Abstract

A spatial modulation technique applied to embedded fiber optic sensorfor real time monitoring of 3-D braided composites, is presented. Several 3-Dcomposite specimens with embedded fiberoptic sensor have been fabricated and tested.Optical fibers were incorporated into the structure during the braiding process. Thestudy shows that; (i) the spatial modulation technique is applicable to optical fibersbraided into 3-D composite structures, and (ii) it is preferable to use special geometricalconfigurations of the embedded optical fiber, to improve the sensor sensitivity anddynamic range.
