Abstract Vehicles operating in space need to withstand extreme thermal and electromagnetic environments light of the burgeoning science technology. It is imperatively desired high insulation materials with lightweight extensive mechanical properties. Herein, a boron–silica–tantalum ternary hybrid phenolic aerogel (BSiTa-PA) exceptional stability, strength, low conductivity (49.6 mW m −1 K ), heightened ablative resistance prepared by an expeditious method. After extremely erosion, obtained carbon demonstrates noteworthy interference (EMI) shielding performance efficiency 31.6 dB, accompanied notable loading property specific modulus 272.8 kN·m kg . This novel design concept has laid foundation for development more complex environments.

Ceramic aerogels are promising high-temperature thermal insulation materials due to their outstanding stability and oxidation resistance. However, restricted by nanoparticle-assembled network structures, conventional ceramic commonly suffer from inherent brittleness, volume shrinkage, structural collapse at high temperatures. Here, overcome such obstacles, 3D ultralight highly porous carbon tube foams (CTFs) were designed synthesized as the carbonaceous precursors, where melamine used sacrificial templates form hollow thin-wall structures in CTFs (density: ∼4.8 mg cm-3). Then, arbitrary-shaped silicon carbide (SiC) nanofibrous (SNFAs) obtained through a simple chemical vapor deposition (CVD) process on CTFs. The resulting SNFAs exhibited excellent comprehensive performances: ultralow density (4.2 cm-3) conductivity (21.3 mW m-1 K-1 room temperature), rigidity (specific modulus: 13.2 kN·m kg-1), resilient compressibility. could support over 2100 times weight without visible deformation. Furthermore, also showed exceptional stability, which means that they withstand 1100 °C an air atmosphere 1550 inert atmosphere. These superior performances enable be suitable for harsh environments.
