Structural compressibility of the metalnanodisperse polymer systems

Acoustic bulletin, Vol. 17 ¹ 3, (2015) p.21-26
The paper paper deals with presenting the results of studying of structural compressibility of the metalnanodisperse systems obtained on the basis of Polyvinyl Chloride (PVC) in the Megahertz frequency range at 293≤Ò≤353 Ê. It is shown that this value is inseparably related with the volume viscosity and depends on the type and content of the nanodisperse metal as a material filler. On the basis of the offered model, it is shown that the structural part of volume deformation changes over the time according to relaxation law. The quantitative results on elastic and viscoelastic deformations at shift, stretching-compression and volume loading of a composite are analyzed.
