Abstract: A vehicle headliner material includes a stiffening layer for reinforcing each side of a thermoplastic resin layer so that the material satisfies required bending stiffness while having lighter weight and thus can prevent safety accidents that may occur due to increasing of headliner material weight. In particular, by using a glass mat, with a thermoplastic resin sheet on each side thereof, that constitutes a part of each stiffening layer to reinforce structural stiffness of the material, the vehicle headliner material has improved formability, improved flexural strength, and direct adhesion without an additional adhesive or the like. Also, by not using polyurethane foam to prepare the vehicle headliner material, problems such as generation of dust derived from processing polyurethane foam into sheets can be eliminated, and safe and pleasant working environments can be provided for workers.

Abstract: A vehicle headliner material includes a stiffening layer to prevent moisture penetration by reinforcing each side of a natural fiber layer. In this way, the natural fibers can be prevented from holding moisture, and thus safety accidents that may be caused by increased weight of a headliner material or a headliner being permanently deformed due to the headliner material that repeats holding and releasing moisture can be prevented. The vehicle headliner material is provided with improved formability, improved flexural strength, enhanced structural stiffness, and direct adhesion without an additional adhesive by including a synthetic resin in the natural fiber layer along with natural fibers and using a glass mat and thermoplastic resin sheets as constituent materials of each stiffening layer.
