摘要

The unique advantages of heterogeneous interface engineering and its superior electromagnetic properties provide new momentum for designing advanced wave-absorbing materials. Most researchers focus on enhancing wave-absorbing capabilities by increasing interfacial polarization, often overlooking material cost and engineering feasibility. To address this, we enhance the heterogeneous interfaces of SiC/C nanofibers (NFs) by loading cobalt ferrite nanoparticles (CFO NPs), exploring a simple, cost-effective strategy to develop high-performance wave-absorbing composites. By adjusting the CFO concentration, we optimize the dielectric and magnetic losses of the composite to achieve impedance matching and improve absorption performance. The results show that the SiC/C/CFO20 composite exhibits excellent microwave absorption (MA), achieving a reflection loss (RL) value of −56.52 dB at 11.60 GHz with a matching thickness of 2 mm and an effective absorption bandwidth (EAB) of 5.05 GHz. Furthermore, the composite shows outstanding performance in both monostatic and bistatic radar cross section (RCS) simulations, with optimal values reaching −49.04 and −51.16 dB, respectively. This performance demonstrates a wide detection angle, supporting its potential for practical engineering applications. Overall, this approach provides a new perspective for designing high-efficiency, low-cost, and scalable wave-absorbing materials for engineering applications.
