Aluminium matrix composites are increasingly sought after in engineering due to their high strength-to-weight ratio and versatile performance characteristics. Fabrication relies on primary synthesis methods across solid-state processes, such as powder metallurgy and three-dimensional printing, and liquid-state routes, including casting and pressure infiltration. These composites incorporate diverse reinforcement types, spanning synthetic ceramics to agro-based ceramic materials. Following primary fabrication, secondary processes such as heat treatment, forging, and other thermomechanical methods are employed to enhance material properties. While individual production and treatment methods offer distinct benefits alongside specific drawbacks, current evidence remains scarce regarding the combined use of multi-synthesis pathways and multiple secondary treatments. Addressing these gaps in hybrid processing strategies presents significant scope for optimising composite manufacturing.
Modern engineering sectors require materials that deliver high strength without adding unnecessary weight. Understanding how different manufacturing and post-processing methods affect aluminium matrix composites helps engineers design more resilient components. It also supports the integration of sustainable options, such as agro-based ceramics, into high-performance materials suitable for demanding environments.
These composite processing techniques target manufacturing sectors including automotive, aerospace, marine, and armoury production. Because the review identifies significant gaps in multi-route synthesis and combined secondary processing, the underlying technology remains at an early applied research stage. Industrial uptake depends on resolving technical trade-offs between primary synthesis methods and establishing multi-step secondary treatments for consistent material performance.

In this paper, the primary synthesis and secondary treatment of Aluminium matrix composites (AMCs) has been reviewed. The renewed quest for component materials with high strength-to-weight ratio, unusual and superlative combination of properties for applications in automotive, aerospace, marine and warfare armoury manufacturing industries has increased the versatility potential of aluminium alloy-based composites. Several categories (synthetic and agro-based ceramics) of reinforcement materials for aluminium composite are discussed. The manufacturing/fabrication techniques which could be solid phase (powder metallurgy and rapid prototyping or 3 D printing method) or liquid phase (casting and pressure infiltration) methods are discussed in this review work. Secondary treatment such as heat treatment, forging and other thermomechanical treatments which improves the properties of as-synthesized composites are also discussed. A review synopsis of recent studies provides opportunity for concise but a more robust understanding of potential benefits and detrimental effects associated with the use of various primary synthesis routes and secondary treatment for manufacturing of ceramic reinforced AMCs. Despite the laudable research efforts that have been made towards development and enhancement of the properties of AMCs, this review work revealed that literature is very sparse on synergetic adoption of multi-synthesis route and multi-approach secondary treatment for producing AMCs. Sequel to the aforementioned unexplored research concept, some lacunae are identified and suggested for further elaborations and study.
