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 panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. Alternatively, a panel for a broadband electromagnetic shield includes a composite fiber-reinforced core having opposed surfaces and a layered electrically-conductive composite cover disposed on a surface of the core. The cover includes a first stratum of porous metal exhibiting pronounced low-frequency electromagnetic shielding properties and a second stratum of electrically-conductive elements exhibiting pronounced high-frequency electromagnetic shielding properties secured in an overlapping electrically-continuous relationship to the first stratum, the first stratum being a metallic lattice, and the electrically-conductive elements being a non-woven veil of electrically-nonconductive metal-coated fibers.

A composite article for incorporation at the surface of an assembly, the composite article being capable of withstanding a lightning strike by dissipating the energy of the lightning strike and by shielding the assembly from electromagnetic energy associated with the lightning strike. The composite article has a base structure made of a material exhibiting electrical conductivity that is inadequate to dissipate lightning strike energy and also inadequate to shield the assembly from the associated electromagnetic energy. Against the outer face of the base structure an electrically-conductive lightning shield is secured. The lightning shield has a substantially uniformly-distributed embedment of electrically-conductive nanostrands in a matrix that otherwise exhibits electrical conductivity that is inadequate to dissipate lightning strike energy and inadequate to shield the assembly from associated electromagnetic energy. Alternatively, an electrically-conductive ground plane may be secured against the outer face of the base structure.

ABSTRACT: A method of fabricating highly conductive and shielding electrical conduit and associated fittings is proposed. The technology will be based upon creating conductive composite tubes and fittings. Such composites have proven their ability to shield as well as their aluminum counterparts at about 1/3 the weight. Both rigid and flexible versions will be developed. Cables will be secured and tested in the new conduits. BENEFIT: Will result in very lightweight composite conduit for HPM shielding. Weight savings of 50% to 75% over current technologies.

ABSTRACT: Traditional shielding enclosures are fabricated from heavy metallic materials. Polymer and composite systems have been used extensively in enclosures for due to their significant weight and manufacturing advantages, but have not been able to provide adequate levels of electromagnetic shielding. Conductive composite materials will be used to fabricate and test composite enclosures that provide the weight and manufacturing advantages of polymer based systems while also providing required levels of electromagnetic shielding. The proposed conductive composite material systems have been proven in fabricating composites by standard manufacturing processes that match the shielding effectiveness of metallic structures, at less than half the weight. The proposed solution is affordable, corrosion immune, and transitionable to the field and also to similar platforms/applications. All proposed components are available from commercial domestic sources. An enclosure that is approximately 12x24x6 inches in size will be fabricated, tested for electromagnetic shielding effectiveness, and delivered. BENEFIT: Lightweight conductive composite cases can provide 50-75% weight savings over metallic cases while still meeting shielding requirements.

ABSTRACT: Conductive Composites has developed lightweight materials that provide high levels of conductivity and electromagnetic (EM) shielding for composite and advanced polymer materials systems. Conductive materials include metal coated carbon fibers and nonwovens, along with nickel nanostrands. The performance capabilities of the materials have now been extended and tested to include broadband frequency capabilities and protection in high-altitude electromagnetic pulse (HEMP) environments. The proposed work shall build on the successes of the Phase I effort and continue in developing lightweight composites structures for broadband electromagnetic hardening. These next steps will include investigating the format and mass fraction of each shielding constituent in a composite, alternative composite fabrication processes, and the ability to custom fit the construction of the composite to meet specific shielding requirements. New constituent materials are proposed to improve shielding performance for high energy particles. Furthermore, Conductive Composites will work closely with suppliers and the Air Force Intellectual Property Office to ensure that the technology is adequately defined, licensed, and protected. Composite panels and tubes will be fabricated, tested for electromagnetic shielding, and delivered to AFRL/AFIT for further testing. BENEFIT: Lightweight broadband shielding conductive composite systems can replace heavy metallic structures while still providing electromagnetic shielding. Weight savings can be as much as 75%. The ability to fabricate composites structures that meet the shielding requirements of demanding environments enables a new field for manufacturing lightweight shielded structures.
