Description

Acoustic emission (AE) allow to receive the additional information about the process of miсrocracks. Poisson coefficient μ is equal to ratio of relative transversal compression ε┴ to relative longitudinal lengthening ε║.
Complex elastic module of polyamide (NH(CH2)5CO)n, polyethylene (C2H4)n, polyvinyl chloride (C2H3Cl)n, porous polystyrene C8H8 nanocomposite Е* is equal to the sum of dynamical elastic module E’ = ρV2║ and loss module E” = E’δ [1,2].
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.
As the result of the mechanical study the presence of the strong effect between low-density polyethylene (C2H4)n, polyvinyl chloride (C2H3Cl)n and multiwalled carbon nanotubes was confirmed.
