<p>A method of forming a self-supporting contoured foam plastic laminate, including spraying a relatively flexible open cell plastic foam, preferably polyurethane, on a sheet which is to become part of the laminate, applying a second sheet over the foam layer and promptly forming the contoured laminate under pressure in a die. The disclosed laminate includes a corrugated paper sheet, wherein the corrugations extend into and are bonded to the foam layer and a relatively flexible finish sheet bonded to the foam layer. In the disclosed automotive headliner, the corrugations extend perpendicular to the headliner side edges, providing support for the concave midportion of the headliner and preventing delamination of the paper and foam laminae.</p> |
