Sound absorption and insulation fiber metal corrugated plate and preparation mold and method thereof

The invention relates to the technical field of advanced composite material preparation, in particular to a sound absorption and insulation fiber metal corrugated plate and a preparation mold and method thereof. Comprising a plurality of metal layers and a plurality of fiber layers, the metal layers and the fiber layers are alternately laid, the sections of the metal layers and the fiber layers are of corrugated structures, and the corrugated structures are of sine waves; comprising an upper stamping die, a lower stamping die, an upper sealing cover, a lower sealing cover, a flow guide valve, a guide pipe, a resin tank and a vacuum nozzle. The metal corrugated plate is perforated, the metal corrugated plate and the cut fiber fabric are alternately laid, a laid and compacted prefabricated body is placed in an upper stamping die and a lower stamping die, a vacuum nozzle is connected with a vacuum pump for vacuumizing, then a flow guide valve is opened, vacuumizing is continued until resin flows through holes in
