ABSTRACT:
A method of manufacture of a foam core board is described as well as vehicle trim panels made from such board. A foam board having a cell structure including a structure with large cells in a center portion is initially formed. This board is skived into two separate panels, each having one surface with relatively large cell structure and wherein said cells have been opened by the skiving process. This surface acts to promote enhanced sound absorption from the foam core board. This board may be laminated with appropriate decorative material and molded to make contoured resilient vehicle trim panels.
