Abstract (AI)
In this paper, we present strain monitoring of a filament wound composite tank using fiber Bragg grating (FBG) sensors during hydrostatic pressurization. 20 FBG sensors and 20 strain gages were attached to the domes and cylinder of the composite tank. A wavelength-swept fiber laser was used as a light source to supply high signal power. From the experimental results, it was successfully demonstrated that the FBG sensor system is useful for large structures that require a large number of sensor arrays.
Key Findings
1
A wavelength-swept fiber laser provided high optical signal power for the FBG measurement system.
2
Strain monitoring of a filament-wound composite tank was demonstrated during hydrostatic pressurization using fiber Bragg grating (FBG) sensors.
3
The experiment deployed 20 FBG sensors and 20 conventional strain gauges on the tank’s domes and cylindrical section.
4
The results demonstrated that the FBG sensor system is suitable for large structures requiring many distributed sensors.
