Graphene-Ceramic Reinforced Hybrid Aluminium Nanocomposites: Multiscale Modelling

We comprehensively examine the selection, performance, and mechanical behaviour of graphene and ceramic-reinforced aluminium matrix nanocomposites (AMNCs), with a particular focus on graphene and ceramic hybrid aluminium nanocomposite (GCHANs). We explore the impact of various ceramic reinforcements and graphene on improving mechanical attributes such as strength, hardness, and wear resistance. Key challenges are addressed, such as particle agglomeration and voids, which often lead to premature failure in AMNCs, emphasizing the critical role of particle distribution and bonding within the matrix. A multiscale approach integrating both simulation and experimental data is reviewed to analyze the microstructural behaviour, mechanical stress distribution, and failure mechanisms of GCHANs. From different computational methods, the finite element analysis (FEA) technique is highlighted, showcasing its utility in optimizing the design and predicting the behaviour of AMNCs under different loading conditions. Besides FEA, other simulation techniques are also mentioned to capture nanoscale interaction and simulate material behavior, including molecular dynamics and micromechanical modeling. We also delve into analytical modeling, stiffness, governing properties, and various applications of GCHANs. Leveraging simulation models, we seek to provide deeper insights into the load-transfer mechanisms and defect management, offering potential pathways for precise optimization and broader applications of these advanced nanocomposites.
