In article on the basis of the method of computing x-ray tomography the technique of assessing changes in the state structure of polymeric composite material under the dead load. The results of the analysis of structure changes for carbon fiber samples at the setting stage of loading are presented. Offered exploratory procedure allows to fracture propagation under the force action and to analyze the material changes depending on the presence and load levels. In addition, quantitative parameters are introduced to compare the tendency of the material to accumulate damage in various technological processes. The results of the test research show that the proposed method allows for high accuracy to analyze the behavior of the material under load and identify typical trends for the type of material and laying.
