Abstract
It has been shown that the thermal conductivity of phenylon-based carbon fiber can be described within the framework of fractal analysis. Depending on the size of the core (system) of filler fibers, such a description can be obtained by applying two limiting cases: a case-specific network of resistors and a random superconducting network. It is obtained that in the case of a superconducting network, the thermal conductivity coefficient is controlled by the fractal dimension of the walk or the number of available places for this process of the core of the filler fibers.
