An Internal Damage Real-Time Monitoring System Using CFRP-OFBG Plates

Abstract:

Composite material brings many challenges in structural health monitoring (SHM), especially in internal damage detecting. CFRP-OFBG, using Optical Fiber Bragg Grating (OFBG) sensors embedded in Carbon Fiber Reinforced Polymer (CFRP) composite structures, has been widely used in the field of structural reinforcement with smart sensing features. This work developed a real-time monitor system to detect internal damage by using dense arrayed fiber-optic sensor embedded in CFRP-OFBG. A classical triangulation procedure is selected and improved in damage location detection algorithm. Experimental results showed this design is an efficient and lightweight system in detecting internal damage for CFRP-OFBG materials.
