The influencing of ultrasonic deformation εUS was researched on unelastic and elastic characteristics of nano composites of multiwalled carbon nanotubes (MWCNT). The criterion of structural relaxation is formed: inelastic structural relaxation can be caused only the that defect of structure, the system of symmetry of which below the symmetry of crystal. It does not determine the effect value of relaxation [1].

The increase of the nano composite crystalline degree at growth of multiwalled carbon nanotubes concentration filling with the nanotubes of matrix results in the decline of content of well-organized phase.
2. The growth of heights internal friction maximums Q-1M testifies the growth of structural defects concentration in nano composites.
3. The annealing of the structure defects in nano composites bends out of shape the type of internal friction temperature spectrum Q-1(Т).
