摘　　要：比较了高温背景下各类吸波材料的特点,确定连续纤维增强陶瓷基复合材料是较理想的高温吸波材料体系。分析了常用陶瓷基复合材料中连续纤维以及陶瓷基体的介电性能,确定连续碳化硅纤维增强碳化硅基(SiCf/SiC)复合材料是目前较有前途的高温结构吸波材料。综述了高温结构吸波材料的国内外研究现状,重点介绍了国防科技大学的最新研究进展,最后讨论了高温结构吸波材料存在的问题。The features of several kinds of commonly used radar absorbing material structures are compared under high-temperature environment, and it is confirmed that the ceramic matrix composites are the most ideal radar absorbing material structure for high-temperature applications. The dielectric properties of the constituents of the ceramic matrix composites are analyzed, and it is pointed out that SiC fiber reinforced matrix （SiCf/SiC） composites are one of the most promising high-temperature structural radar absorbing materials. The recent development of high-temperature structural radar absorbing materials is reviewed briefly, and the progress in National University of Defense Technology is introduced mainly. Finally, the existing problems of high-temperature structural radar absorbing materials are discussed.
