Embodiment Construction

[0029] In order to make the object, technical solution and effect of the present invention clearer and clearer, the following examples are given to further describe the present invention in detail. It should be pointed out that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, a frangible cover of electromagnetic shielding interlayer composite material of the present invention is mainly designed and manufactured with carbon fiber cloth, conductive metal film, polyurethane foam and epoxy resin glue as the main materials for the missile launch case cover. Specifically, the electromagnetic shielding interlayer composite frangible cover of the present invention includes: a flange 1 and a throwing body 3 , and the junction of the flange 1 and the throwing body 3 is called a separation area 2 . Projectile body 3 sandwich structure such as figure 2 As shown, the projec...

Abstract

The invention discloses an electromagnetic shielding interlayer composite material fragile cover and a preparation method thereof, and belongs to the technical field of missile launching devices. Theelectromagnetic shielding interlayer composite material fragile cover comprises a flange and a throwing body, and the joint of the flange and the throwing body is called as a separation area; the throwing body is made of an electromagnetic shielding interlayer composite material, and is formed by curing and molding a foam interlayer, a metal conductive film and carbon fiber cloth by taking epoxy resin glue as a matrix; the edge of the throwing body is provided with a circle of non-penetrating V-shaped chamfer, and the V-shaped chamfer is filled with the epoxy resin glue, and then is glued withthe edge of the flange to form the separation area. The electromagnetic shielding interlayer composite material fragile cover is simple in structure, high in bearing capacity, light in structural weight and good in stability, and has multiple functions of electromagnetic shielding and the like.

Description

technical field [0001] The invention belongs to the technical field of missile launching devices, and in particular relates to an electromagnetic shielding interlayer composite frangible cover and a preparation method thereof. Background technique [0002] The design of the missile launching box cover is one of the important factors affecting the rapid response ability of the missile. Therefore, when developing the missile storage launching box, the design of the box cover is very important. The box cover is mainly able to withstand a certain pressure difference, has good sealing performance, and can be opened quickly when launching a missile. In order to meet the above requirements, the cover of the missile launching box used to use a mechanical cover, an explosive bolt opening cover, etc. (see US Pat. If the mechanical opening cover needs to be opened by a hydraulic system, the mechanism is complicated, which not only increases the weight of the launch box and delays tim...
