The effect of using Palm Flour in the Manufacture of pp-based wood-plastic Composite

In this research, the effect of the quantity of filler and coupling agent (MAPP) on the physical and mechanical properties of Polypropylene composite reinforced with flour from the annual pruning of palm leaves (Shahani species), were studied. For this purpose, the palm flour in three levels of 30%, 40%, 50% and two levels of Maleic anhydride grafted polypropylene 4% and 6% were used as variable factors. Then the Physical and mechanical properties of samples including, thickness swelling after 2 and 24 hours of immersion in water, bending strength, bending modulus, tensile strength, tensile modulus and impact strength were measured. The result of this research showed that by increasing palm flour, the bending strength, tensile strength and impact strength were decreased and on the other hand the thickness swelling, bending modulus, tensile modulus were increased. It was also found that by adding MAPP, thickness swelling, bending strength, bending modulus, tensile strength and tensile modulus were improved. This means that with increased consumption of palm flour, adding coupling agent leads to improve the quality of interface and significant changes; especially dimensional stability and MOE is achieved.
