The Need for Application of Dynamic Mechanical Analysis in the Evaluation of Interlayer Materials

Abstract

Interlayer materials like Polyvinyl Butyral (PVB), Silicone and Urethane are viscoelastic in their mechanical behavior. Mechanical properties of a viscoelastic material are not only dependent on temperature, but also highly dependent on frequency or strain rate. Dynamics mechanical analysis provides an effective experimental tool to measure the viscoelastic properties over a wide range of temperatures and in the time range of a few seconds up to 10 to the minus 5th power seconds. It is especially suitable for studying the viscoelastic nature of interlayer materials since the temperature and strain rate conditions for windshield design and service are within the measurement and analytical capabilities of DMA.
