Problems solved by technology

The rib surface is used as the molding surface, which can better control the axis of the rib, but how to design the mold, the demoulding of the T-shaped rib is relatively difficult, and at the same time, due to the flow of resin during the curing process of the composite material, it will cause Resin enrichment and partial lack of glue, there is no mature solution

Embodiment 1

[0025] Such as Figure 1-Figure 2 As shown, a composite material T-shaped reinforced wall plate autoclave forming mold structure includes a mold 1 provided with a T-shaped groove 3, and the T-shaped groove 3 is used to make a composite material T-shaped reinforced wall plate;

[0026] The T-shaped rib 6 is placed in the mold 1 with the T-shaped groove 3, and accurately positioned with the mold 1 through the positioning hole, and a sealing strip 5 is designed between the T-shaped rib 6 and the mold 1;

[0027] Sealing grooves 2 are arranged on the groove walls on both sides of the T-shaped groove 3, and sealing strips 5 are installed in the sealing grooves 2. The sealing strips 5 can prevent the resin from flowing during the curing process of the prepreg 9, resulting in local lack of resin and preventing resin from flowing in. In the groove, the difficulty of demoulding is reduced and the product quality is guaranteed;

[0028] The T-shaped ribs 6 are dry ribs, and the wet ski...

Embodiment 2

[0030] In this embodiment, a positioning hole A is provided on the T-shaped rib 6, and a positioning hole B is obtained by drilling a hole on the mold 1. The positioning hole A and the positioning hole B are used together to ensure that the T-shaped rib 6 is accurately installed on the mold 1. superior.

[0031] The T-shaped rib 6 includes a web and an edge, and the T-shaped rib 6 web is inserted into the bottom of the T-shaped groove 3 of the mold 1, and the edge is placed on the mold 1.

[0032] The positioning hole A of the T-shaped rib 6 is arranged on the flange, the number of the positioning hole A is two, and the position and quantity of the positioning hole B cooperate with the positioning hole A.

[0033] The T-shaped rib 6 is placed in the mold 1 with the T-shaped groove 3, and accurately positioned with the mold 1 through the positioning holes (including the positioning hole A and the positioning hole B) to ensure the accuracy of installation. The T-shaped groove 3...

Embodiment 3

[0035] In order to solve the problem of mass production and improve efficiency. A plurality of T-shaped grooves 3 can be arranged on the mold 1 of the present solution, and the T-shaped grooves 3 are spaced apart by a certain distance.

[0036] The T-shaped grooves 3 are arranged in one or more rows; when the T-shaped grooves 3 are arranged in multiple rows, the T-shaped grooves 3 form a groove matrix, which is used to make a reinforced wall panel with a plurality of T-shaped ribs 6 .

[0037] Mold 1 is a cylinder as a whole, and some T-shaped grooves 3 are arranged on the side wall of mold 1, and are used for making the integral composite barrel section 13 (such as Figure 9 shown).

[0038] Through this embodiment, not only can obtain single composite material T-shaped reinforced panel 11 (such as Image 6 shown) can also obtain multi-composite material T-shaped reinforced wall panels 12 (such as Figure 7 shown), and include T-stiffened panels for integral composite bar...

Abstract

The invention discloses a composite material T shaped ribbed wallboard autoclave forming die structure and a forming method. The structure comprises a die provided with a T shaped groove; the die is used for manufacturing a composite material T shaped ribbed wallboard; a T shaped rib is placed in the die provided with the T shaped groove and is precisely positioned through a positioning hole and the die; a sealing strip is arranged between the T shaped rib and the die and ensures that resin does not flow into the T shaped groove during the curing process; an oblique angle is designed on the Tshaped groove of the die to ensure demoulding feasibility; a dried rib and a wet skin are in glue joint to manufacture the T shaped ribbed wallboard; the rib for manufacturing the composite material ribbed wallboard is high in location degree and axis degree; and a rotary body structure provided with an internal T shaped ribbed structure also can be manufactured.

Description

technical field [0001] The patent of the present invention mainly belongs to the field of composite material T-shaped reinforced wall plate forming, and specifically relates to a composite material T-shaped reinforced wall plate autoclave forming mold structure and method. Background technique [0002] Due to the advantages of high specific strength, high specific stiffness and good designability of composite materials, the weight reduction of aircraft structures can be realized on a large scale. Therefore, more and more composite materials are used in aircraft structures. According to the carrying capacity and structural characteristics of the aircraft, the reinforced wall panels can be mainly divided into T-type, J-type, I-type, hat-type structures and hybrid reinforced wall panels. In order to reduce the manufacturing cost of composite material panels, the integrated design and manufacturing technology of composite materials can reduce the number of products on a large sc...
