Abstract: Aluminum oxide (Al₂O₃) has emerged as a prominent filler in polymer composites, enhancing mechanical, thermal, and electrical properties. This review critically examines recent research on Al₂O₃-reinforced epoxy, thermoplastic, and hybrid composites, with particular emphasis on particle modification, dispersion, and interfacial compatibility. Mechanical properties, including tensile, flexural, and impact strength, are analyzed alongside thermal conductivity, thermal stability, and glass transition temperature. Functionalization of Al₂O₃ particles, such as silane treatment or hybridization with graphene oxide, significantly improves filler-matrix adhesion, optimizing both stiffness and toughness. The review highlights the trade-offs between enhanced thermal performance and reduced ductility at higher filler loadings. Advances in fabrication methods, including melt compounding, hand lay-up, and bio-inspired approaches, are summarized. This work provides a comprehensive reference for researchers seeking to design high-performance Al₂O₃ polymer composites for structural, thermal management, and electronic applications.
