A feasibility study of computerized X-ray tomography for determining the structural parameters of carbon plastics

A computerized X-ray tomography method for studying the internal structure of carbon plastics is presented. The method is based on obtaining the density matrices of the composites in the examined cross-section. The statistical data obtained by this method make it possible to estimate the distribution of elementary cell density over the thickness and across the surface of the material. Particular attention is given to specific features of the method under consideration, namely, the error analysis of the matrices of the linear attenuation coefficients (LAC). Conversion from LAC matrices to density matrices makes it possible to obtain volume curves for density variation over the thickness and across the surface of the specimens. Histograms of the density distribution in layers of the material are presented. It is concluded that the computerized tomography is an effective method for structure analysis of carbon plastics.
