Epaarachchi, Jayantha A. and Clegg, Richard E. and Canning, John (2007) Investigation of the use of near infrared FBG (830nm) sensors for monitoring the structural response of 0/90 woven cloth/CSM glass fibre/vynylester composite under static and fatigue loading. In: HUMS 2007: 5th DSTO International Conference on Health and Usage Monitoring , 19-22 Mar 2007, Melbourne, Australia.
Conventional FBG sensors operating in near infrared region (Bragg wavelength 830nm) were attached on the surface and embedded in 0/90 Woven cloth/CSM E-Glass/Vinylester composite samples to investigate the strain response under static and dynamic loading situations. The measured responses of FBG sensors during loading were compared with both the readings from conventional foil type strain gauges and the results obtained from the detailed FE analysis of the sample. Further, the integrity of embedded sensors with the fibre layers of sample under dynamic loading was investigated. 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.
