本文对绝热壳体和喷管的选材、材料特性、应用现状和展望进行了阐述。如能用陶瓷/陶瓷类或碳基类材料代替固体火箭发动机中尚用的小量金属结构材料,固体火箭推进系统的全复合材料化就能实现。 In this paper, the selection of insulating shell and nozzle, material properties, application status and prospects are described. If the ceramic / ceramic or carbon-based materials can be used to replace solid metal rocket engine is still a small amount of metal structure material, solid rocket propulsion system can be realized by all-composite material.
