We present a new developed technology of producing a lightweight thermal insulation material made of fibers. It is based on silicon oxide with a diameter of 2…3 μm and a binder of silica for the heat protection of reusable space vehicles at outer surface temperatures not exceeding 1100 °C. The heat-insulating tiles have been obtained by forming a hydro-mass in a vibration-forming unit. The physics-mechanical and thermo-physical properties of the material are determined and described as well.
