Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] The forming tooling used for the foam sandwich composite structure winglet is composed of an upper forming die 1 and a lower forming die 2, the upper forming die 1 is a resin-based composite material mold, and the lower surface of the mold is connected with the foam sandwich composite material structural winglet. The profiles on the tiplets are the same. The upper molding die 1 is laid up and formed on the upper molding die stacking die 13 . The lower forming die 2 is a composite material frame die, which is composed of a longitudinal partition 5, a transverse partition 6, a bottom plate of the lower forming die frame 12 and a forming panel 3 of the lower forming die. During the manufacturing process of the lower forming die 2, the 8mm thick glass The fiber board is processed by numerical control, and the lower forming mold transverse partition 5, the lower f...
