Fiber reinforced composites plays major role inimproving the strength of various applications in current trends.Based on these trends the combination of natural jute/coir fiberhybrid composite of different size of fiber length was examined inthis study. The hybrid fiber composite was fabricated bycompression moulding technique by impregnating jute fiber andcoir fiber with unsaturated polyester resin, Cobalt octoate andmethyl-ethyl-ketone peroxide as accelerator and catalyst. Then theprepared mould placed into the oven to dry for 4 hrs. at 50°Cbeneath closely to vacuum condition then convert the cured mouldto the hot press initially for 1 hr at 105°C under 84 bar pressureuntil while squeeze out the excess resin, then it was cooled in coldpress under constant pressure of 275 bar pressure for 15 min toprevent the warpage of hybrid composites. The micro hardness,tensile, flexural, impact strength of hybrid composite was carriedout and the morphology of the composites was evaluated andcompared. The test results of the hybrid composite were analyzedby one way ANOVA analysis technique and it shows significantdifference among the groups.
