Variation of Mechanical Properties of Polypropylene Composites with the Additives Content: An Empirical Mathematical Modeling Study

Abstract

Polypropylene (PP) composites were prepared by using additives CaCO3/rice husk ash (RHA) as filler, low density polyethylene (LDPE) as modifier, and jute fiber as reinforcement. The effects of filler, modifier, and chemically treated and untreated jute fiber reinforcement on the mechanical properties of the PP composites were studied. The result shows that incorporation of RHA in the PP matrix improves the tensile properties up to 16% which is almost similar to that of CaCO3 incorporated PP composite. This result clearly indicates the potential use of RHA as filler in % LDPE, and 30 wt% jute fiber.
