Abstract
A percolation model of nanocomposite reinforcement is under study. It is shown that the degree of reinforcement of polyurethane - carbon nanotube nanocomposites depends on the structure of nanofillers, which are annular formations. This structure is most accurately characterized by its fractal dimension. It is established that the creation of a structure with negative percolation indices allows for a significant increase in the degree of reinforcement of considered nanocomposites at low nanofiller concentrations.
