Research progress of ceramic matrix composites for high temperature stealth technology based on multi-scale collaborative design

Abstract

Thermal structural materials integrated with specific electromagnetic function have arised great attention in recent years. Driven by the urgent demand of multi-functional composites involving oxidation resistance, high strength and strong microwave attenuation in application of future high speed stealth vehicle, ceramics and their derivative architectures have considered to be a promising candidate in the field of high-temperature microwave absorption (HTMA) owning to tunable dielectric properties as well as intrinsic excellent thermo-physical properties. This article mainly systematically summarizes state-of-art research progress of high temperature stealth performance of ceramic matrix composites from multi-scale collaborative design. Specifically, the influence on microstructure of SiC fibers, interfaces, matrix and meta-structure design on the microwave absorbing are summarized. Besides, compatibility design over microwave and infrared range of ceramic matrix absorbing composites are summarized. Finally, the prospects in the future challenges and guidelines are provided to design more novel functional high temperature stealth materials. Looking forward to the development trend of high-temperature stealth technology of ceramic matrix composites, it is proposed that the more attention should be devoted to combination of structural and functional performance in terms of compatibility stealth materials with strong absorption, wide frequency bandwidth, multi-frequency absorption, high temperature resistance and low density in application of high temperature stealth materials in the future.
