Abstract
A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive, fluid-permeable planar core layer defined between generally parallel first and second surfaces and a first face sheet laminated to the first surface of the core layer with rigidity properties superior to the rigidity properties of the core layer. The thickness of the first face sheet is substantially less than the thickness of the core layer. The core layer is made of metallic foam or a metal coating on an electrically-nonconductive, porous, nonmetallic substrate chosen from among nonwoven fibrous matting, paper, and open-cell nonmetallic foam. Also, the core layer may also may be made up of liberated branching metal nanostrands or a plurality of electrically-coupled, electrically-conductive particles, each taking the from of an electrically-nonconductive, nonmetallic substrate with a metal coating. The first face sheet includes a cured layer of resin and, distributed throughout the resin, electrically-conductive elements selected from among liberated branched metal nanostrands, metal wires, and metal meshes, in addition to fibers, woven fabric, nonwoven matting, or paper that are metal-coated.
