Paper Abstract
The use of an embedded interferometric fiber optic sensor with an active homodyne demodulation scheme is demonstrated for the detection of propagating ultrasonic pulses in epoxy-matrix composites. Surface and embedded generation of ultrasound was accomplished by special transducers. Also reported are efforts directed towards the implementation of this in situ ultrasonic detection technique for cure monitoring in Hysol EPK 907, a room-temperature cured epoxy, and Hercules AS4/1919 composites. Similarities between the measured cure parameter, tau, and the viscosity of the epoxy during the cure process are discussed.
