“…The reinforcement size and amount can also contribute significantly in the properties of the final product. However, in order to be fabricating AMMCs effectively the reinforcement choice and its cost, along with it application can also contribute in the manufacturing process [13][14][15]. Several ceramic particles have been fabricated successfully in the near past using different methods such as casting and powder metallurgy (PM), which involve mixing the powders, compacting followed by microwave sintering and extrusion [16,17].…”

In this study, Al-CeO2 nanocomposites containing various concentrations of reinforcement were fabricated by ball milling and microwave sintering process. A comparison of structural and mechanical properties of the developed nanocomposites is presented to elucidate the effect of reinforcement. Different characterizing tools such as X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM), surface profilometrer, microhardness tester and universal compression testing machines were employed. XRD and SEM/EDX analyses reveal the presence and uniform distribution of CeO2 nanoparticles into the Al matrix. A significant increase in microhardness and compressive strength is noticed with increasing concentration of CeO2 nanoparticles due to a dispersion hardening effect of the reinforcement. Our study indicates that the concentration of reinforcement has a significant influence of the properties of Al-CeO2 nanocomposites. It is further noticed that Al-2.0 vol.% CeO2 nanocomposite demonstrates the best performance as compared to pure Al and other developed nanocomposites.

Hybrid nanocomposites have emerged as a groundbreaking class of materials in the aerospace industry, offering exceptional mechanical, thermal, and functional properties. These materials, composed of a combination of metallic matrices (based on aluminum, magnesium, or titanium) reinforced with a mixture of nanoscale particles, such as carbon nanotubes (CNTs), graphene, and ceramic nanoparticles (SiC, Al2O3), provide a unique balance of high strength, low weight, and enhanced durability. Recent advances in developing these nanocomposites have focused on optimizing the dispersion and integration of nanoparticles within the matrix to achieve superior material performance. Innovative fabrication techniques have ensured uniform distribution and strong bonding between the matrix and the reinforcements, including advanced powder metallurgy, stir casting, in situ chemical vapor deposition (CVD), and additive manufacturing. These methods have enabled the production of hybrid nanocomposites with improved mechanical properties, such as increased tensile strength, fracture toughness, wear resistance, and enhanced thermal stability and electrical conductivity. Despite these advancements, challenges remain in preventing nanoparticle agglomeration due to the high surface energy and van der Walls forces and ensuring consistent quality and repeatability in large-scale production. Addressing these issues is critical for fully leveraging the potential of hybrid nanocomposites in aerospace applications, where materials are subjected to extreme conditions and rigorous performance standards. Ongoing research is focused on developing novel processing techniques and understanding the underlying mechanisms that govern the behavior of these materials under various operational conditions. This review highlights the recent progress in the design, fabrication, and application of hybrid nanocomposites for aerospace applications. It underscores their potential to revolutionize the industry by providing materials that meet the demanding requirements for lightweight, high-strength, and multifunctional components.
