Natural fibre have good mechanical properties like flexural, tensile, corrosion resistance, moisture absorption. They are ecofriendly, light weight and cost effective. Our study on Combination of Natural fibre with Synthetic fiber composite proves to provide good strength to cost ratio compared to existing Synthetic fibre composites. Initially for weight considerations of the composite coir fibre are alkali treated with NaOH solution at a particular concentration for 24 hours and is left to shadow dry for several days. This alkali treatment enhances the coir fibre making them smoother with considerable increase in their tensile properties. The alkali treated enhanced coir-glass composite provides higher tensile strength with reduced weight compared to non alkali treated composite of the same.
