To further reduce costs and lighten the structural mass of forming equipment for facilitating process forming， the aluminum alloy grid mold was combined with the flat-cast silicone rubber grid mold and upgraded to a three-dimensional cast silicone rubber grid mold for the conical composite oblique grid structure， which enables low-cost automated winding forming while meeting winding precision requirements. The fiber tow winding trajectories for double-head closure of the geodesic spiral rib composite grid structure with two pieces opposite to the large end via elliptical geodesic transition were calculated with high precision， thereby making the automated continuous winding smoother and more stable， as well as saving materials and improving production efficiency. High-efficiency automatic continuous cyclic winding was realized， and a braided effect was achieved at the nodes. Flat silicone rubber grid strips for resin absorption and compaction were prepared to further improve the structural quality of the ribs and nodes. The formed structural components have passed various tests and can be applied in practical engineering.
