Embodiment Construction

[0029] see Figure 1-7 As shown, a composite material T-shaped reinforced wall plate co-curing molding device, its structure includes a long stringer forming mold group 1, a pre-forming mold group 2, a positioning assembly device 13, a skin forming mold 14, and a long stringer forming mold group. 1. It includes a number of different truss forming dies. The truss forming die is a door-shaped structure made of composite materials. The upper surface profile is consistent with the profile at the corresponding position of the inner profile of the skin. At the top of the door-shaped structure There are L-shaped grooves at the two top corners respectively. The groove profile and size are the same as the T-shaped truss products. There are inverted U-shaped positioning gaps in the middle of the bottom of both sides of the truss forming mold. 2. It includes a plurality of pre-formed molds corresponding to the long-string forming molds. The long-string forming mold group 1 and the corres...

Abstract

The invention provides a co-curing molding device and a using method of a composite material T-shaped reinforced wall plate. The method locates, combines, fixes and clamps a plurality of combined molds with L-shaped long stringers in a wet state through a long stringer forming mold group, a pre-forming mold group, and a positioning combined device, so as to realize the realization of two adjacent wet state composite materials. The L-shaped truss forms a T-shaped truss of the wet state composite material; through the precise docking of the positioning combination device and the skin forming mold, the precise butt joint of multiple T-shaped trusses of the wet state composite material and the wet state composite material skin is realized to form The wet state composite T-shaped reinforced wall panel is subjected to a co-curing process through an autoclave, and finally the composite T-shaped reinforced wall panel is co-cured and formed.

Description

technical field [0001] The present application relates to the technical field of composite material wall panel manufacturing, in particular to a co-curing molding device for composite material T-shaped reinforced wall panels and a method for using the same. Background technique [0002] Due to its high specific strength, high specific stiffness, and designable performance, composite materials are widely used in various military aircraft and civil aircraft. The wing panels, fuselage panels, flat tail panels, and vertical tail panels of the aircraft are mostly T-shaped reinforced panels, which are composed of T-shaped trusses and skins. Co-bonding and co-curing are mainly used in the manufacture of composite T-shaped reinforced wall panels. Co-bonding is to carry out precise butt coating after curing and forming the wet composite T-shaped girders and wet composite skins respectively. Glue and cement, and then perform secondary curing to form composite T-shaped reinforced wall...
