摘要
随着我国航空航天和国防事业的极速发展,透波陶瓷材料成为了高马赫数飞行器天线罩、雷达天线窗等关键部件的重要候选材料,是当前材料领域的研究热点之一。本文根据高温高超声速应用场景对透波陶瓷材料的基本性能要求,概述了透波陶瓷材料的发展历史及国内外研究现状,结果表明:均质陶瓷材料因较差的介电性能和高温机械性能等问题面临淘汰,石英纤维织物增强石英复合陶瓷是已投入应用,综合性能最优的高温透波材料。目前透波陶瓷材料仍存在介电性能和机械性能难以协同、透波性能和隔热性能矛盾及成型加工困难等问题,高性能多元氮化物陶瓷和连续纤维增强氮化物基陶瓷是今后高温透波陶瓷材料的发展方向。
With the rapid development of aerospace and national defense of China,wave-transparent ceramic materials have become significant candidate materials for key components,such as the radome and radar antenna window,of high Mach number aircraft,and it is also one of the research hotspots in the field of materials.According to the basic performance requirements of high-temperature and hypersonic application scenarios on wave-transparent ceramic materials,this paper summarizes the development history and domestic and overseas research status of wave-transparent ceramic materials.The results show that homogeneous ceramic materials are facing elimination due to their poor dielectric properties and high-temperature mechanical properties,whereas quartz fiber-reinforced quartz composite ceramic is the high-temperature wave-transparent material that has been put into use and has the optimal comprehensive performance.At present,wave-transparent ceramic materials are still faced with problems such as the difficult coordination between dielectric and mechanical properties,the contradiction between wave-transparent properties and heat insulation properties as well as difficult molding and processing.High-performance multi-component nitride ceramic and continuous fiberreinforced nitride-based ceramic are the future development directions of high-temperature wave-transparent ceramic materials.
