Notes:
Composite pressure tanks are rapidly expanding in their range of use. However, for highpressure flammable or toxic gases, there is less confidence about their reliability. In this study, fiberBragg grating (FBG) sensors embedded into a composite pressure tank monitored strain and detecteddamage. The sensor heads and fiber optic lines were protected with an acrylate recoating, adhesivefilms, PVC tubes and Teflon[removed info] film to survive under the harsh environment of the filament windingprocess. During the quasi-static loading test, the internal strain was measured with embedded FBGsensor arrays. In order to detect damage occurred during the test, impacts were applied on threedifferent positions in each side by an impact hammer. The difference between damaged andundamaged sides in impact response was analyzed. An interrogation system using awavelength-swept fiber laser (WSFL) was used for measuring strain, and an erbium-doped fiberamplifier (EDFA) laser source with a tunable Fabry-Perot filter was used for measuring impactresponse
