The role of interactions of carbon nanotubes in their bundles (fibers) during creation of high-modulus polymer nanocomposites is shown. A transition from repulsive to attractive interactions of carbon nanotubes causes the elasticity of such bundles to increase sharply. As a result, the degree of strengthening of the nanocomposite increases. With respect to the structure, this change defines a transition from a deformation scheme of all nanotubes in the fiber to deformation of only those on the perimeter. Several technological methods for increasing the attractive interaction are examined.
