Properties of the Treated Kenaf/Polypropylene (PP) Composites

Untreated and treated kenaf fibers were used in the fabrication of kenaf/polypropylene (PP) composites. The ratio of the fibers as fillers and PP as matrix was 40:60 in wt%. Small amounts of maleic anhydride grafted polypropylene (MAPP) were added as a coupling agent. Fourier transform infrared (FTIR) spectroscopy was used to estimate the cellulose contained in the treated kenaf fibers. A flexural test of the composites was conducted by...
