| The paper deals with estimating the frequency and temperature dependences for the decrement and relative change of the Young's modulus of the PVC-systems containing superfine filling compounds for different values of the attenuation constant of energy of mechanic vibrations. The results of the study of systems' dynamic properties in frequency ranges of 20-500 Hz and 0.8, 1.8, 2.5 MHz have been presented. The recommendations for controlled regulation of viscoelastic properties of the composites on the basis of amorphous polymeric compounds have been given. |
