Abstract
A laminate structure and method of forming is provided. The laminate structure includes a first metal sheet having a first thickness, a second metal sheet having a second thickness, and an adhesive core having an adhesive thickness. The adhesive core is disposed between and bonded to the first and second metal sheets. The first and second metal sheets are made of an aluminum based material and the adhesive core is made of an adhesive material also described as a viscoelastic adhesive material. The laminate structure is configured such that a ratio of the sum of the first and second thickness to the adhesive thickness is greater than either to one (8:1). The laminate structure including the viscoelastic adhesive core is characterized by a composite loss factor at 1,000 Hertz which is continuously greater than 0.1 within a temperature range of 25 degrees Celsius to 50 degrees Celsius.
