Abstract
Traditional fiber-reinforced composites with single-layered electrical conductivity (EC) face limitations with respect to electromagnetic wave absorption (EWA) bandwidth and strength. This study introduces a novel Cf/SiCf/Si3N4f layered composite (multifiber layered composite, MFLC), prepared via fiber alignment and curing, which capitalizes on the distinct ECs of carbon fibers (Cf), silicon carbide fibers (SiCf), and silicon nitride fibers (Si3N4f) to address these limitations. The Si3N4f layer enhances the impedance matching, deepening EW penetration and curtailing reflection. The conductive Cf and SiCf layers lead to substantial energy dissipation through conduction loss. Electric field simulations confirmed the regulatory effect of Si3N4f layer on EC, thereby facilitating the optimization of impedance matching. MFLCs achieved a minimum reflection loss of −68.52 dB and an effective absorption bandwidth of 8.23 GHz in the X–Ku band. The optimally matched composites demonstrated exceptional EWA performance, attaining the radar cross section reduction of up to 149.9%. The MFLCs hold significant promise as a novel class of lightweight, highly efficient, and wide-bandwidth EW absorbers.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
