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.
