In view of demand of lighter thermal protection system for our national space vehicle,recent development of investigation and practical application of lightweight thermal protection ablation materials are summarized systematically at home and abroad,in which the silicon or resin reinforced with honeycomb structural reinforcement and resin impregnated fibrous substrate ablators are included,focuses on silicon,phenolic and silicone resin reinforced with glass,silica or carbon fiber/phenolic honeycomb as well as Silicone Impregnated Reusable Ceramic Ablator(SIRCA) and Phenolic Impregnated Carbon Ablator(PICA),finally the development tendency in the future of aboard lightweight ablators is proposed,which can directly borrow or simply draw inspiration for our country in this field.
