摘　　要：介绍了一种用连续变形带来斜缠制造防热层的新技术。通过对工艺和材料性能等多方面的对比试验 ,结果表明用连续变形带材料 ,斜缠防热层的制造工艺性得到了很大的改善 ,缠绕件较为密实 ,布层排列非常规整 ,防热层表面无布层扭曲和皱折等缺陷 ,非常有利于控制防热层的滚转特性 ,而且材料的力学等性能也有很大程度的提高。由于连续变形带本身具有很强的可设计性 ,因此本技术有着很大的发展潜力和应用前景。A new method of tilt winding cone heatshield by continuous deformation tape is introduced in this paper. By evaluating properties of the processing and materials , this technology has shown a good manufacture feasibility,which gives dense winding parts and trim tape orientation, eliminates distortion and wrinkle of surface tapes,easily controls roll property of the heatshield cone, and improves mechanical properties as a result. Due to the tape is capable of being designed , this technique has good development potentialities.
