Investigation on The Effects of Nanoclay Particles on Mechanical Properties of Wood Polymer Composites Made of High Density Polyethylene-Wood Flour

In this study, the effect of nanoclay particles content on mechanical properties of wood polymer composite made of high density polyethylene and wood flour were investigated. For this aim, wood flour were compund with high density polyethylene at 50% by weight, and nanoclay with 0, 1, 3 and 5% were used, also 2% of MAHDPE was also used as the coupling agent in all formulatins. Then wood polymer nanocomposite were manufactured in injection molding. Mechanical tests such as tensile, bending and notched impact were performed on samples. Results indicated flextural modulus, flextural strength, tensile modulus tensile strength and were increased by increasing of nanoclay particles content, however, notched impact strength was reduced. Also, studies on structural behavior of wood polymer nanocomposite with x-ray showed that nanoclay distributed as intercalation structure in polymer matrix, and the d-spacing of layers were increased with increasing of nanoclay particles conten
