Abstract: In a fast-growing world, composites have been the most popular material in recent years. Among composites, aluminium matrix composites (AMCs) are significant among researchers because of their effective and remarkable properties. Eggshell (ES) is regarded an aviculture waste, and its disposal poses a significant environmental risk. The righteous usage of ES as a bio-waste should be strongly encouraged in our society to alleviate environmental concerns. Thus, the current study aims to develop and examine the mechanical properties of AA2024/SiC/carbonised eggshell hybrid green aluminium-based metal matrix composites (AMMCs). The reinforcement composition in this study ranges from 3-12 wt. % of SiC and ES particles. Tensile strength and hardness were investigated in the developed composite. The results revealed that hardness and tensile strength of AA2024 hybrid green composite were increased significantly as compared to base aluminium alloy. Also, fracture mechanism was been analysed along with it that showed ductile nature of developed composites.

Keywords: eggshells; tensile strength; hardness; fractography; hybrid green composite; aluminium-based metal matrix composites; AMMCs; stir casting.
