This work analyzes the application of metal-organic gels (MOGs) as innovative structural precursors for the fabrication of nanostructured carbon aerogels. The investigated aerogels, developed in FeCo/NC and FeCo/Fe3O4/NC formulations, offer excellent performance in electromagnetic wave absorption (EMWA) and thermal insulation, synergistically combining strong electromagnetic attenuation and radar stealth properties verified and validated through computer simulations focused on the reduction of the Radar Cross Section (RCS). Owing to their extraordinary structural lightweightness, optimal impedance matching, and high versatility at reduced thicknesses, they prove ideal for advanced military applications, particularly in stealth technology and low-observable systems for next-generation aerospace vehicles.
L'elaborato analizza l'applicazione di gel metallo-organici (MOG) come precursori strutturali innovativi per la realizzazione di aerogel di carbonio nanostrutturati. Gli aerogel in questione, sviluppati nelle formulazioni FeCo/NC e FeCo/Fe3O4/NC, offrono prestazioni eccellenti nell'assorbimento delle onde elettromagnetiche (EMWA) e nell'isolamento termico, combinando in modo sinergico una forte attenuazione elettromagnetica e proprietà stealth radar verificate e validate tramite simulazioni computerizzate incentrate sulla riduzione della Radar Cross Section (RCS). Grazie alla loro straordinaria leggerezza strutturale, all'ottimale adattamento di impedenza e alla spiccata versatilità di impiego a spessori ridotti, si rivelano ideali per applicazioni militari avanzate, in particolare nella tecnologia stealth e nei sistemi a bassa rilevabilità per velivoli aerospaziali di prossima generazione.

Owing to their extraordinary structural lightweightness, optimal impedance matching, and high versatility at reduced thicknesses, they prove ideal for advanced military applications, particularly in stealth technology and low-observable systems for next-generation aerospace vehicles.| File | Dimensione | Formato | |
