Abstract: Future new space vehicles, characterized by fast flight speed and long navigation time, have become an important research hotspot for the world’s space powers. In order to guarantee the safe flight of the vehicle under aerodynamic heating conditions for a long time, the application of anti-insulation composite materials plays a crucial role. At present, in view of the weak interlayer performance and low preparation efficiency of heat protection composites for space vehicles, and the weak core material performance of heat protection ceramic-based composite sandwich structure and hand-stitching enhancement, the article analyses and summarizes the current research status of domestic and foreign research on heat protection composites and Z-pin enhancement technology from the aspects of design, preparation and application, and puts forward the development trend of China’s future Z-pin enhancement technology of heat protection composites.
