Viscoelastic Vibration Damping Materials for Application in a Temperature Range above 150°C

Abstract:

We demonstrate a new type of viscoelastic vibration damping material with high damping performances (tan δ=E′/E′′ ≥0.3 where E′ and E′′ are the storage and loss Young’s moduli, respectively) at a high temperature range between 200°C and 250°C utilizing a special polymer resin of higher glass transition temperature corresponding to the application temperature range and larger pendant groups offering higher efficiency of the energy dissipation. In addition, the damping property of the bulk material reinforced with glass fiber will be significantly improved, where the peak tan δ value can reach 0.7. In this paper, we put the emphasis on the preparation process and properties characterization of this new type material, and try to provide a new method to fabricate a viscoelastic damping material (VDM) usable for applications in the field of high temperature vibration reduction, in contrast to the conventional ones whose damping properties will dramatically decay once the ambient temperature is above 100°C.
