| The present article summarizes an experimental study on the mechanical behavior of high density polyethlene (HDPE)/ wheat straw (WS) composites. The mean goals of this investigation were using of wheat straw (WS) as a filler (reinforcer), effectiveness of straw flour fiber with different size (10-30 mesh as fine) and (30-50 mesh as coarse) on mechanical properties of composites and effect of maleic anhydride (MA) as a coupling agent treatment is performed to improve interfacial adhesion between the fibers and HDPE matrix. Generally, (16) treatment were conducted as (8) treatment of HDPE with 10, 20, 30, 40% coarse wheat straw with (0.5, 1.0, 1.5, 2.0) MA, 8 treatment of (HDPE) with 10, 20, 30, 40% fine wheat straw (WS) with (0.5, 1.0, 1.5, 2.0) MA, (HDPE) (WS). This study focused upon tensile strength, flexural, impact strength and hardness of reinforced polyethylene. The results showed that increase wheat straw rate to 30% in both fine and coarse, improved [tensile, strength hardness flexural and impact strength] values, Fine (WS) particles sample showed better, then coarse (WS) when addition for HDPE as fiber to produced composite material.The optimum formulation for the (HDPE and WS) composites on the mechanical properting is (30wt.%WS as fine-HDPE-1.5wt.%MA). | ||
