Abstract
AbstractMeasuring silicon carbide (SIC) fibers is a widely used technique in searching for SIC materials with high absorbing properties. Nevertheless, obtaining reasonable electromagnetic properties in most of the existing experimental setups with SIC fiber materials remains difficult. Additionally, being a critical load‐carrying component of composite materials, the properties changing during oxidation conditions would directly impact the practical application of SIC fibers. Aiming at solving such problems, this paper investigates and analyzes the variation of electromagnetic performance under different oxygenation times for SIC fabric cloths (provided by Aerospace 703) and uses separated cylindrical resonant cavities to investigate SIC fiber cloths' electromagnetic properties. Eventually, testing results indicated that the dielectric constant decreases with the increase in oxidation time for SIC fiber cloths. The findings presented here are of guiding significance toward applications of SIC fibers in high temperature conditions.
