This research studied the effect of filler dimensions on some major properties of pineapple leaf fibre-reinforced polypropylene composites. In this study, composites of PALF/PP were produced, the PALF were extracted from pineapple leaves. This was achieved by adopting the mechanical scrapping method. The surface of the extracted PALF were modified with 6%NaOH, 14% C3H6O3, 6% HNO3 and 3% ZnCl. The surface modified PALF as well as the control (untreated/unmodified) gave FTIR...
