Headliners consist of multilayered composite materials that bring together multiple functionalities, including the requested look, feel, stiffness, and sound reduction needed in cars.
Automotive headliners are optimised with respect to head impact counter measures[1] or to integrate additional LED lighting film behind the fabric.
Most headliners consist of a tricot knit fabric that is napped to provide a soft touch and uniform appearance.
Recent headliner developments include environmentally friendly products made of recyclable backing-adhesive and face fabrics.
Heat, humidity, and time rapidly degrade the bond that the polyurethane foam has with the face fabric.
