Progress of the High-temperature Absorbers and Modified SiC Absorbing Performance

For the stealth demand on the high temperature places of the armament,high-temperature absorbers are discussed.High temperature absorbing materials are prerared using modified SiC absorbers.In the condition of the room temperature and 580 ℃ high-temperature,material reflectivity is less than-10 dB in the frequency range of(26.5~40) GHz.The material has excellent absorbing performance.
