6th European Workshop on Structural Health Monitoring. Dresden. Germany. 2012. Report. In this work, composite materials were instrumented by optical fiber sensors with the scope to monitor the instrumentation of pultruded profile made out of composite materials. Then after, using Fiber-Bragg Gratings, were used to monitor strain under quasi-static and fatigue loading under 3-point bending. Results show that optical fiber sensors perform well in either cases. The results that are reported are part of the French Program decid2 aiming at building a large dimensions plateform (20m x 3,5m, DECID2 Project).
