Effects and Nondestructive Testing Technique Evaluation of Impact Damage on Graphite/Epoxy Composite Overwrapped Pressure Vessels

Graphite/Epoxy composite overwrapped pressure vessel was used on space system widely. This type of vessel is very susceptible to impact damage, which will seriously degrade structure straight of vessels. The research result acquired by foreign corporation was presented in detail, and all kinds of NDT techniques on impact damage were compared and evaluated comprehensively.
