Some mechanical properties of WPCs with wood flour and walnut shell flour

This study used a high-density polyethylene (HDPE) polymer matrix, pine-wood flour (PWF) and walnut-shell (WSF) to produce wood-plastic composite (WPC) boards. The PWF WSF filler amounts were adjusted 20%, 30%, 40% by weight. Some of the mechanical properties produced boards comparatively investigated, such as flexural strength, modulus, deformation at break, tensile elongation break. Flexural tests performed according ASTM D790 D638, respectively. According data obtained, break decreased content increased. In addition, modulus values all test groups increased with content. However, that smaller than those without filler.
