Abstract
In-situ fiber optic and acoustic waveguide sensors can monitorprocesses such as composite cure or microstrain in large aerospace structures. Thesimultaneous response to temperature and strain in optical fibers has been exploited tocreate a single-fiber dual sensor using a single light source that can measure bothtemperature and strain independently. With the use of lead-in/lead-out fibers, thesemeasurements can be performed over a localized region. The use of acousticwaveguides as sensors have shown their ability to monitor both graphite/epoxycomposite cure and post-process pressure-induced cross-ply strains.
