Abstract

The focus of this article is on analyzing the behavior of pressure vessels by acoustic emission testing (AT) and assessment of the ability of experimental methods in detection of cylinder defects by measurement of strain on FRP composite tanks. To perform the experiments, the set-up is prepared by installing acoustic emission sensors and strain gauges on the composite tank. Then, the data is collected from acoustic emission sensors and strain gauges. It was observed that the composite tank was in the safe range at pressures less than 2 bar and holes up to diameters of 2-mm diameter did not lead to plastic deformation and development of defects. Under other operating conditions, no monitoring is necessary up to pressures of 5 bar or less where the strain dies bit act linearly any more. At higher pressures, it is necessary that other failure mechanisms, such as elastic-plastic deformation, cracking, etc to be monitored. It is concluded that the acoustic signals are mostly produced by failure mechanisms. The acoustic emission signals for a non-defective cylinder are much less than a defective cylinder. The signals usually start to show up when at the incipiation of a leakage.
