Inner defects testing of winding layer of composite gas cylinder
Composite gas cylinders have the advantages of light weight,high strength,good corrosion resistance and fatigue performance,but the current national standards for composite gas cylinders are mainly based on macroscopic inspection,searching for internal and external surface defects.Inner defects of winding layer cannot be detected.In this paper,the influence of inner defects on composite gas cylinders was analyzed.Three kinds of testing methods for inner defects of winding layer were compared to provide reference for periodic inspection of composite gas cylinders.
