MAgPP an Effective Coupling Agent in Rice Husk Flour Filled Polypropylene Composites


Article Preview

Different properties (tensile strength, elongation, modulus, impact strength) of rice husk (RH) reinforced polypropylene (PP) coupled by Maleic-Anhydride grafted Polypropylene (MAgPP) have been investigated. MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way. Micrographs shows weak coupling in between RH and PP without MAgPP.
