Abstract

This article investigates the electromagnetic wave-absorbing properties of SiC-based ceramic woven fabrics. The electrical conductivity of ceramic woven fabrics was modified by heat treatment in air, resulting in oxidation, and the electromagnetic wave absorption potential of single- and double-layer ceramic woven fabrics were determined in the 17–40 GHz frequency range using the free-space method. The absorption potentials of ceramic woven fabrics of different chemical composition and weave were correlated with their material properties through X-ray diffraction, scanning electron microscopy, and electrical resistance measurement. The effect of the different arrangements of fabrics in multilayer forms, and how oxidation affects the electromagnetic wave absorption potential of the fabrics are discussed. Various double-layer combinations of SiC-based woven fabrics revealed promising potentials for both reduced reflection and transmission, resulting in ~90% absorption in the GHz range, which makes them powerful candidate materials for electromagnetic wave absorption applications.
