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.
