The paper presents the results of investigations of acoustic properties of polyvinyl chloride (PVC) composites with the nanodimensional filler Cu formed as a result of an electric explosion of the conductor. It is shown that at the longitudinal, shift, and volume deformations at the frequency of 0.4 MHz in a wide range of temperatures, and the content of ingredients, the formation of viscoelastic properties of a material takes place due to the interaction on interface of the phases of the polymer filler as well as to certain topological effects. Direction of usage of PVC systems at dynamic and temperature loadings are specified.
Keywords: electric explosion of the conductor, ultrasonic field, viscoelastic modules, energy dissipation, nanocomposites.
