Secondary Fiber / Recycled Polypropylene Composites

Secondary fiber reinforced recycled polypropylene composites have been developed. Post consumer used polypropylene, obtained from market, was processed to obtain recycled polypropylene. Secondary fiber has been obtained from post consumer used paper. Secondary fiber reinforced recycled polypropylene composites have been successfully processed by extrusion by using 2% maleic anhydride modified polypropylene that acts as an efficient compatibilizer and promotes interfacial adhesion between secondary fiber and recycled polypropylene. Samples and specimen have been processed by injection molding as per ASTM standards. Secondary fiber reinforced recycled polypropylene composites demonstrate higher tensile modulus as compared to matrix recycled polypropylene, and the tensile modulus of composites increases with increasing amounts of reinforcing fiber in composites. The tensile strength of the secondary fiber reinforced recycled polypropylene composites is higher as compared to matrix recy...
