Abstract

Al6061-based metal matrix composites (MMCs) reinforced with silicon carbide (SiC), graphite (Gr), and aluminum oxide (Al₂O₃) exhibit a unique combination of mechanical, thermal, and tribological properties, making them highly suitable for advanced engineering applications. SiC enhances hardness, wear resistance, and load-bearing capacity, while Al₂O₃ improves thermal stability and mechanical strength. Graphite provides self-lubricating properties, reduces friction, and lowers the composite’s density, improving fatigue resistance. The synergy of combining these reinforcements in an Al6061 matrix creates hybrid composites with significantly superior performance compared to single-reinforcement systems.  This review compares research findings on single-reinforcement composites (Al6061 + SiC, Al6061 + Al₂O₃, and Al6061 + Gr), highlighting the individual advantages and limitations of each reinforcement. Furthermore, hybrid combinations of these reinforcements demonstrate synergistic effects that enhance mechanical, thermal, and tribological properties, emphasizing their potential to address next-generation engineering challenges. These composites are particularly suited for critical applications, including lightweight, high-strength components in aerospace, wear-resistant parts in automotive systems, heat exchangers in marine environments, and durable materials for military-grade equipment. Key advantages include improved wear resistance, better thermal conductivity, reduced weight, and extended service life under extreme conditions. Future research opportunities focus on optimizing reinforcement ratios, refining fabrication techniques, and broadening the industrial adoption of these hybrid composites.

Keywords: SiC, Al2O3, graphite, aluminum metal matrix composites, aluminium hybrid composites.
