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
The present invention 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 Ke Gong army that not only radar detection had been had to stealthy effect but also can anti-electromagnetic radiation have disturbed to use.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, a kind of wallboard of shelter with radar invisible band electromagnetic shielding is provided.
Technical problem solved by the invention 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 during shelter with the inside panel of the similar wallboard of other 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 present invention makes can have stealthy effect to radar detection, can have shielding action to electromagnetic wave again,
Other relevant criterion that also meets shelter.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of wallboard of shelter of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention 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, by three-decker, absorb the radar wave that sees through exterior skin 1, strengthened stealth effect.
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 during shelter with the inside panel of the similar wallboard of other 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 5 pairs of radar wave reflections of skeleton.
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.
