Abstract:
The process of using viscoelastic
materials in structural elements includes many requirements and guidelines for
optimizing their damping performance. Two of these are related to temperature.
The first is the temperature range where the material is likely to operate and
the other is the maximum temperature where the material can be exposed to for a
given time duration without degrading its properties.
This paper discusses the behavior of a type of materials, perflouroelastomers, which is considered to be one of the
best in surviving high temperatures. Specifically, the damping properties for
this type of material will be shown before and after exposing the samples to
temperatures as high as 700° F for different durations of time
