Utilizing seashell waste which is combined mainly by CaCO3 has the potential to be a bio-filler for polymers.In the present study, seashells were ball-milled using two different ball-milling methods resulted in different particlesize distributions. Tensile and flexural properties of the seashell-filled epoxy resin were studied and resulted in a higheryield strength, flexural strength, flexural modulus and Young’s modulus. Employing waste seashell as bio-filler forepoxy polymers can be considered as a prospective and valuable method for reducing cost of industrial productions andsimultaneously improving mechanical properties of bio-composites.
