A Comprehensive Review on Parametric Investigations of Al-MMC Reinforced with Waste Reinforcements

Composite materials, engineered for both lightweight and high strength, find extensive applications in aerospace, automotive, and structural realms. Comprised primarily of a matrix and reinforcement, they offer versatility and performance. This article focuses on aluminum metal matrix composites employing waste reinforcements, such as marble powder, rock powder, and ceramic-based materials like quarry powder, fly ash, and red mud. The study examines parametric investigations into these composites to enhance their mechanical and tribological properties through various reinforcements. A comparative analysis of the maximum tensile and compressive strengths achieved with different reinforcements is provided, along with a summary of parametric variations such as particle size, distribution, concentration, and the characterization techniques employed. The review underscores the widespread adoption of the stir casting method in fabricating aluminum metal matrix composites, attributed to its cost-effectiveness, versatility, and ease of implementation.
