Title: Novel method for sensing Structural Health of Composites
Agency / Branch: DOD / ARMY
Contract: DAAH10-03-C-001
Award Amount: $120,000.00


A novel method that uses the measured electrical resistances of a composite structure only along the edges of the structure is proposed to monitor its health. The major advantage of the proposed innovation is that it is practical, it minimizeswiring/cabling and it does not require any additional sensors to be embedded within the composite. Not embedding sensors in the composite maintains the strength and integrity of the structure and reduces cost. In Phase I Mid¿ will refine its patentpending algorithm that estimates the internal resistances of a grid-like network for this application. The method will be laboratory demonstrated on simple composite plates and a test article that will be used to demonstrate the technology in Phase IIwill be identified or designed in Phase II. In Phase II feasibility will be demonstrated on more complex composite structures and on existing pr fielded systems. Phase II will also design, fabricate and package the required electronics. The ability todetect the health of composite structures in situ or during maintenance with a method that does not require any significant modifications to the composite will enable the ability to cheaply monitor the structural health of composites. The research willlead to two new products. The first being a suite of instrumentation products to be used by composite manufacturers and the second being the diagnostic hardware/ software that will be sold to maintenance facilities.
