The calculated estimates of the strength and deformation characteristics of carbon composite materials based on carbon fibers with polymer, carbon and carbon-ceramic matrices obtained by various technologies are presented. The calculation method is based on the structural model of the strength of the composite material as a “bound” beam of reinforcing fibers. Good agreement of the calculated data with the experimental results indicates the applicability of the calculation model used for the design of new materials and products. It is also shown that the isostatic technology of obtaining carbon matrices based on coal pitch allows to obtain carbon composites with properties closest to carbon plastics, which are characterized by the best ability to realize the strength of reinforcing fillers.
