Composites of rice husk powder (RHP)-filled recycled polypropylene (rPP) as a function of crude palm oil (CPO) and trimethylolpropane triacrylate (TMPTA) were prepared. Composites containing various amounts of RHP, acrylic acid (AA), CPO and TMPTA were prepared, and the effects on the properties of the resulting composites were investigated. As a function of RHP loading, the tensile strength was enhanced to an optimum value at an rPP to RHP ratio of 7:3. The addition of CPO increased the tensile strength (TS), elongation at break (Eb) and melt flow index (MFI) of the composites. The biodegradation of rPP/AA/RHP bio-composites was also increased with the addition of both CPO and TMPTA.
