Embodiment 1

[0035] Example 1: A solidification and molding device for composite material I-shaped reinforced wall panels

[0036] Such as figure 1 The forming device shown is a frame structure, including a skin forming panel 1, a skin forming process cover plate 5, a long stringer positioning seat 2, a long stringer upper edge strip cover plate 10, an upper edge strip cover plate support seat 3, positioning Mandrel 8 and pressure transmission mandrel 9.

[0037] Among them: the skin forming panel 1 is used for paving the carbon fiber composite skin; the panel material of the skin forming panel 1 is a composite panel or invar steel material to reduce the thermal expansion during the part forming process. The cover plate 5 of the skin forming process is a composite material structure, and the cover plate 5 of the skin forming process is provided with several long stringer limiting grooves 6 parallel to each other; the size of the long stringer limiting grooves 6 is the same as The size of...

Embodiment 2

[0041] Embodiment 2: A kind of solidification forming method of composite I-shaped reinforced wallboard

[0042] This molding method adopts the molding device described in Embodiment 1, and the main molding process flow chart is as follows Figure 5 Shown, with the following steps:

[0043] (1) First, lay a carbon fiber composite material skin on the skin forming panel 1, and reserve 10-25mm margin around the skin;

[0044] (2) Apply release agent on the side of the skin forming process cover plate 5 close to the skin and around the girder limit groove 6, and use the positioning lugs reserved on the skin forming process cover plate 5 to pass the positioning The pin is positioned with the positioning hole 4 on the skin forming panel 1, and placed on the paved skin surface to obtain a skin prefabricated body;

[0045] (3) After combining the left and right webs, upper and lower edge strips and one-way strip carbon strips of the laid long stringers, remove them from the long st...

Abstract

The invention discloses a composite material I-shaped stiffened wall plate curing molding device and a molding method. The device comprises a skin molding panel 1 used for paving and wrapping of skin,a skin molding technological cover plate 5 used for paving and wrapping of the skin, a positioning core die 8 used for I-shaped long purlin molding, a pressure transmitting core die 9 and a long purlin upper edge strip cover plate 10; the skin molding technological cover plate 5 is provided with a plurality of long purlin limiting grooves 6 in parallel, the long purlin limiting grooves 6 are matched with a long purlin lower edge strip 13 in size, an I-shaped long purlin 11 is divided by a long purlin web plate 14 located between a long purlin upper edge strip 12 and the long purlin lower edgestrip 13 and at the middle portion into two relatively-independent symmetrical C-shaped spaces, and the pressure transmitting core die 9 is arranged in one C-shaped space and is attached to the I-shaped long purlin; and the positioning core die 8 is located in the other C-shaped space and attached to the I-shaped long purlin, and the top of the long purlin upper edge strip 12 is covered with thelong purlin upper edge strip cover plate 10. The problems that in the prior art, the long purlin axis degree deviation exists, the thickness is not even, and the overall molding quality is poor are solved.

Description

technical field [0001] The invention belongs to the field of composite material technology manufacturing, and in particular relates to a solidification molding device and a molding method for a composite material I-shaped reinforced wallboard. Background technique [0002] Advanced composite materials have been widely used in the aerospace field because of their advantages such as high specific strength, specific modulus, excellent corrosion resistance, fatigue resistance and designability. Due to its good post-buckling bearing capacity and weight reduction effect, the composite material reinforced panel structure has been widely used in the main load-bearing or secondary load-bearing components of aircraft. [0003] The forming process of large-scale composite material reinforced wallboard structure mostly adopts integral forming processes such as co-gluing, secondary gluing, and co-curing. The molding methods of co-bonding and secondary bonding will increase the curing ti...
