大型复合材料壁板先进制造技术及应用

摘要

The large and integrative composite panels can not only reduce the plane weight, but also improve the plane performance, simplify assembly. Because of layup complexity in the large-sized co-cured composite part, it is dif-ficult for traditional molding technology and quality is unstable. With the theory of design for manufacture, DFM, and ap-plying the advanced digital manufacture technique to the composite part , it is a good method for solving the large-sized composite panel manufacture.%大型整体化的复合材料壁板会起到较好的减重效果,明显提升飞机的整体效能,简化装配工艺.大尺寸共固化的复合材料制件铺层结构复杂,传统成型工艺难度大,质量稳定性差,组合元件形位尺寸有偏差.随着设计制造一体化(DFM)理念的出现,先进数字化制造技术在复合材料零件制造方面的应用很好地解决了大尺寸复合材料壁板类零件制造的难题.
