by injection molding method. According to the results, bark flour increased water absorption, tensile and bending modulus. High ratio of bark fillers declined mechanical strength. Hydrothermal modification significantly improved physical and mechanical properties of composite. Tensile and flexural modulus of composite material had the highest improvement with lignocellulosic material of hornbeam bark flour. By adding bark flour, impact resistance had the greatest decrease between mechanical properties. Hydrothermal modification by increasing the crystallinity, hemicellulose degradation, loss of polarity, increased compatibility between the two phases of wood plastic composite and uniform distribution of fillers in polymeric matrix, increased mechanical resistance.
