The invention discloses a large-scale high-precision composite material reflecting antenna forming process method and a designing and manufacturing mold, multiple working procedures such as inner panel forming, outer panel forming, Nomex honeycomb shaping and reflecting antenna assembling are completed at the same time through one mold with multiple purposes, and the manufacturing cost is reduced. The forming quality and the size precision of the inner panel and the outer panel are ensured through the layering process design; the position precision and the connection strength of the embedded part are ensured through the laying and positioning process of the reinforcing rib embedded part; through a reasonable PMI foam treatment process, the forming and mounting problems of the reinforcing ribs are ensured; by strictly controlling the weight in each process link, the final weight requirement of the product is ensured. 本发明公开了一种大型高精度复合材料反射天线成型工艺方法，设计及制造模具，通过一模多用同时完成内面板成型、外面板成型、Nomex蜂窝定型及反射天线组装等多项工序，降低了制造成本；通过铺层工艺
