In the present work walnut particle reinforced composite material was developed. Ten wt%, 15 wt%, 20 wt% and 25 wt% (weight percentage) of walnut particles were mixed with epoxy resin (CY-230). Scanning electron microscopy (SEM) shows that the walnut particles were well dispersed in the epoxy resin matrix. Addition of walnut particles increased the modulus of elasticity of the bio composite. Addition of walnut particles in bio composite decreased the ultimate strength both in compression and tension. However, addition of walnut particles in bio composite increased the hardness. Flexural modulus of elasticity also increased with increasing walnut particles weight percentage, whereas flexural strength and strain decreased with increased weight percentage of walnut particles.
