Abstract

Hoop-wrapped composite cylinders for automotive vehicles increase rapidly in recent years. Therefore, hoop-wrapped composite cylinders for automotive vehicles increased rapidly. At present, several major accidents of compressed natural gas cylinders for vehicles have happened in China, but the hoop-wrapped composite cylinders are the most serious. In addition, in the regular inspection of hoop-wrapped composite cylinders for automotive vehicles, the ratio of surface damage has been found; at the same time, the surface of white spot damage in cylinders is much higher than in the past few years. Hoop-wrapped composite cylinders will be wound caused by collision with the vehicle surface damage in use, which affected the cylinder’s safety. Therefore, it is urgent to find an on service nondestructive testing method for the hoop-wrapped composite cylinders. Consequently, we study the acoustic emission (AE) signals characteristics of the hoop-wrapped composite cylinders during the fatigue process, and fault recognition method initially is proposed. These studies have important significance for realization of AE online detection and fault diagnosis of the hoop-wrapped composite cylinders.
