“…[20] established multifunctional modeling and control of panel flutter stability in piezoelectric functionally graded materials under joint thermal-electrical-aerodynamic loads, where actuation authority improves but degrades at elevated temperatures. [21] highlighted the aeroelastic tailoring potential of graphene platelet reinforcement in graded Aluminium panels to simultaneously enhance structural and aerodynamic metrics. [22] found stability and vibration response of sandwich plates with porous cores depends on foundation interactions and internal material tailoring provides optimization opportunities.…”

In this paper we will demonstrate the possibility of weight optimization of panels under aero-thermal loading in hypersonic flow using functionally graded materials (FGM). The in-plane volume fraction of two constituents (Aluminium and Nickel) is modelled using polynomial distributions. Different material grading layouts are investigated, including cases with Nickel concentrated at corners, sides, midpoints and center. The solution of the problem utilized a higher order element with C1 continuity. The study covers the linear boundaries of the panel flutter problem as well as the non-linear post-buckling deflections. The results indicated Nickel placement strategies are shown to enhance dynamic pressure and vibration performance for a given mass reduction through optimal center and edge localization. Overall, the integrated modelling approach demonstrates the potential to systematically optimize stability, weight and integrity in hypersonic flow to optimize the weight of panels subject to aero-thermal loads.

“…Furthermore, centrifugal casting processes offer a continuous gradient and cost-effective approach for creating FGMs when compared to other techniques [20][21][22]. Among the various matrix materials available, aluminum alloys are widely used in the production of FGMs and have reached the industrial level of development [23,24]. Various ceramic particles, including SiC, B 4 C, Al 2 O 3 , zircon, and TiC, have also been utilized to reinforce Al alloy for the production of graded composites [25,26].…”

In this study, an optimization approach was employed to determine the optimal main parameters that improve the performance of functionally graded composites manufactured using a combination of stirring and horizontal centrifugal casting. Pure aluminum reinforced with silicon carbide particles was used as the material for the composites. The effects of key input parameters such as mold speed, pouring temperature, stirring speed, and radial distance were optimized using a combination of grey relational analysis and response surface methodology. The statistical significance of the predicted grey relational grade model was assessed through an analysis of variance to identify the appropriate main parameters. The results showed that radial distance had the greatest impact on the performance of the composites, followed by pouring temperature. The optimal combination of main parameters was determined to be a mold speed of 1000 rpm, a pouring temperature of 750 °C, a stirring speed of 150 rpm, and a radial distance of 1 mm. Confirmation tests using these optimal values resulted in a 54.69% improvement in the grey relational grade.
