Space shuttle vehicles employ different thermal protection materials under varying conditions.This paper reviews five commonly used thermal protection materials:thermal protection coatings,thermal protection/structural integrated materials,thermal insulation tiles,flexible thermal protection materials,and honeycomb-reinforced ablation materials,summarizes their recent research progress,and offers recommendations for future development.Thermal protective coatings require further enhancement of resin high-temperature resistance;thermal protection/structure-integrated materials still face challenges in structural design,manufacturing,and failure mechanisms;insulating tiles need improved high-temperature mechanical performance and refined fabrication processes;flexible thermal protection materials,being foldable and adhesive,hold diverse application prospects;and honeycomb-reinforced ablative materials are lightweight and commonly used for large-area thermal protection on spacecraft.With the continual advancement of aerospace equipment,thermal protection materials are entering a major period of development.
