A Review of Ablative Materials and Ablative-Resisting Phenolic Resins

Introduces three shelter methods for high temperature environment used in spacecraft and solid rockets. Ablation is one of the methods that receives the widest applications.The usage, types and methods of evaluation of ablative materials are explained and the ablative performances of polymers in ablative materials are compared. Conclusions show that phenolic resins have fairly good overall ablative performance. A Classification and brief introduction are made for the references to ablative phenolic resins obtained by consulting. Finally, the tendency of ablative polymers and the author's development work in ablative phenolic resins are introduced.
