Abstract In order to improve the mechanical strength of traditional aerogel materials,, preparation and application of the anti-ablation aerogel material with sandwich structure were studied. The densification technolgy of panel and Z pin connection technology of sandwich structure were broken through. Thus, The mechanical strength of the panel material was steadily increased, after the study of densification parameters, such as impregnation method, concentration of ceramic precursor, impregnation times. The strain coordination performance was greatly improved, with deflection of the center point about 8.5 mm, after the preparation of fiber preform with different density fiber in the Z direction. It demonstrated the excellent insulation performance and mechanical bearing capacity.
