Wave-absorbing Structural Ceramic Matrix Composites

With the rapid development of radar detection technology, materials with wave-absorbing and load-bearing performance are needed in order to satisfy the stealth requirements of aerospace vehicle key thermal structures. It is thus necessary to develop the high-temperature wave-absorbing structural materials. In this paper, the wave-absorbing matching principles (impedance matching and attenuation principles) and mechanical matching principles (elastic modulus matching, interfacial debonding and thermal expansion coefficient matching principles) of the wave-absorbing structural composites were introduced. Recent development of the high-temperature wave-absorbing structural ceramic matrix composites was reviewed. In addition, the development trend of designing absorbing structural materials with excellent properties according to the wave-absorbing and mechanical matching principles was also prospected.
