Abstract: The development of high-performance thermal insulation materials is of great significance to the development of aviation, construction, transportation and other fields. Silica (SiO2) fiber has the advantages of low density, low thermal conductivity and oxidation resistance, and is a kind of thermal insulation material with great development potential. However, the thermal conductivity of SiO2 fiber needs to be further reduced, so how to further improve its thermal insulation performance is an important topic. Based on the thermal insulation mechanism of SiO2 fiber, the preparation methods and research status of SiO2 fiber with different morphologies (solid, hollow, porous) are analyzed in this paper. The research progress of SiO2 fiber composite with organic materials, inorganic materials is aslo summarized. At the same time, the main application fields of thermal insulation materials are briefly described. Finally, the development direction of SiO2 fiber-based thermal insulation materials in the future is prospected.
