Abstract
A self-supporting headliner panel for lining the interior surface of an automotive roof comprises a front sheet, a back sheet and an intermediate corrugated sheet adhered to the front and back sheets. The front sheet and the back sheet each comprise wood fibers and polypropylene. To form the panel, a laminate of the front sheet, the back sheet and the intermediate corrugated sheet is molded in a heated mold which melts polypropylene fibers in the front and back sheet causing the laminate to conform to the shape of the mold and adhering the three sheets together.
