    MODIFICATION EFFECT OF RICE HUSKSURFACE BY LENR ON MECHANICAL PROPERTIES OF COMPOSITE NR/HDPE REINFORCED RICE HUSK
    (2014-05-21) Syafri, Rahmadini; Ahmad, Ishak; Abdullah, Ibrahim
    In this study, Composites derived from 60% natural rubber (NR), 40% high density polyethylene (HDPE) and reinforced with variable compositions of rice husk (RH) powder were prepared using an internal mixer. The degree of mechanical reinforcement of the thermoplastic natural rubber (TPNR) matrix by rice husk (RH) powder was studied as a function of fiber surface modification via alkali treatment and liquid epoxidized natural rubber (LENR) coating. The tensile strength of the composite evaluated showed that pre-treatment of rice husk with 5% NaOH followed by coating with 10% LENR solution produced the maximum interaction and strong adhesion between fiber and matrix.
