Abstract	The paper introduces a diagnostic technique making possible the research of internal structures in composite material (CFRP – carbon fiber reinforced plastic) that is used more often in construction of light armors protecting vehicles. Little mass and the resistance against the perforation with bullets and fragments are basic requirements of contemporary armors. This requirement could be met by using composites. Composite armor is examined by testing its ballistic resistance and this is performed by carrying out bullet proof tests. During this test in the moment of bullet’s striking into armor the composite material comes into destruction of its internal structure on a considerable area. This is especially visible in multi-layer composites. It causes so-called delamination which is characterized by the loss of interlayer cohesion and destruction of continuity of polymer matrix in which the fiber is embedded. Delamination appears both in the case of full and partial penetration of bullet. The composite material is practically destroyed in area of delamination. This is very difficult to evaluate the size of delamination area from outside because in most cases external symptoms of
