Scope

Main technical content: Due to their usage characteristics, fiber-wound composite gas cylinders are subject to long-term alternating loads and belong to high-pressure fatigue containers made entirely of composite materials. Fatigue damage is one of the main factors affecting the safe use of gas cylinders. Since the fatigue fracture process of composite materials does not show obvious deformation in the macroscopic appearance, it is extremely difficult to detect fatigue damage. Therefore, it is necessary to use non-destructive testing technology to detect defects in composite gas cylinders. This method uses infrared thermal imaging technology to conduct in-depth research on the qualitative and quantitative detection, location detection, and evaluation methods of fatigue damage in composite gas cylinders, and conducts experimental verification. Finally, a set of infrared detection methods for fatigue damage in composite gas cylinders based on infrared thermal imaging technology is proposed, and a group standard is formulated. This group standard specifies the methods and requirements for infrared thermal imaging detection of fiber-wound composite gas cylinders; it is particularly suitable for the detection of defects such as delamination, debonding, water accumulation in honeycomb structures, and rusting of the skin of composite gas cylinders. The infrared thermal imaging detection of fiber-wound composite gas cylinders in this standard mainly refers to active thermal imaging detection using thermal steam excitation. Other thermal excitation methods or passive thermal imaging detection can be carried out in accordance with this standard.
