摘要：

The connection between the external thermal insulation layer and the internal cold structure of the body generally needs to be made with thermal insulation materials in the thermal protection system of the high-speed aircraft. Insulation materials are desigened to bearing load while maintaining their advantageous of excellent thermal insulation properties in the field of high temperature industry. Heat insulation materials with high-temperature performance, high strength and low thermal conductivity have board application prospects. Porous ceramics are widely used in the field of insulation due to their unique porous structure, high posity and low thermal conductivity. Howe-ver, the low strength of porous ceramic materials restrict the application because of the high posity. At present, lots of researches endeavors to seek fiber reinforced ceramic and optimize porous ceramic fabrication process, aiming at increasing strength of porous ceramic while reducing the thermal conductivity. Several research groups have reported the fiber reinfrced ceramic matrix conposites and fibrous porous ceramic are presented an excellent mechanical property and low thermal conductivity. Among porous ceramic matrix composites with low thermal conductivity, fiber-reinforced nanopore aerogel thermal insulation composites have unique nanopore structure, high porosity, low thermal conductivity and strength. Fiber porous ceramics with high porosity, high strength and high temperature performance, but its thermal conductivity is higher than that of aerogel composites. Fiber reinforced oxide ceramic matrix composites have low porosity, excellent strength and high temperature resistance, but its thermal conductivity is too high. This review offers a retrospection of the research efforts with respect to the high-temperature performance and high strength insulation compo-sites, and provides elaborate descriptions about the structure of the fiber reinforced aerogel insulation composites, the fibrous porous ceramic and fiber reinforced oxide ceramic matrix composites. We then pay attention to the problems confronting the current high-temperature performance and high strength insulation composites. © 2020, Materials Review Magazine. All right reserved.
