Ferrimagnetic Additive Composite Textile (FACT) for Improved Antenna Power Radomes and Multifunction Electronics Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-029 Topic Title: Ferrimagnetic Additive Composite Textile (FACT) for Improved Antenna Power Radomes and Multifunction Electronics Proposal No.: N151-029-0644 Firm: Metamagnetics Inc. 480 Neponset Street 12B Canton, Massachusetts 02021-1938 Contact: Ogheneyunume Obi Phone: (781) 562-0756 Abstract: Metamagnetics Inc. proposes to address the Navy's need for new advanced materials and low-cost manufacturing methods in Electronic Warfare systems by developing new composite magnetic fibers weaved in high-performance ferrimagnetic-based textiles. These engineered magnetic fabrics can be used as substrates, super-strates, and protective coatings in several applications, including high performance radome structures for future advanced antenna systems. The proposed low-cost, low-loss, free-space impedance-matched magnetics fibers can be implemented in present additive manufacturing processes used by industry, as well as emerging advanced methods to enhance future antenna capabilities. Ferrimagnetic textiles can be tunable, spatially distributed, and made conformal to complex shapes for use in next generation electronic systems across many naval applications that require structural resiliency and high electromagnetics performance. Benefits: Structural fibers containing advanced magnetic particles will enable a new low-cost, high-performance class of composite materials that can be rapidly deployed in next generation antenna systems for electronic warfare. The proposed magnetic textiles will be implemented in radomes for innovative antenna solutions using established composite laminate manufacturing processes, leading to short TRL advancement, relatively low development cost and low manufacturing cost. Polymer/magnetic fibers can be engineered to possess a variety of desirable dielectric, magnetic and mechanical properties for applications in a broad range of platforms for land, sea and airborne electronics. Our textile magnetic fabrics have significant potential applications in commercial conformal structures, multifunction circuits, energy harvesting, and wearable electronics. Return
