Abstract:
This paper presents the results of experimental studies of damage accumulation in a metal-composite high-pressure tank in 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 control were used to develop a criterion for ranking tanks based on the strength characteristics of the pressure composite shell.
Keywords:
metal-composite tank, strength tests, damage, acoustic-emission control.
