The effect of the structure of graphitized fibre materials (fabric, nonwoven, tricot), degree of compression, and direction of current flow on their resistivity was investigated. It was shown that there are local minima of the resistivity of these materials as a function of the direction of current flow. The resistivity decreases linearly as a function of the apparent bulk density of the graphitized fibre material. The value of the resistivity of carbon-fibre composites is close to the resistivity of a maximally compressed material. It was found that systems design methods can be used to optimize the engineering creation of the electrodes of fuel elements made of carbon-carbon porous composites.
