As aerospace technology advances toward higher speeds and longer flight durations, aircraft face new thermal challenges in extreme environments. Conventional thermal protection systems are no longer sufficient to meet the requirements of these applications. Therefore, there is an urgent need to conduct research on the design and manufacturing of novel thermal protection systems. In line with the trend toward integrating thermal protection and insulation, thermal insulation materials must possess excellent thermal insulation, high temperature resistance, and mechanical properties. Both porous ceramics and aerogels present significant performance trade−offs, making it imperative to optimize their comprehensive properties of these materials to meet the requirements of extreme applications. This article systematically reviews the research progress on oxide porous ceramics and aerogels as high−performance thermal insulation materials, and details their material characteristics, preparation methods, thermal insulation performance, mechanical properties, and high−temperature resistance. Through strategies such as compositional design, fiber reinforcement, and structural regulation, the thermal insulation and mechanical properties of oxide porous ceramics and aerogels can be tailored, endowing them with broad application potential in thermal protection systems for extreme environments.
