Abstract—
Two-dimensional and four-dimensional reinforced carbon–carbon composite materials based on carbon structural filament are prepared via the isostatic carbonization of a coal tar pitch. The difference between the crystalline state of a reinforcing fiber and a coke matrix is assessed with X-ray diffraction analysis. A change in the level of the surface resistivity depending on the density of the samples and the degree of graphitization of a matrix is studied with eddy-current testing. We show that the degree of completion of formation of the internal structure influences the mechanical strength and the level of specific electrical resistance of the material. Measurement of the electrical resistivity with eddy-current testing appears to be a non-destructive method to assess changes in the structure of the material.
