Abstract
Fiber optic sensors offer the potential for measuring strain and monitoring the cure cycle and service life of filament wound composite motorcases provided that successful methods for embedding the fiber optic sensors can be developed. The proposed Phase I research program will investigate techniques for embedding fiber optic sensors in filament wound composite structures. A primary focus of this research will be to evaluate the effects of different optical fiber types, coating methods and sensor locations (i.e., orientation relative to composite ply directions) on the structural integrity of the composite. The feasibility of incorporating the fiber optic sensors into conventional filament winding processes will be evaluated. As part of the proposed research activity, analytical models will be developed to provide a methodology for evaluating the stress/strain stare for different fiber optic sensor configurations. Filament winding trials on simple cylindrical geometries will be conducted to assess fabrication feasibility. Final configurations will be selected for further demonstrated and testing in Phase II.
