AbstractNanoSonicâ€™s breakthrough technology of Metal RubberTM lends itself to the Armyâ€™s objective of reducing the EMI susceptibility of wiring on advanced helicopters, by 1) improving the performance of current technology wiring harnesses, and 2) using Metal Rubberâ€™s unique characteristics to fundamentally change wire harness design. Metal Rubber offers significant weight reduction over current solid metal wire, RF shielding and electrical grounding materials. Metal Rubber is a self-assembled nanocomposite with an electrical conductivity on the order of that of bulk copper (107 S/m). Its mass density (1 g/cc) is less than that of copper (8.96 g/cc), so replacing copper wiring with Metal Rubber may result in weight savings of up to 90%. Metal Rubber also exhibits broadband EMI shielding behavior for low areal densities, so may be used as lightweight shielding/ground sheath within cable to reduce EMI coupling and improve EMC performance, and as electrically conducting coating or appliquÃ© on composite structure. During Phase I, NanoSonic will fabricate shielded Metal Rubber wire and cable and versions of shielding/ground materials, and evaluate their electromagnetic and environmental performance according to MIL SPEC standards. NanoSonic has a CAI of 40, works with multiple major defense contractors and has specialized materials onboard fielded defense platforms.
