EFFECTIVE VIBRATION DAMPING ACROSS A BROAD TEMPERATURE RANGE

Title:

EFFECTIVE VIBRATION DAMPING ACROSS A BROAD TEMPERATURE RANGE

Document Type and Number:

WIPO Patent Application WO/2012/170671

Kind Code:

A3

Abstract:

Assemblies, methods and systems useful for reducing the noise and vibration characteristics associated with hollow spaces or cavities of vehicles by positioning damping foam material within and spanning the space between a first substrate surface and a second substrate surface. The damping foam material is comprised of a first region and a second region, wherein the first region has an E' value at -10°C that is lower than the E' value at -10°C of the second region and an E' value at 25°C that is higher than the E' value at 25°C of the second region; and the second region has a variable cross-sectional width.
