Emission in Using Hoop-Wrapped
Composite Cylinders

Abstract Hoop-wrapped composite cylinders for Automotive Vehicles increase
rapidly in recent years. At present, several major accidents of hoop-wrapped
composite cylinders for vehicles has happened in China, therefore the compressed
natural gas cylinders is the most serious. In the regular inspection, the higher ratio
of surface defects have been found in Hoop-wrapped composite cylinders for Automotive Vehicles, at the same time, the surface of broken hoop-wrapped composite
damage in cylinders is much higher than in the past few years. In use, hoop-wrapped
composite cylinders will be defected which is caused by collision with the vehicle
surface damage, affected the hoop-wrapped composite cylinder’s safety. Therefore,
it is necessary to find an on-service nondestructive testing method for the hoopwrapped composite cylinders. Consequently, we study the Acoustic Emission (AE)
signals characteristics of the hoop-wrapped composite cylinders during the fatigue
process and the air tightness process, and using process, and defects recognition
method preliminarily is advanced. These studies have important significance for realization of AE on-line detection and fault diagnosis of the hoop-wrapped composite
cylinders.
34.1 Introduction
The hoop-wrapped composite cylinders have been widely used in various industries such as aerospace, petrochemical and automotive industries [1, 2]. However, in
the recent years, there were been several serious major vehicle compressed natural
gas cylinders accident, in which the hoop-wrapped composite cylinders is the most
serious. In the regular inspection, the certain ratio of harmful surface damage has
