The invention provides an automobile ceiling glass fiber plate and a preparation method thereof, the automobile ceiling glass fiber plate comprises a surface lining cloth layer and a center layer, the surface lining cloth layer is a non-woven fabric prepared by mixing 50-55% by weight of polyester fibers and 45-50% by weight of hollow polyester fibers; the central layer is a needled felt and is formed by compounding the following raw materials in percentage by weight: 35-40% of polypropylene fiber, 35-40% of glass fiber and 20-30% of hollow PET (Polyethylene Terephthalate) fiber. The polypropylene fibers, the glass fibers and the hollow PET fibers are mutually wound, so that the polypropylene fibers and the glass fibers are not easy to break, and the three-dimensional structures of the two composite materials of the central layer are strengthened; due to the three-dimensional structure of the composite material, sound waves can be repeatedly reflected in the material, in addition, the hollow PET fibers can ab
