An all-composite wing gluing method and all-composite wing

Abstract

The invention relates to an all-composite-material wing gluing method and an all-composite-material wing. The gluing method is as follows: firstly, a lower skin is placed on a frame made of composite materials, and the process is carried out through ear pieces and positioning holes. Positioning and fixing; then glue the front spar and rear spar to the lower skin through adhesive; then glue the wing rib to the lower skin through adhesive; finally fix the upper skin on the assembly tool Mold, and apply adhesive to the front spar, rear spar and rib of the wing, close the mold, and complete the bonding. In this way, the prepared wing can use the composite material frame as the main bearing member, laying the foundation for the airworthiness road of the domestic all-composite main bearing member civil aircraft, and compared with the traditional metal structure wing, it has tooling , the advantages of fewer parts and fasteners, and at the same time, the adhesive connection method has the advantage of uniform stress distribution, so as to achieve the purpose of reducing the weight of the structure by 30%, which can improve the quality of the product while reducing the production cost and production cycle.

Description

technical field [0001] The invention belongs to the technical field of aircraft processing, and particularly relates to an all-composite material wing gluing method and an all-composite material wing. Background technique [0002] At present, in the aircraft manufacturing industry at home and abroad, the aircraft wings use metal structures (metal frames) as the main bearing parts. The metal structures are assembled from multiple metal parts by riveting or bolt fasteners. It is heavy, there are many parts, and the production cycle is long, which leads to a significant increase in the production cost of the product and a greatly extended production cycle. SUMMARY OF THE INVENTION [0003] In order to solve the above problems existing in the prior art, the present invention provides a method to realize the application of composite materials as the main bearing member, which has the advantages of less tooling, parts, fasteners and uniform stress distribution, and reduces the w...
