| Abstract: | Composite plate and shell with rubber liners can analogize real filament wound pressure vessels. By comparing time history and frequency domain curves of the impact on the composite materials, defects, between liner and winding layers as well as between liner layers in this kind of plate have been inspected. For example, a propotional reduced sample of a certain type of the rockec motor case has been detected. |
