Abstract
A flat unitary composite carpet structure which can be hot molded permanently into non-planar shapes conforming to contoured surfaces such as automobile floors has an exposed textile surface to the underside of which is adhered a relatively thick layer of polyurethane foam which provides good fiberbonding, tuftbinding and sound deadening qualities to the composite carpet structure, and to the underside of the polyurethane foam layer is adhered a relatively thin layer of polyethylene which provides good shape retention qualities to the composite carpet structure and provides means for adhesively attaching an underpad to the carpet structure as the latter is hot molded to conform to the desired contoured shape.
