    • 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.

    • A highly conductive fiber reinforced tubular antenna is composed of metal coated reinforcing fibers in a composite structure. The conductive fibers may be disposed in a tubular or cylindrical fashion unidirectionally parallel to or at an angle to the axis of the tube or cylinder, thus providing multifunctional properties of strength and conductivity. Alternatively, the conductive fibers may be non-woven in configuration and disposed on one or more wrapped layers to form the antenna. The fiber reinforced composites disclosed are both lighter and stronger than their metal counterparts, while the highly increased conductive surface area in the composite creates enhanced electrical or electromagnetic performance than tubular or cylindrical antennas made of metal or nonmetal composite structures.
    • 高导电性纤维增强管状天线由复合结构的金属涂层增强纤维组成。 导电纤维可以以与管或圆柱体的轴线平行或成一定角度的管状或圆柱形方式设置,从而提供强度和导电性的多功能特性。 或者,导电纤维可以是非织造的并且设置在一个或多个包裹层上以形成天线。 所公开的纤维增强复合材料比其金属对应物更轻和更强,而与金属或非金属复合结构制成的管状或圆柱形天线相比,复合材料中高度增加的导电表面积产生增强的电或电磁性能。
