Development of equipment for direct measurement of viscoelastic characteristics in high-frequency range

Abstract

We developed equipment for direct measurement of viscoelastic characteristics in high-frequency range without applying the time temperature superposition principle. We proposed the first resonance compensation method to know viscoelastic characteristics in the high-frequency range. The result confirmed that the directly measurement obtained using the proposed equipment and compensation method reflect accurate viscoelastic characteristics up to 6.5kHz with less than 8.2% error.
