Synthesis of Egyptian Rice Straw Composites

Rice straw strands were used as strengthening fillers as a part of various polymers, six composites were set up by utilizing polypropylene (PP) and polyethylene (PE) as matrix with three proportion containing 40%, 50 %and 60% by weight rice straw. Composites were effectively prepared by extrusion. The samples were characterized by tensile tests, impact test, wear, hardness and scanning electron microscopy (SEM). The consequences of the mechanical properties demonstrates that rice straw can be utilized as an option support for polypropylene and polyethylene .It was shown that, hardness, impact strength and modulus of versatility increment with expanding the polymer proportion. Composites PP 40% weight rice straw has higher mechanical properties than the PE in the same sythesis. Scanning electron microscopy (SEM) was utilized to look at the structure of the break surface and to legitimize the variety of the deliberate mechanical properties
