Abstract
The invention discloses a composite material plate integrating electromagnetic shielding and wave absorption and relates to the technical field of square cabin composite material outer mask. The composite material plate comprises an upper layer, a middle layer and a lower layer. The upper layer is made of a wave-transparent composite material, the middle layer is a wave-absorbing carbon fiber fabric, and the lower layer is a metal material plate having continuous electrical conductivity.
Description
Technical field
The present invention relates to shelter composite external covering board technical field, particularly a kind of electromagnetic shielding and inhale the composite panel that ripple integrally combines.
Background technology
External covering board or the metallic plate of tradition wallboard of shelter, or nonmetallic composite plate.Metallic plate is conducive to realize electromagnetic shielding, but easily reflects the electromagnetic wave of incident; The not direct reflection electromagnetic wave of nonmetallic composite plate, but can not realize electromagnetic shielding; Yet there are no implementation structure radar invisible and electromagnetic shielding simultaneously, and be suitable as the composite panel of the external covering board of wallboard of shelter.
Summary of the invention
The composite panel that the object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of electromagnetic shielding and suction ripple to integrally combine, the external covering board by this composite panel as wallboard of shelter can be realized shelter radar invisible and electro-magnetic screen function simultaneously.
Technical scheme of the present invention is: the composite panel that a kind of electromagnetic shielding and suction ripple integrally combine, comprise upper strata, intermediate layer and lower floor, described upper strata is wave-penetrating composite material, and described intermediate layer is radar absorbing carbon fiber cloth, and described lower floor is the sheet of metallic material with continuous conduction.
Further, described wave-penetrating composite material is Penetrating.
Further, the number of plies of described radar absorbing carbon fiber cloth is arbitrary numeral in 1-20.
Further, the resin matrix of described Penetrating is epoxy resin or polyflon, and the fortifying fibre of described Penetrating is glass fibre or superhigh molecular weight polyethylene fibers.
Further, described sheet of metallic material is pure aluminum plate or alloy aluminium sheet.
The present invention compared with prior art has following features: composite panel of the present invention adds with Penetrating upper strata the structure radar invisible function that shelter is come together to realize in radar absorbing carbon fiber cloth intermediate layer, and by sheet of metallic material, lower floor realizes electro-magnetic screen function; Penetrating upper strata and radar absorbing carbon fiber cloth intermediate layer be implementation structure radar invisible function not only, also can strengthen the electro-magnetic screen function of composite panel of the present invention simultaneously, make as the shelter of wallboard of shelter external covering board, than the shelter of making external covering board of metallic plate, to there is higher electromagnetic shielding grade with composite panel of the present invention.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
