Current Situation Development of Lightweight Ablation Materials for Thermal Protection

Abstract

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 silicone resin reinforced with glass，silica or carbon fiber/phenolic honeycomb as well as silicon，phenolic and Silicone Impregnated Reusable tendency Ceramic Ablator(SIRCA) and Phenolic Impregnated Carbon Ablator( in the future of aboard lightweight ablators is proposed，which can PICA)，finally the development directly borrow or simply draw inspiration for our country in this field.
