ABSTRACT:
In a method and apparatus for laminating prepreg sheets, a plurality of heaters and a plurality of fans are installed beneath an operating table and a table temperature sensor and a room temperature sensor are provided in and above the operating table respectively. The heaters, fans, table temperature sensor and the room temperature sensor are controlled by a temperature control device. A face sheet is mounted on the operating table and the prepreg sheets are laminated while maintaining the temperature of the face sheet at a higher value than the temperature of the prepreg sheets, whereby the adhesive force of the face sheet becomes higher than that of a carrier sheet so that the prepreg sheet can be accurately bonded to the face sheet.
