Problems solved by technology
[0003] Various types of pipes are densely distributed in the aircraft structure. The pipe structure integrally formed with composite materials can greatly reduce the scattering of radar waves, and can well meet the requirements of stealth and light weight of the aircraft structure. Among them, the functional pipes in the aircraft structure are mostly complex. The shape, curvature, and the outer surface is densely covered with vertical and horizontal ribs. It is a vertically and horizontally reinforced pipe. According to the existing technology, it is integrally formed with composite materials. The forming process is complicated, and the forming accuracy is difficult to guarantee. Defective products

The invention belongs to the technical field of composite material reinforced pipeline forming method design, and particularly relates to an integral forming method for a composite material reinforcedpipeline. The method comprises the steps that a male die is manufactured according to the inner profile of the pipeline; pipeline skins are laid on the male die layer by layer; longitudinal ribs arelaid and attached to the outer surface of the pipeline skin at the outermost side of the male die, and the male die is put into an autoclave to be cured; transverse ribs are laid and attached to the outer surface of the pipeline skin at the outermost side of the male die, and the male die is put into the autoclave to be cured; and the male die is removed.
Description
technical field [0001] The application belongs to the technical field of forming method design of composite material reinforced pipeline, and in particular relates to an integrated forming method of composite material reinforced pipeline. Background technique [0002] Composite materials have the advantages of light weight, corrosion resistance, high reliability, and the ability to reduce radar wave scattering, which can well meet the stealth and lightweight manufacturing requirements of current aircraft structures, and are increasingly used in aircraft Fabrication of structures. [0003] Various types of pipes are densely distributed in the aircraft structure. The pipe structure integrally formed with composite materials can greatly reduce the scattering of radar waves, and can well meet the requirements of stealth and light weight of the aircraft structure. Among them, the functional pipes in the aircraft structure are mostly complex. The shape, curvature, and the outer s...
