Pushing the limits of microwave absorption capability of carbon fiber in fabric design based on genetic algorithm

The field of electromagnetic wave absorption (EWA) requires the adaptability, tenability, and multifunction high-performance materials in future. design preparation EWA aiming at performance requirements is latest research hotspot. Here, a performance-driven strategy for simultaneously coordinating different target performances was proposed to optimize structure periodical long continuous carbon/glass fiber fabric (PCGF) through algorithm simulation. optimized PCGF not only improves impedance matching, but also introduces induced orientation effect high cooperative loss conductivity, resonance, periodic structure. flexible shows broad effective bandwidth (EAB) 32.7 GHz covering part C-band whole X-, Ku-, K-, Ka-bands with thickness (d) 0.92 mm density 5.6×10?4 kg·cm?3. This highly designable promising practical application owing integrating characteristics good flexibility, acid alkali resistance, bending excellent mechanical properties, easy large-scale preparation.
