摘　　要：多层隔热(MLI)结构在高真空环境下具有极低热导率,主要用于太空环境下飞行器和大型燃料贮箱的隔热。本文对MLI结构的隔热原理、选材、制备工艺及应用等进行了综述,简要介绍了国内外MLI结构的研究进展和发展趋势,提出进一步改进MLI的性能是我国实现飞行器长期在轨运行和深空探测的重要研究方向。Multi-layer insulation structures（MLI） are a kind of composite mostly used as thermal insulation of the aerocraft and propellant tank in the space. In this paper, heat insulating principle, composition, processing technology and the application of MLI are reviewed. The recent the progress and tendency of MLI is introduced briefly. With the purpose of landing on moon and deep space exploration,the property of MLI must be improved.
