高温吸收剂研究进展及改性碳化硅吸波特性

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

针对装备高温部位雷达隐身需求,论述了高温吸收剂的研究现状和最新进展。采用改性碳化硅高温吸收剂,制备了高温吸波材料,在室温和580℃高温下,材料在26.5～40GHz频段内的反射率均小于-10dB,具有良好的吸波性能。

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 refteetivity is less than --10 dB in the frequency range of （26. 5-40） GHz. The material has excellent absorbing performance.
