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.

A method of manufacturing a pair of foam core panels having improved sound absorption characteristics which comprises the steps of: forming a foam panel between a top and a bottom means which dimensionally limit the thickness of the panel, said panel having a nonuniform cellular structure such that the panel has a large cell structure at a center portion and smaller cell structure at the top and bottom portions of the panel; and skiving the foam panel through the center portion having the large cell structure to make two panels each having an exterior surface that has a large cell structure and has open cells to thereby improve the panels sound absorption characteristics.
