Ceramic aerogel flexible insulation material applied to the research progress of aerospace
Traditional ceramic based or resin based corrosion and heat resistant materials cannot fully utilize the ad-vantages of material ablation and heat absorption,and their thermal conductivity and density are relatively high,re-sulting in poor ablation deformation,which affects the maneuverability of aircraft.In addition,traditional resin based ablative heat-resistant materials may experience severe aerobic erosion in aerobic environments.Ceramic tile based non ablative materials have high brittleness,poor damage resistance,high preparation and maintenance costs,and are difficult to adapt to the large-area heat protection of the new generation of aircraft.Therefore,it is necessary to develop ceramic aerogel flexible materials with low density,near zero ablation in long-term aerobic en-vironment,and integration of long-term thermal protection and insulation to meet the needs of future aircraft overall thermal protection materials.This review summarizes the research progress of aerogels and ceramic fiber materials in the aerospace field,in order to provide reference for related research.
