Abstract: Ceramic fiber insulation tiles have the characteristics of low density, high temperature resistance, low thermal conductivity and excellent wave transmission performance. It is suitable to be used as thermal protection material in medium low temperature area of space vehicle. The application of high emissivity coating on the surface of ceramic fiber insulation tiles can effectively solve the problems of easy moisture absorption, low strength and easy performance degradation in the service process of ceramic fiber insulation tile. At the same time, it can block the high temperature erosion airflow and improve the energy reflectivity and thermal shock resistance. This paper mainly introduces the preparation methods of ceramic fiber insulation tiles and the influencing factors of their properties, summarizes the research progress of ceramic fiber insulation tiles and their high emission coatings in aerospace field, and looks forward to their future development.

Key words: ceramic fiber, insulation tile, high emissivity coating, insulating material, high temperature resistance
