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.enhigh density polyethyleneliquid epoxidized natural rubberrice husksUR-Proceedings
