A headliner is a composite material that is adhered to the inside roof of automobiles or yachts. It typically consists of a face fabric with nonwoven or foam backing. Headliners consist of multilayered composite materials that bring together multiple functionalities, including the requested look, feel, stiffness, and sound reduction needed in cars. Automotive headliner is optimised with respect to head impact counter measure or to integrate additional LED lighting film behind the fabric. Most headliners consists of a tricot knit fabric that is knapped to provide a soft touch and uniform appearance. The fabric is adhered with melted polyurethane foam. This fabric-foam composite is glued to the interior fiberglass roof of the automobile.
There are more complex knit products used as a face fabric, as well as less expensive non-woven products. Recent headliner developments include environmentally friendly products made of recyclable backing-adhesive and face fabric.
In yachts, foam-backed vinyl is often used.
