Abstract
The mechanical properties of egg-shell (ES)/ Aluminium (Al) composites have been studied. In the present work, the egg-shell reinforced composites were prepared via stir casting at a temperature of 700 oC. The higher relative density varied in the range between ~87% to ~95% through stir casting technique and the densification of Alumnium composites reduced with the egg-shell powder addition. The hardness of composites (BHN: 99.8) increased by adding the ES powder upto 3 wt.%. The tensile strength of the composites increased upto 3 wt.% and further decreased with the addition of reinforcement. The impact strength of the ES/Al composites enhanced to 30 KJ/m2.
