[0017] The present invention will be described in detail below with reference to the accompanying drawings.
[0018] The molding tool used for the winglet of the foam sandwich composite structure is composed of an upper molding die 1 and a lower molding die 2. The upper molding die 1 is a resin-based composite material mold, and the lower profile of the mold is connected to the foam sandwich composite structure wing. The upper profile of the tiplet is the same. The upper molding die 1 performs stack molding on the upper molding die stacking die 13 . The lower molding die 2 is a composite material frame mold, which is composed of a longitudinal partition 5, a transverse partition 6, a lower molding die frame bottom plate 12 and a lower molding die molding panel 3. During the manufacturing process of the lower molding die 2, the 8mm thick glass The fiber board is processed by numerical control, and the lower molding die transverse partition 5, the lower molding longitudinal par...
