Abstract
A fiberoptic sensor, based on the extrinsic Fabry-Perot interferometer (EFPI) design, was developed for intelligent processing of epoxy matrix composite materials. The EFPI sensor is modified so that, when embedded in a composite material during fabrication, it will output a signal that is proportional to the degree of polymerization (cure state) of the epoxy. After cure of the epoxy, the sensor may be used to measure initial strains.
