Embodiment Construction

[0029] see Figure 1-7 As shown, a co-curing molding device for T-shaped reinforced wall panels of composite materials, its structure includes a long stringer forming die set 1, a preforming die set 2, a positioning combination device 13, a skin forming die 14, and a stringer forming die set 1 Including a number of different truss forming dies. The truss forming die is a door-shaped structure made of composite materials. There are L-shaped grooves at the two top corners respectively. The shape and size of the grooves are consistent with the T-shaped stringer products. There is an inverted U-shaped positioning gap in the middle of the bottom of the two sides of the stringer forming mold. The preforming mold set 2 includes a plurality of preforming molds corresponding to the truss forming molds, the truss forming mold set 1 and the corresponding preforming mold set 2 are combined into one body through the positioning combination device 13, and are positioned and fixed on the ski...

Abstract

The invention provides a co-curing forming device for a composite T-shaped stiffened wallboard and a using method. According to the method, a plurality of combined molds with wet-state L-shaped stringers are positioned, combined, fixed and clamped through a stringer forming mold set, a pre-forming mold set and a positioning and combining device, so that two adjacent wet-state composite L-shaped stringers form one wet-state composite T-shaped stringer; and the plurality of wet-state composite T-shaped stringers and wet-state composite skin are in accurate butt joint through accurate butt joint of the positioning and combining device and a skin forming mold, the wet-state composite T-shaped stiffened wallboard is formed, a co-curing process is conducted on the wet-state composite T-shaped stiffened wallboard through an autoclave, and finally co-curing forming of the composite T-shaped stiffened wallboard is achieved.

Description

technical field [0001] The application relates to the technical field of composite material wallboard manufacturing, in particular to a composite T-shaped reinforced wallboard co-curing molding device and its use method. Background technique [0002] Due to the advantages of high specific strength, high specific stiffness, and designable performance, composite materials are widely used in various military aircraft and civil aircraft. Most of the wing panels, fuselage panels, flat tail panels, and vertical tail panels of the aircraft are T-shaped reinforced panels, which are composed of T-shaped stringers and skins. Co-cementation and co-curing are mainly used in the manufacture of composite T-shaped reinforced wall panels. Among them, co-cementation is to cure and form the wet-state composite T-shaped stringer and the wet-state composite skin separately, and then carry out precise butt coating. Glue cementation, and then perform secondary curing to form a composite T-shaped...
