Abstract
A laminate product particularly useful in vehicular applications is described. The laminate product comprises a foam core having a first major surface and a second major surface. One or both of the major surfaces comprises a fibrous layer and an adhesive layer adhering the fibrous layer to the foam core. The process for producing the laminate product involves exposing an initial laminate product to infrared radiation. A portion of the adhesive layer between fibers in fibrous layer being ablated. The foam laminate product has improved sound absorption properties and while maintaining desirable strength and stiffness properties. In addition, in certain cases, the peel strength of the fibrous reinforcing layer to the foam core is significantly improved in the present foam laminate product compared to the conventional approaches.
