The invention discloses a sandwich structure composite material and a preparation method thereof, which adopt a fabric-composite material-fabric sandwich structure and can replace a ceiling complex of an automobile. The middle layer is a chloroprene rubber bonding layer, the formula of the chloroprene rubber bonding layer comprises Lanxess B210, protective wax Antilux111, magnesium oxide, stearic acid, an anti-aging agent OCTAM, phenol-formaldehyde resin MK95, white carbon black, carbon black N774, aromatic hydrocarbon oil, DOS, ETU-80, TMTD-80 and zinc oxide RA-65, the upper layer and the lower layer are fabrics, one layer of fabric is exposed outside, the layer of fabric is a polyester filament yarn woven fabric and has the characteristics of sun resistance, heat resistance, cutting resistance and the like, and the chloroprene rubber bonding layer is made of polyester filament yarn woven fabric. A stock solution coloring technology is adopted, so that the color fastness is high. And the other layer of fabric is arranged in the vehicle, is made of short fiber woven fabric, and has the characteristics of softness and good hand feeling.
