Problems solved by technology

This will cause a large number of parts to be manufactured separately and then assembled. The assembly process is mostly glued and riveted. The process is complicated, the manufacturing time is long, and it requires a huge workload, which directly results in high production costs.
For UAVs that need to achieve low-cost manufacturing, the above-mentioned manufacturing methods cannot meet the needs of low-cost manufacturing

Abstract

The invention proposes an integrated mold for forming and assembling a composite wing. The integrated mold for forming and assembling includes an airfoil surface mold, a root clamp, an end clamp, a leading edge pressing plate, a trailing edge forming pressing plate, a rib positioning pressing plate, and a main spar Stoppers and rib retaining rods. The invention realizes the integration of assembly and curing of all components, and can also realize the manufacture of the rear edge during assembly, and a set of molds completes assembly, preparation of the rear edge and co-curing.

Description

technical field [0001] The invention relates to an integrated mold for forming and assembling a composite material wing, belonging to the technical field of mold manufacturing. Background technique [0002] Due to its higher specific strength and specific modulus than metal materials, composite structures have been used more and more in the aerospace field. From military aircraft to civil aircraft, composite materials have been successfully used, especially the wing as the main load-bearing component, which requires higher strength and stiffness to ensure the performance requirements and safety requirements during flight, so carbon fiber composite materials become the wing The main material of the structure. [0003] When composite materials are used as structural materials, internal defects of the materials must be avoided as much as possible, including lack of glue, voids, delamination, etc. Therefore, in order to ensure product quality, the commonly used manufacturing pr...
