Composite material wing integral molding technological method and composite material wing integral molding tool

Abstract

The invention discloses a composite material wing integral molding technology method and a composite material wing integral molding tool. A metal female mold and a silicon rubber male mold are assisted in molding. The composite material wing integral molding technology method comprises the following steps: firstly, manufacturing the female mold, and manufacturing a male mold by utilizing the female mold; cleaning a demolding agent sprayed on the upper and lower molded surfaces of the female mold; paving upper and lower wing panels of the composite material wing respectively on the upper and lower molded surfaces of the female mold; arranging the male mold and the wing front edge part on the lower wing panel of the wing; folding the upper mold and the lower mold of the female mold; putting the folded female mold and male mold and a composite material wing product into a hot pressing tank, and curing; demolding after curing, and trimming to obtain the composite material wing. Therefore, the composite material wing with relatively small size is molded integrally, the integral weight of the composite material wing is reduced, and the structure intensity of the composite material wing is improved. The integrally molded composite material wing is good in interior quality, the size of the external wing type molded surface is accurate, meanwhile the thickness of a paving layer of the composite material wing product can be strictly controlled, and the integral molding quality of the composite material wing is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of aviation manufacturing process equipment, and in particular relates to a composite material wing integral molding process method and tooling, which are suitable for the integral molding of smaller-sized composite material wings. Background technique [0002] Composite materials have strong designability, light weight, high specific strength, corrosion resistance and unique electromagnetic penetration performance, making them widely used in structural components of aviation products. Among them, the aircraft wing is one of the earliest components to adopt composite material structure. The traditional composite material structure wing adopts the upper and lower skins to be formed separately, and then the upper and lower skins are combined by assembly tooling, and then glued to the skeleton to complete the manufacture of the composite material wing. The manufacturing process of this method is complicated, a...
