Damage inspection for a composite cylinder using a thermography test during air injection
Due to its high strength and low weight, fibre-reinforced plastic (FRP) is often used to manufacture gas cylinders. However, impaction, striking, burning and maturing can all damage FRP and expose safety risks, which are difficult to inspect with common non-destructive testing (NDT) methods. Moreover, it is difficult to identify FRP damage with traditional NDT methods. In this paper, thermography testing, which is a type of NDT method, was applied to solve this problem as it has been extensively used in non-metal material tests. The principle of this method is that a heating phenomenon occurs when air in a cylinder inflates. To explain the method, several numerical simulations and laboratory experiments were performed. The results show that the proposed method exhibits good performance in detecting and quantifying a defect in an FRP layer. Considering the effects of the method, there is a broad future for its actual application.
