Empty fruit bunch fibre – polypropylene composites with treated and untreated maleated polypropylene (MAPP) were produced. The MAPP used as coupling agents were Epolene-43 (commercial MAPP) and MAPP samples produced in laboratory. Analyses on the MAPP samples included FTIR, acid number and grafting degree (Gd) to determine the number of anhydride groups available in the MAPP. The MAPP-treated composites had better tensile results than the untreated ones. The dimensional stability of the MAPP- treated samples improved with water absorption and as the thickness swelling decreased. The scanning electron microscopy (SEM) of the interfacial regions between filler and matrix showed the treated composites to have better interaction than the untreated samples.
