| Research Abstract |
In order to ensure the integrity of GFRP vessels, ultrasonic testing method which is based on the evaluation of transmitted waves from the outside of the vessel is applied. It is found that in the early stage of degradation, inspection with through-thickness wave propagation is more reliable than that with in-plane wave propagation. It is also found that application of Acousto-Ultrasonic parameters improves inspection accuracy.
