Composite embedded optical fibers for communication links

Optical fibers have been embeded in polymer and metal matrix composites for fourteen years; this work has identified methods for embedding and limitations due to fiber-matrix interactions and interconnection methods. Concurrently, breakthroughs in fiber-based local area networks have led to reconfigurable fault tolerant architecturers. By embedding the elements of such networks into advanced composites, structurally-integrated avionic circuit module and intra-aircraft high speed communication may be supported onboard future military aircraft. Such systems require the sequenced development of methods for the integration of fibers, fiber components and supporting electronics and optics into composite material systems and structures. The objective of the proposed SBIR program is to study the first phase of this development process-the integration of fibers and first-level fiber interconnect capability into polymer and metal matrix composites. Fiber & Sensor Technologies (F&S) and its university subcontractor, the Fiber & Elec Optics Research Center (FEORC) at Virginia Tech, are major innovators in the smart materials and structures field. Together, they have performed more than 100 relate embedded fiber/composite materials research programs for government agencies and aerospace companies. The proposed program will build directly upon their substantic experience embedding optical fibers and fiber communication system elements in polymer and metal matrix composites.
