Research progress of high temperature microwave-absorbing ceramic matrix composites

Abstract

Microwave-absorbing ceramic matrix composites play an important role in the development of heat-resisting stealthy materials due to their excellent high-temperature mechanical property, superior corrosion resistance and oxidation resistance. In this paper, the micro to macromultiscale design principle of microwave-absorbing ceramics is introduced. The latest research progresses of microwave-absorbing materials such as modified SiC ceramics, doped BaFe₁₂O₁₉ (BFO) ceramics, polymer derived ceramics (PDCs), 3D printed porous ceramics/ceramic-honeycombs, multiscale-designed continuous fiber reinforced ceramic matrix composites (CFCMC) and other new ceramic matrix composites are overviewed. The development trend of ceramic matrix composites with integrated structure absorbing is prospected, and the fiber reinforced ceramic matrix composites with multiscale structure design of micro-macro is proposed to be an important development direction in the field of high-temperature stealth materials in the future.
