High-temperature-resistant heat-insulation sandwich structure ceramic-based composite material and preparation method thereof
The invention discloses a high-temperature-resistant heat-insulation sandwich structure ceramic-based composite material and a preparation method thereof. The composite material adopts a sandwich structure, the thickness of an upper surface layer is larger than that of a lower surface layer, and a high-temperature-resistant modified aluminum fiber reinforced Al2O3 aerogel composite material is used as a core layer to obtain better heat insulation performance. The silicon carbide ceramic matrix composite reinforced by the carbon fiber fabric is used as a hot surface to bear a heat-proof task and resist a continuous high-temperature environment, the combination of the core layer and the hot surface layer has good heat-resisting and heat-insulating effects, and the heat and the temperature are obviously reduced when reaching a cold surface; the high-temperature resistance of the high-temperature-resistant heat-proof and heat-insulation sandwich structure ceramic-based composite material is remarkably improved, the heat-proof and heat-insulation effects of the ceramic composite material can be remarkably improved, and the safety performance of an aircraft is improved; the preparation method is mature in preparation process, high in production efficiency and simple to operate, and has a wide prospect in large-scale production and preparation of the ceramic-based composite material in the industrial field.
