Wood powder was surface treaded with rare-earth coupling agent(WOT) and the modified wood powder was analyzed by infrared spectrum.The wood-polymer composite(WPC) was manufactured by twin-screw extruder with materials of modified wood powder,recycled polypropylene(PP) and other additives.Influences of the contents of wood powder and WOT on mechanical properties and heat distorting temperature of WPC were studied.The fracture surfaces of WPC were analyzed with SEM photograph.The results showed that WOT could...
