摘要：

This paper presents the results of experimental studies of damage accumulation in a metal-composite pressure vessel by pneumatic strength tests. The deformation and fracture of the composite structure accompanied by matrix cracking and fiber rupture are analyzed. It is shown that the cracks and fractures generate acoustic-emission signals of various types. The results of acoustic-emission monitoring were used to develop a criterion for ranking vessels according to the strength characteristics of the pressure composite shell.
