Abstract In contemporary times, radar and infrared‐compatible stealth materials have emerged as a pivotal domain of research globally, aimed at augmenting the survivability military assets. However, current candidates generally exhibit subpar compatibility performance in elevated temperature environments due to imbalanced interplay between two spectral bands. this work, meticulously designed sandwich‐structure SiO 2 /C@SiC/SiO composite is proposed cope with challenge. The middle layer C@SiC composites possesses excellent microwave absorption even high temperatures. outer layers aerogels serve not only inhibit infrared radiation intensity, but also reinforce capacity by optimizing impedance matching reducing heat transferred layer. Based on numerical simulation outcomes, thickness each has been optimized attain harmonious balance properties. Ultimately, sandwich structured demonstrate low RL (reflection loss) values (←5 dB) across nearly entire X band (8–12 GHz), alongside minimal surface temperatures hovering ≈44 °C an ambient 200 °C. comprehensive investigation into impact patterns underlying mechanisms offers invaluable insights develop for high‐temperature applications, which can be applied coatings skin Mach number aircraft.

Abstract Flexible and lightweight polypyrrole nanotubes/ethylene propylene diene monomer (PPyNT/EPDM) rubber foams with excellent electromagnetic waves (EMW) absorption performance in the X‐band were prepared via a simple chemical foaming method. By adjusting content of PPyNT, cellular structure, density, EMW properties PPyNT/EPDM can be precisely tailored. The synergistic effect structure an optimal PPyNT (15 phr) endows foam impedance matching high attenuation capacity, turn resulting X‐band, demonstrated by minimum reflection loss (RL min ) −27.01 dB at thickness 2.3 mm maximum effective bandwidth (EAB) 3.4 GHz 2.6 mm. Furthermore, this composite exhibits characteristics density only 0.795 g/cm 3 . Hence, research presents promising approach for commercial development flexible, lightweight, cost‐effective, highly efficient materials. Highlights Lightweight absorption. Tailored porous content. Foam 15 phr achieves RL EAB GHz. Synergy matching, conduction loss, multiple reflection.
