<p>A metal panel assembly that may be used in a number of different applications, particularly those that are concerned with improved stiffness and/or reduced vibration and noise. According to an exemplary embodiment, the metal panel assembly has a multi-layer or sandwich construction and includes a metal body layer, a sound damping adhesive layer, and a metal outer layer. The outer layer is bonded to the body layer via the adhesive layer and improves the stiffness and/or reduces vibrations in the metal panel assembly. The outer layer may include a number of contact sections that confront the body layer through the adhesive layer, as well as a number of raised sections that are spaced from the body layer and increase or otherwise improve the stiffness of the metal panel assembly. In one embodiment, the raised sections resemble channels and are generally arranged in a column-like pattern; in another embodiment, the raised sections resemble ribs and are generally arranged in a grid-like pattern.</p> |
