A panel assembly that includes a main panel, a sound-damping patch, a sound-damping adhesive layer, and a structural adhesive joint. The structural adhesive joint may be used in place of spot welds, clinched joints or other metal joining mechanisms that would prohibit the panel assembly from being used in certain applications, such as class A surfaces on a vehicle that can be seen or touched by a customer.

Panel assembly having structural adhesive joint

A sound damping material for use in a sound damping laminate having one or more rigid layers, such as those used in the automotive industry. The sound damping material is preferably a viscoelastic material that damps or otherwise inhibits the transmission of vibrational or acoustical energy through the laminate, and also acts as an adhesive for bonding the rigid layers together. In its cured form, the sound damping material layer can include an acrylate-based polymer matrix, and one or more of the following components: a precipitated phase, a viscous phase, and miscellaneous constituents. The acrylate-based polymer matrix is the reaction product of at least one acrylate-based monomer, such as isobornyl acrylate.
