Preparation method and application of ultra-thin carbon-ceramic composite material spray pipe extension section
The invention provides a manufacturing method and application of an ultra-thin carbon-ceramic composite material spray pipe extension section, and belongs to the technical field of carbon fiber composite material preparation. The spray pipe extension section is of a thin-wall rotary body structure and has the bell jar type appearance characteristic, and near-net-size forming of the spray pipe extension section is achieved through deformation control and deformation compensation in the manufacturing process. The prepared carbon-ceramic composite material nozzle extension section has the characteristics of light weight, low porosity, excellent mechanical property, uniform ceramic phase distribution, high thermal stability, high environmental applicability and the like, has the advantages of simple process, convenience in operation, short period, low comprehensive cost and the like, and can be applied to new-generation high-performance solid/liquid rocket engine nozzle extension sections.
本发明提供了一种超薄碳‑陶复合材料喷管延伸段的制造方法及应用，属于碳纤维复合材料制备技术领域。本发明提供的喷管延伸段为薄壁回转体结构，具有钟罩型外形特征，制造过程中通过变形控制和形变补偿实现了喷管延伸段的近净尺寸成型。本发明制备的碳‑陶复合材料喷管延伸段具有质量轻、孔隙率低、力学性能优良、陶瓷相分布均匀、热稳定性及环境适用性强等特点，具有工艺简单、操作方便、周期短、综合成本低等优势，可应用于新一代高性能固体/液体火箭发动机喷管延伸段。
