Description

technical field [0001] The invention belongs to the technical field of thermal protection materials for aviation and aerospace, and specifically relates to a high-temperature resistant wave-transmitting heat-insulating tile and a preparation method thereof. Background technique [0002] With the development of aerospace technology, the wave-transmitting cover or window of the aircraft will be subjected to harsh aerodynamic heating. In order to prevent the external heat from entering the interior through the wave-transmitting window or cover, and at the same time meet the normal flight and normal communication requirements of the aircraft, A high-efficiency heat-insulating tile with both high-temperature heat insulation and high-temperature wave-transmission functions must be placed inside the wave-transparent window or cover. [0003] Although some performance indicators of the existing thermal insulation tiles have reached a relatively high level, the comprehensive indicato...
