Detailed Description
The present invention will be further described in detail with reference to the drawings and examples, which are only for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
As shown in fig. 1, the invention relates to a multi-wall type wing made of a carbon fiber composite material, which is formed by integrating carbon fiber composite materials, namely, the multi-wall type wing is designed to be formed by integrating an RTM technology, so that a plurality of connecting fasteners can be reduced, the cost and the weight can be reduced, the wing comprises a wing tip 1, a wing box section 2, at least one rib 3, a metal joint 4, a corner piece 5 and a sealing plate 6, the rib 3 is connected with the wing box section 2 through the corner piece 5, the tail edge of the wing is sealed through the sealing plate 6, and the metal joint 4 is a wing body connecting interface.
Paving and shaping the cut carbon fiber fabric on a corresponding pre-shaping mold according to the layering design, paving the shaped pre-shaping fabric on a corresponding position in an RTM mold, finishing glue injection work in a mold cavity at 50 ℃, and finally curing and integrally shaping in a curing furnace. During assembly, all parts are assembled together in a mixed connection mode of cementing and riveting, and the carbon fiber composite multi-wall wing structure can be obtained.
According to the invention, the structure of the wing box section of the carbon fiber composite material is determined through process molding evaluation and finite element analysis; the multi-wall wing layering form is determined through fiber sim analysis, a box structure is adopted by a wing box section and a wing tip, the wing is connected with a fuselage through a metal joint, ribs and the wing box section are connected through corner pieces in a glue riveting mode, and finally a sealing plate is glued. The wing box section and the wing tip are integrally formed by adopting RTM (resin transfer molding), and the RTM process has lower cost compared with the traditional autoclave process, so that a plurality of connecting fasteners can be reduced in the structural form, thereby greatly reducing the cost and the weight.
