Abstract
An automotive vehicle vibration reduction and damping system for use in an automotive body panel assembly having an inner body panel and an outer body panel is disclosed. An expandable material, such as a polymer-based foamable material, is disposed on at least one edge of a damping member mounted to at least a portion of the body panel assembly. The system is activated as the vehicle undergoes the final vehicle assembly process and paint operation which activates and transforms the expandable material to expand, bond and structurally adhere the damping member with the body panel assembly for vibrational damping and noise reduction.
