摘要 PURPOSE:To provide a ceiling material for a vehicle and a method for manufacturing the same which uses lighter and smaller in quantity material to be used than that of prior art, has large rigidity, can supply a low-cost and a large quantity of product of a high quality and can be easily handled and has excellent corrosion resistance, weather resistance, and can be recycled. CONSTITUTION:A ceiling material for a vehicle comprises a protective layer 11 made of thermoplastic resin mixed with fiber in a range of 40-80% of volumetric content on front or both front and rear surfaces of a core material 12 of a flat plate state made of resin foam, and a surface material 13 laminated. A method for manufacturing the ceiling material for the vehicle comprises the steps of heating a material sheet of the layer 11 made of thermoplastic resin mixed with fiber of 40-80% by volumetric content to a glass transition point or higher of the resin, superposing a core material sheet made of the foam and the surface material, pressurizing and shaping it by molds.
