U型蜂窝夹芯前缘制造技术研究

为解决U型蜂窝夹芯前缘制造过程中常见的脱粘、铺层皱褶、蜂窝芯尺寸超差等技术质量问题,从调整蜂窝芯展开基准面、优化蜂窝芯热定型工艺、控制铺层滑移等角度入手、完善此类零件的制造工艺流程。经过多个典型件验证,零件表面平整,外形尺寸符合要求,内部无缺陷,研究结果给相似零件的制造提供了借鉴。

Manufacture of U Shape Honeycomb Sandwich Leading Edge

This research is aiming to resolve the technical matters such as unstick, prepreg fold and dimension devia-tion of honeycomb core in the U shape sandwich leading edges manufacture process. The choice of developed surface, the honeycomb core heat setting, the prevention of prepreg gliding are analyzed and the process is optimized. Several products are inspected carefully, the surface and the dimension are qualified. The result of this research is helpful to the manufactur-ing of similar products.
