Research of composite over-wrapped pressure vessels for space application

The latest development of composite over-wrapped pressure vessels （COPVs） for space applications are summarized based on a study of published literatures and some typical samples on applications of overseas spacecrafts are introduced in this paper. Besides, some valuable information about the metal liner, fiber and resin matrix of COPVs is presented respectively. R＆D and application trends of cryogenic composite pressure vessel are described. The properties of the metal liner and fiber behave very well in cryogenic temperature environment. The selection principles of resin matrix in cryogenic temperature environment are pointed out emphatically. The research status and prospect of nondestructive detection for COPVs are discussed. It is pointed out that COPV NDE technologies will advance to high efficiency, real time, precise positioning, quantitative analysis and overall defect detection.
