The basic structural factors enabling the design of high-modulus and high-strength nanocomposites (polymer/carbon-nanotube) with mechanical characteristics analogous to the corresponding parameters of steel are studied in the framework of fractal analysis and percolation theory. The main factor is the formation in the polymer matrix of carbon-nanotube tows consisting of many of them with a structural fractal dimension close to Euclidean (close to three). Such tows have an elastic modulus close to the nominal value of a separate nanotube. The proposed procedure allows the limiting mechanical characteristics of nanocomposites to be determined.
