摘　　要：本文介绍了一种大长径比复合长尾管整体制备过程。对其材料选择、模具设计、工艺制作技术进行了详细讨论。整体成型的长尾管通过复合缠绕方式将碳/碳喉衬与钨渗铜喷管组件黏结包裹在尾管绝热层内部。与传统的长尾管制作工艺相比,此成型方法减少了各零部件之间的粘接界面,提高了产品的生产效率与质量可靠性,保证了复合材料尾管绝热层、喉衬与喷管的整体性,提高了产品的抗冲刷性能。A integral manufacture technical of large length-diameter ratio composites long-tail nozzle was presented in this paper. The choice of materials, design of mould and manufacture techniques were investigated in de-tails. The carbon/carbon throat and copper sintered tungsten nozzle were wound in the middle of long-tail nozzle insulation. Compare with the traditional manufacture techniques, the integral manufacture techniques could improve the production efficiency, quality reliability and integrity and re-erosion capability.
