Abstract (EN): A smart material using fibre Bragg gratings (FBGs) embedded into carbon fibre-reinforced polymer for simultaneous measurement of physical parameters was designed, tested, and validated. Two FBGs were embedded in different sections of the composite sample, one fully unidirectional and the other bidirectional, which produced different sensitivities for each FBG sensor. The composite structure was characterized for strain/temperature and curvature/temperature measurements. The experimental results were compared with and agreed with finite element simulations.
