Recently there has been a great interest in the industrial applications of composites developed from natural fibers, bio or industrial waste. Present work is an attempt to synthesize composites using a bio waste material i.e. peel arko. Composites with 3, 5,7 and 9 wt % arko shell (AS) particulate reinforced polyester composites have been synthesized using Hand layup technique. Mechanical properties have been investigated in detail. Considerable increase in tensile strength and young’s modulus and hardness test was noticed with increase in filler content. Composites were found to be more resistant to impact strength. was found to be quite high in comparison to polyester.
