The aim of this research work is to study the influence of chemical treatments on flexural strength and impact strength of areca fiber reinforced natural rubber composites. Hence in this study, untreated, alkali treated, permanganate treated, benzoylated and acrylated areca fiber reinforced natural rubber composites were fabricated by using heat press machine under 40%, 50%, 60% and 70% fiber loadings at a compounding temperature of 130 oC. The evaluation of flexural strength and impact strength of untreated and all chemically treated areca-natural rubber composites was done by following ASTM standard procedures. With increase in fiber loading from 40% to 60%, the flexural strength and impact strength of untreated and all chemically treated areca-natural rubber composites were increased and beyond, they showed a decline. Amongst untreated and all chemically treated areca-natural rubber composites, the highest flexural strength and impact strength was shown by acrylated areca-natural rubber composites with 60% fiber loading.
