Composite Overwrapped Pressure Vessels (COPV)
potential is properly addressed in design and test. 3) Quantitative nondestructive testing methods used for flaw screening of thick-walled metallic structure are generally not applicable to COPV designs. Pressure vessels have historically been classified as failing due to either burst or leak-before-burst (LBB).
