Impact-resistant aluminum oxide surface enhanced thermal protection material and preparation method thereof
The invention discloses an impact-resistant aluminum oxide surface reinforced thermal protection material and a preparation method thereof, and relates to the field of thermal insulation materials, and the impact-resistant aluminum oxide surface reinforced thermal protection material comprises an impact-resistant aluminum oxide surface reinforced composite material layer and an internal thermal insulation core material. The impact-resistant aluminum oxide surface reinforced composite material comprises a composite material reinforced layer formed by sintering 5-50 layers of aluminum oxide fiber fabrics and a plurality of nano-powders, the inner heat insulation core material comprises a fiber composite heat insulation material and a nanometer heat insulation material. According to the method, multiple layers of aluminum oxide fiber fabric are compounded with multiple kinds of nano powder and laid outside an internal heat insulation core material, heating, pressurizing and densifying are conducted through a hot pressing bag, and finally sintering is conducted after demolding is conducted, so that near-net-size forming of the aluminum oxide surface reinforced composite material is achieved. The heat-proof layer with excellent impact resistance, oxidation resistance and ablation resistance can be effectively combined with the heat-insulating layer with good heat-insulating performance, so that the impact resistance of the surface is improved, and the safety of a heat protection system is guaranteed.
