Problems solved by technology

[0002] The wall panels of traditional shelters are generally made of aluminum alloy plates as inner and outer panels and polyurethane foam sandwiches. The wall panels have no stealth effect on radar detection; the wall panels may not be able to shield electromagnetic radiation; or only Made of a layer of wave-absorbing material, the stealth effect is not obvious, and radar stealth and electromagnetic shielding have always been a pair of contradictions. There is no shelter that can not only stealth radar detection but also prevent electromagnetic radiation interference for troops to use.

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to figure 1 , a shelter panel with radar stealth and electromagnetic shielding, which sequentially includes an outer skin 1, a wave-absorbing sandwich layer 2, a thermal insulation material layer 4, and an inner skin 7 from outside to inside, and the layer between the outer skin 1 and the inner skin 7 There is a skeleton 5 in between, and the wave-absorbing sandwich layer 2 has three layers, the first layer is the honeycomb bottom layer, the second layer is the middle layer made of chopped carbon fiber and carbon fiber fabric mixed prepreg that absorbs radar waves, and the third layer is the ring The surface layer made of oxygen resin, the three-layer structure of the wave-absorbing sandwich layer 2 is formed by lamination, and the radar wave passing through the outer skin 1 is absorbed through the three-layer structure, ...

Abstract

A shelter wallboard with radar stealth and electromagnetic shielding functions. The shelter wallboard sequentially comprises an outer mask, wave absorbing sandwich layers, a heat preservation material layer and an inner mask from the outside to the inside, and frames are arranged between the outer mask and the inner mask. The shelter wallboard is characterized in that the wave absorbing sandwich layers include three layers, a first layer is a honeycomb bottom layer, a second layer is a middle layer made of mixture preimpregnation materials of short carbon fiber and carbon fiber fabric, and a third layer is a surface layer made of epoxy resin. The shelter wallboard has a good stealth effect on radar detection, can shield electromagnetic wave inside and outside of a shelter and is also in accordance with other relevant standards of the shelter.

Description

technical field [0001] The invention relates to the technical field of shelters, in particular to a shelter wall plate with radar stealth and electromagnetic shielding. Background technique [0002] The wall panels of traditional shelters are generally made of aluminum alloy plates as inner and outer panels and polyurethane foam sandwiches. The wall panels have no stealth effect on radar detection; the wall panels may not be able to shield electromagnetic radiation; or only Made of a layer of wave-absorbing material, the stealth effect is not obvious, and radar stealth and electromagnetic shielding have always been a pair of contradictions. There is no shelter that can not only stealth radar detection but also prevent electromagnetic radiation interference for troops to use. . Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a shelter wall with radar stealth and electromagn...
