Abstract

Metal-matrix composite structural components' subsurface strain and temperature levels can be ascertained by means of embedded fiber-optic sensors, if these can be incorporated without degradation in the course of composite fabrication. Attention is presently given to a USAF program for the embedding of fiber-optic sensors in Ti-alloy matrix composites, whose severe conventional processing conditions are broken down into less severe steps. It is noted that the sensor fiber used should be of a composition optimized to minimize dopant migration, and should incorporate abusive processing-resistant coatings.
