| Abstract: | Composite plate and shell with rubber liner can simulate filament wound pressure vessels of the aircraft. The non-destructive testing for composite structure by using the stress wave technique is given in this paper.Using this method, defects between liner and winding layers as well as between liner layers have been inspected, the amplitude-frequency curves of the damaged reginos have been drawn,and the distribution of the defective regions between rubber liners is determined successfully. Finally,a proportionally reduced cylindrical case of a certain type of the rocket motor is practically inspected and a satisfied results is presented. |
