Problems solved by technology

However, this kind of film cover has more layers of woven fabric, the film cover is thicker, and it is cumbersome to use, and the separation area is relatively large, which is easy to form internal defects, resulting in a decline in overall performance and difficult to control quality stability.
Therefore, there are certain limitations in the actual application of this type of launching box cover

Embodiment 1

[0024] like figure 1 As shown, a carbon fiber composite frangible cover is mainly designed and manufactured with carbon fiber cloth and epoxy resin glue as the main material for the missile launch box cover. Specifically, the multi-functional flat composite launch case cover of the present invention mainly includes: a flange surface 1, which is a circular ring, and a throwing body 3 is arranged in the middle; the weak zone 2 is located between the flange surface 1 and the throwing The middle part of the connection of the body 3 is a ring concentric with the flange surface; the throwing body 3 is a circle concentric with the flange surface and the weak area, and adopts carbon fiber layup.

[0025] like figure 2 As shown, what is shown is a sectional structure of a fragile cover made of carbon fiber composite material. The middle weak area 2 is obtained by opening a groove 4 on the overall circular flat plate. Cured and formed, the carbon fiber cloth layer is a ladder laminat...

Embodiment 2

[0027] like image 3 As shown, what is shown is a fragile cover of carbon fiber composite material, which is mainly designed and made of missile launch box cover with carbon fiber cloth and epoxy resin as the main materials. Specifically, the carbon fiber composite frangible cover of the present invention mainly includes: a flange surface 1, which is a ring with a throwing body 3 in the middle; In the middle of , there is a ring concentric with the flange surface 1, and a fixed number of cashew-shaped holes are opened in the ring part, such as Figure 4 As shown, the hole is filled with resin material; the projectile body 3 is a circle concentric with the flange surface and the weak area, and adopts carbon fiber layup.

[0028] like Figure 5 The sectional structure of a fragile cover made of carbon fiber composite material shown is the same as that of Example 1. Open cashew-shaped holes in the weak area according to a fixed size and a fixed number, and fill them with epoxy...

Embodiment 3

[0030] like image 3 As shown, a carbon fiber composite fragile cover is mainly designed and manufactured with carbon fiber cloth and epoxy resin as the main material of the missile launch box cover. Specifically, the carbon fiber composite frangible cover of the present invention mainly includes: a flange surface 1, which is a ring; A ring concentric with the flange surface, the ring is partially opened with a fixed number of cashew-shaped holes, such as Figure 4 As shown, the hole is filled with resin material; the throwing body 3, the throwing body is a circle concentric with the flange surface and the weak area, and adopts carbon fiber layup.

[0031] like Figure 5 The sectional structure of a fragile cover made of carbon fiber composite material shown is the same as that of Example 1. Open cashew-shaped holes in the weak area according to a fixed size and a fixed number, and fill them with epoxy resin. When the overall diameter of the cover is set to 300mm, the numbe...

Abstract

The invention discloses a fragile cover made of carbon fiber composite material, which belongs to the field of missile launching devices. The fragile cover of the invention is a whole, including a flange surface and a throwing body arranged in the middle of the flange surface. The throwing body There is a weak area in the connection area with the flange surface; a series of holes or grooves are opened on the weak area, and the hole or groove area is filled with resin material; the flange surface of the fragile cover and the whole of the throwing body The circular plate adopts carbon fiber layup; the present invention is a flat-plate composite launch box with simple structure, strong bearing capacity, light structure weight, good stability, airtightness, pressure bearing, cover opening and electromagnetic shielding, etc. cover.

Description

technical field [0001] The invention belongs to the field of missile launching devices, in particular to a fragile cover made of carbon fiber composite material. Background technique [0002] The missile launching box cover is an important part of the missile launching device. During the daily storage of missiles, the launch box is filled with a certain amount of inert gas to prevent the electronic components of the warhead from being corroded. The cover of the box must have good airtightness and protect the missile from damage; when the missile is launched, it must be opened quickly to ensure the normal operation of the missile. emission. Therefore, the design of the missile launch box cover is one of the important factors affecting the missile launch efficiency. The traditional mechanical launch box cover generally uses mechanical cover or blasting, and its production material is mostly metal. The mechanical opening cover is usually relatively heavy, which not only incr...
