A dual-network architecture is formed through hydrogen bonding and electrostatic interactions, yielding a highly porous structure with integrated strength, flexibility, and electrical functionality. The aerogel exhibits an exceptional compressive stress of 0.48 MPa at 60 % strain, broadband shielding effectiveness exceeding 90 dB in the X-band (with &gt;90 % absorption contribution), and thermal stability up to 150 °C. Conventional shielding metrics based on continuous-wave (CW) frequency-domain evaluations often fail to capture material behavior under such scenarios. To evaluate the aerogel's transient protection capabilities, we further employed time-domain shielding effectiveness (TDSE) simulations based on finite-difference time-domain (FDTD) modeling. The results confirm strong suppression of electric field peaks, derivatives, and energy flux under EMP-like illumination, demonstrating the aerogel's viability in pulse-rich environments such as aerospace and defense systems.

To address this issue, we propose a dual-scale framework (FEM-SCA) that integrates the finite element method (FEM) with self-consistent clustering analysis (SCA). At the macroscopic level, FEM captures the overall thermo-mechanical response, while nested mesoscale representative volume elements (RVEs) are solved using the SCA to capture dissipative processes, including heat radiation, phenolic resin pyrolysis, thermal blocking, silica fiber phase transitions, carbon-silicon reaction, and mechanical degradation. A staggered incremental scheme enables efficient transient coupling across scales.

Experimental results revealed that the 3D braided carbon fiber-reinforced composite specimens exhibited approximately linear elastic behavior during torsion. An increase in braiding angle (15°–45°) enhanced shear modulus and strength by 67 %, but reduced failure strain to 0.61 % while shifting the failure mode dominance from ductile matrix deformation to brittle fiber fracture. CT analysis demonstrated that compressive fiber bundle failure governed mechanical performance, with damage progression initiating as interfacial debonding (at 60 % load), progressing through crack bifurcation (at 80 % load), and culminating in fiber buckling failure. 3D-DIC quantitatively characterized the strain heterogeneity regulated by braiding topology, showing that maximum shear strain decreased by 67 % with increasing braiding angles. Notably, 45° specimens developed mesh-like strain distribution pattern, revealing the directional regulation of load transfer paths through spatial fiber entanglement. The proposed AE signal processing framework integrating Hilbert-Huang transform with frequency-domain calibration techniques successfully identified three characteristic damage modes: matrix cracking (100–200 kHz), interface debonding (200–320 kHz), and fiber fracture (320–420 kHz).

NPCs with varying ablation layer thickness ratios (13 %, 33 %, and 53 %) are fabricated and systematically evaluated through macro-micro mechanical tests, heat transfer test, and systematic high-temperature ablation experiments. Results show that NPC with a 33 % ablation layer ratio achieves the highest tensile strength (42.6 ± 0.82 MPa), owing to an optimal balance between load-bearing capacity and strain tolerance. In-situ micro-CT analysis under tensile loading reveals that the high-density ablation layer significantly enhances both strength and ductility by providing tightly woven fiber yarns. Heat transfer simulations indicate that the high-density layer serves as the primary heat conduction path, while the low-density layer effectively reduces overall thermal conductivity by limiting solid fiber heat transfer. Oxy-acetylene ablation tests at 2000 °C and 3200 °C demonstrate that the dual-layer structure reduces the linear ablation rate by approximately 25 % compared with single-layer NPCs, as the tightly woven ablation layer effectively withstands extreme heat flux.

The synthesized FPEKC exhibited outstanding thermal stability (T_{-5 %} = 500.45 °C), ensuring excellent structural integrity throughout typical composite processing conditions (∼380 °C).

The intrinsic structural compatibility between FPEKC and the PEEK matrix facilitated extensive molecular diffusion and interchain entanglement at the interface. Additionally, the introduction of graphene oxide (GO) nanosheets into the FPEKC slurry established robust chemical interactions at the fiber-matrix interface, including hydrogen bonds and π-π stacking, as well as nanoscale mechanical interlocking, achieving multi-scale interface enhancement.
