In the present communication, the effect of mercerization or alkali (NaOH) treatment on mechanical and wear behavior of chopped Roselle fiber-reinforced vinyl ester (CRFRV) composite have been studied as the function of fiber content. The results show that the tensile, flexural and impact strength values of untreated and treated fiber composites increased with increasing fiber content up to 40 wt% and then dropped. It was observed that the better fiber content (weight percentage) for better mechanical properties is 40 wt% at both the untreated and treated fiber composites. The wear resistance of the composites fabricated with treated Roselle fibers was found to be of better wear resistance composites fabricated by untreated fibers.
