Embodiment

[0017] A composite material panel with electromagnetic shielding function, comprising at least three layers of composite material layers 1, 2, 3 and at least two layers of wire mesh layer 4, the wire mesh layer 4 includes at least one layer of 120 mesh to 200 mesh As for the wire mesh, at least one layer of composite material is arranged between adjacent wire mesh layers 4 , and the outermost layer and the innermost layer of the panel are composite material layers 1 and 3 .

[0018] This kind of composite material panel with electromagnetic shielding function uses carbon fiber composite material and wire mesh to combine to achieve the composite plate material with electromagnetic shielding effect. The composite material panel is light in weight, is not easy to be debonded with foam, honeycomb, etc., and has an electromagnetic shielding effect greater than 40dB in the range of 100kHz-10GHz. The deck is easy to install, and the wire mesh connection is convenient and reliable.

Abstract

The invention provides a composite material panel with the electromagnetic shielding function.The composite material panel comprises at least three composite material layers and at least two metal wire mesh layers.The metal wire mesh layers include at least one 120-200-mesh metal wire mesh layer.At least one composite material layer is arranged between every adjacent metal wire mesh layers.The outmost layer and the innermost layer of the panel are the composite material layers.The composite material panel with the electromagnetic shielding function has the electromagnetic shielding function, is low in weight and is not likely to be debonded with foams or honeycombs or the like, and the electromagnetic shielding effectiveness within the range from 100 kHz to 10 GHz is larger than 40 dB.A deck is easy to install, and metal wire meshes are convenient and reliable to connect.

Description

technical field [0001] The invention relates to a composite material panel with electromagnetic shielding function. Background technique [0002] The electromagnetic shielding shelter is a vehicle-mounted shelter similar to a vehicle-mounted container. The electronic shielding shelter is generally composed of six decks. At present, the deck is generally a sandwich structure of aluminum alloy skin. The electronic shielding shelter is used for Electronic equipment and microelectronic equipment are installed in the cabin. In order to ensure the reliable operation of the electronic equipment and microelectronic equipment in the cabin, the cabin body of the shelter must have certain electromagnetic shielding performance against the electromagnetic environment. The cabin combined with aluminum alloy cabin panels has a large self-weight and a large heat transfer coefficient, and panel degumming is prone to occur during field use, and when the temperature changes sharply, there will...
