Natural fibres are widely used as plastic composite material reinforcement. Sisal fibre is a promising reinforcement for use in composites on account of its low cost, low density, high specific strength and modulus, no health risk, easy availability in some countries and renewability. In the present work short sisal fiber used as reinforcement and epoxy resin as matrix. The composite was prepared with randomly oriented fiber with different proportions of fiber and matrix ratio by means of open molding process. The effect of fiber loading on mechanical properties such as impact strength, tensile strength and hardness properties are investigated. The composite with a 30% wt. sisal fibre for 5mmm specimen thickness gives high impact toughness at a notch depth of 6mm and is desired to prevent the failure of sisal-epoxy composite during an impact loading. The impact toughness increases with increasing the fibre volume fraction and also increases with decreasing the specimen thickness. The material has high impact toughness that improves the ductility and impact energy.
