Abstract
The development of aluminium metal matrix composites (AMMCs) has seen significant advancements in recent decades. This progress has been driven by industry demands for lighter yet stronger materials. This article provides a comprehensive review of the challenges and opportunities in the recent developments of AMMCs, covering methods, applications, and general testing. The main challenges in the fabrication of AMMCs include manufacturing processes, control of reinforcement particle distribution, wettability control of aluminium, microstructural homogeneity, selection of efficient and economical methods, and issues related to corrosion and wear resistance. The agglomeration of reinforcements due to the low wettability of aluminium remains a major issue in AMMCs, leading to poor mechanical properties and accelerated corrosion. On the other hand, technological advancements in nanocomposites, additive manufacturing techniques, and modern casting methods such as stir casting have opened new opportunities to enhance the performance and applications of AMMCs across various sectors, including defense, automotive, aerospace, and construction industries. This review aims to provide insights for researchers and practitioners in the development of AMMC materials, offering perspectives on overcoming existing challenges and leveraging emerging opportunities for further innovation
