Abstract
A square bin wall plate with radar stealth and electromagnetic shielding functions sequentially comprises outer skin, wave-absorbing sandwich layers, a heat preservation material layer and inner skin from outside to inside, wherein a framework is arranged between the outer skin and the inner skin. The square bin wall plate is characterized in that the number of wave-absorbing sandwich layers is three, the first layer is a honeycomb bottom layer, the second layer is an intermediate layer made of short carbon fibers absorbing radar waves and carbon fiber fabric mixed prepreg, and the third layer is a surface layer made of epoxy resin. The square bin wall plate has a high stealth effect of radar detection, can shield electromagnetic wave radiation inside and outside a square bin and can conform to other relevant standards of the square bin.
Description
Technical field
The utility model relates to shelter technology field, particularly a kind of wallboard of shelter with radar invisible band electromagnetic shielding.
Background technology
Its wallboard of tradition shelter is generally composited as inside and outside illiteracy plate and polyurethane foam sandwich by aluminium alloy plate, and its wallboard does not have stealthy effect to radar detection; Its wallboard also differs and shields surely electromagenetic wave radiation; Or only make with one deck absorbing material, stealth effect is not obvious, and radar invisible and electromagnetic shielding be always conflict, still do not have a kind of shelter that not only radar detection had been had to stealthy effect but also can anti-electromagnetic radiation disturb can be for army.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of wallboard of shelter with radar invisible band electromagnetic shielding is provided.
The technical problem that the utility model solves is achieved through the following technical solutions:
A kind of wallboard of shelter with radar invisible band electromagnetic shielding, described wallboard of shelter comprises successively from outside to inside exterior skin, inhales ripple sandwich of layers, adiabator layer and inside panel, between described exterior skin and inside panel, be provided with skeleton, described suction ripple sandwich of layers has three layers, ground floor is honeycomb bottom, the second layer is the intermediate layer that the chopped carbon fiber of absorbing radar wave is made with carbon fibre fabric mixing prepreg, the 3rd layer of superficial layer of making for epoxy resin, absorbs the radar wave that sees through exterior skin by three-decker.
Further, the three-decker of described suction ripple sandwich of layers is by laminated into type.
Preferably, described exterior skin is by epoxy resin and aramid fiber is compound forms, and has certain mechanical strength and radar wave is had to good wave.
Preferably, the resin content of described epoxy resin is lower than 20wt%.
Preferably, described adiabator layer is low-density polyurethane rigid foam plate, and density is 0.05g/cm
3, play thermal insulation function.
Further, between described skeleton and inside panel, be provided with insulation bridge.
Preferably, described inside panel is the single layer alloy aluminium sheet of thickness 0.8mm, can combination when shelter with the inside panel of the similar wallboard of other the each wall formation electro-magnetic screen layer that is connected to each other.
Preferably, on the faying face that described skeleton contacts with exterior skin, scribble glass fibre antiradar coatings, to block skeleton to radar wave reflection.
The shelter that the utility model is made can have stealthy effect to radar detection, can have shielding to electromagnetic wave again
Act on, also meet other relevant criterion of shelter.
Brief description of the drawings
Fig. 1 is the partial sectional view of the utility model wallboard of shelter.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, a kind of wallboard of shelter with radar invisible band electromagnetic shielding, comprise successively from outside to inside exterior skin 1, inhale ripple sandwich of layers 2, adiabator layer 4 and inside panel 7, between exterior skin 1 and inside panel 7, be provided with skeleton 5, inhale ripple sandwich of layers 2 and have three layers, ground floor is honeycomb bottom, the second layer is the intermediate layer that the chopped carbon fiber of absorbing radar wave is made with carbon fibre fabric mixing prepreg, the 3rd layer of superficial layer of making for epoxy resin, inhale the three-decker of ripple sandwich of layers 2 by laminated into type, absorb the radar wave that sees through exterior skin by three-decker, strengthen stealth effect.
Exterior skin 1 is by epoxy resin and aramid fiber is compound forms, and wherein the resin content of epoxy resin, lower than 20wt%, has certain mechanical strength and radar wave is had to good wave.
Adiabator layer 4 is low-density polyurethane rigid foam plate, and density is 0.05g/cm
3, play thermal insulation function, cut off convection current and the radiation of the inside and outside heat energy of shelter.
Between skeleton 5 and inside panel 7, being provided with insulation bridge 6, adopting heat-insulating material, is the heat transfer pathway of skeleton 5 and Inner Mongol plate 7.
Inside panel 7 is the single layer alloy aluminium sheet of thickness 0.8mm, can combination when shelter with the inside panel of the similar wallboard of other the each wall formation electro-magnetic screen layer that is connected to each other.
On the faying face that skeleton 5 contacts with exterior skin 1, scribble glass fibre antiradar coatings 3, to block skeleton 5 to radar wave reflection.
Wallboard by the compound composition of above-mentioned material can have stealthy effect to radar detection, can have electromagnetic shielding action to electromagnetic wave again, also meets other relevant criterion of shelter.
