Composite material multi-beam box section co-solidifying forming technique

Abstract

The invention belongs to the technical field of composite material hot pressing pot forming techniques and particularly relates to a composite material multi-beam box section co-solidifying forming technique. The composite material multi-beam box section co-solidifying forming technique comprises the following steps of beam mold assembly manufacturing, beam blank manufacturing, beam mold assembly and beam blank assembling, outer panel skin mold assembly and outer panel skin blank manufacturing and assembling of a beam mold assembly and a beam blank as well as an outer panel skin mold assembly and an outer panel skin blank. According to the forming technique, on the basis of an existing technique of multi-time solidifying and then assembling, one-time co-solidifying forming is achieved, and the forming quality can be ensured. The composite material multi-beam box section co-solidifying forming technique has the beneficial effects that accurate positioning of an upper wall plate forming mold and a lower wall plate forming mold are achieved, and the parallelism degrees and the box section heights of the upper wall plate forming mold and the lower wall plate forming mold are ensured; accurate positioning of beam plate parts in the assembling and solidifying processes can further be ensured, so that the thicknesses and axis degrees of the parts are ensured; and the technique is easy to operate, the manufacturing period is shortened, manufacturing cost is reduced, and the weight reducing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of composite material autoclave molding technology, and in particular relates to a composite material multi-beam box section co-curing molding technology. Background technique [0002] Autoclave (Hot Air Autoelave or Atitoelave for short) is a process equipment for the characteristics of polymer-based composite molding process. The method of using this equipment for molding process is called autoclave forming method. The autoclave forming method is the main method for manufacturing continuous fiber reinforced thermosetting composite parts. It is widely used in the molding of advanced composite structures, honeycomb sandwich structures and metal or composite bonded structures. When the material is formed, it is solidified by using the uniform temperature and uniform pressure provided in the autoclave, so it can obtain composite material parts with high surface and internal quality, complex shape and large are...
