Composite or multicomponent materials are widespread in the aviation and automotive industry since they compete with metals in their characteristics but weigh much less. Due to this multicomponent composition, it is difficult to test the quality of such materials. Materials can contain very small hidden defects, i.e. delamination, cracks, impact damage. Their size is literally a few millimeters. The exploitation of such products, for example, in aviation, can lead to a disaster.
