Strain monitoring of the composite high pressure tanks using the FBG sensors
광섬유 센서를 이용한 복합재료 고압탱크 변형률 측정
Abstract
The FBG sensors are inserted on the liners of the filament wound pressure tanks. The strains near the welding region of the liners are monitored in the hydro-pressurizing tests. The hydro-pressurizing tests consist of the proof tests at 4500 or 3300 psi and repeated test at the operating pressure, 3000 psi. The FBG sensors work well under
