Acoustic emission (AE) techniques have been applied to the development of GFRP dewar vessel. The monitoring systems were thought to be inevitable in developing GFRP dewar vessel in order to estimate the durability and safety of the dewar. Furthermore, systems are important to investigate the causes and to locate the troubles for the repairment.
GFRP dewar made by adhesive bonding method has been developed and the durability has been monitored by means of AE method during the transfering the coolant and pressurise tests. It is found that the condition of coolant and vacuum leakage could be detected in terms of AE method.
