Abstract:
1. A metal panel assembly, comprising: a sound damping adhesive layer; a body layer; and an outer layer having a plurality of contact sections that confront the body layer through the sound damping adhesive layer and a plurality of raised sections that are spaced from the body layer, wherein at least some of the contact sections that confront the body layer through the sound damping adhesive are located in an interior of the outer layer and at least some of the raised sections are arranged in a grid-like pattern so that they intersect one another, and the contact sections are arranged to help dampen vibrations and/or noise in the metal panel assembly and the grid-like pattern of raised sections are arranged to help stiffen the metal panel assembly so that the outer layer both reduces vibrations and/or noise and stiffens the underlying body layer.
