Abstract :The research article focused on the effect of corn shell reinforced with epoxy composites. The randomly oriented corn shell reinforced/epoxy composites were prepared by hand lay-up technique with 5%, 10%, 15%, 20%, and 25% pomice powder weight. Tensile, flexural, and water absorption tests were used to determine the composite’s mechanical properties, The obtained results revealed that 20 wt% and 15 wt% pumice powdercould produce corn shell -reinforced composite with the highest tensile strength, flexural strength, and interfacial adhesion among all the prepared composites. The added of the pumice powder into the corn shell /epoxy composites enhanced their mechanical, and water absorption. The tensile and flexural strengths of the corn shell/pumice powde –epoxy composites (20wt% and 15wt%) were 11.745 and 11.250 MPa, respectively. In additon, The 25 wt.%, composite also displayed less water absorption behavior compared to the other composite.
