Abstract

The transmitted spectrums of conventional FBG sensors operating in near infrared region (Bragg wavelength ~ 830nm) embedded in E-Glass/Vinylester composite sample were investigated at static and after fatigue loading. Also transmitted waveforms of a FBG attached to a surface of single layer E-Glass/Vinylester composite sample which has a purposely created hole closer to attached FBG sensor were examined in order to understand the FBG response in a vicinity of a void/damage, under static loading situation. As a consequence, some conclusions were made on the sensitivity and durability of the use of FBG sensors fabricated by conventional writing techniques in long term health monitoring system of composite structures.
