METHOD FOR PREHEATING LAMINATE

摘要

The invention relates to a method for preheating a laminate structure (S) in which a plurality of polymer plates (1) and conductive metal plates (2 or 2') are laminated alternately, and a method and apparatus for manufacturing a laminated body (S). The invention allows the polymer plates (1) in the structure to be heated up to a desired temperature with a substantially uniform temperature distribution and in a short time, and also to be heated up to a specific temperature range with few temperature difference between an inner and an outer portion thereof and in a short time. The preheating method dielectrically heats polymer plates (1) by applying a high-frequency voltage in the lamination direction of the laminate structure through electrodes. The manufacturing method dielectrically heats the polymer plates (1) by applying a high-frequency voltage to the laminate structure (S) in the lamination direction through electrodes in a fashion of accommodating the laminate structure in an annular housing member which surrounds the peripheral lamination surface of the laminate structure (S), and also applies pressure to the laminate structure in the lamination direction by a pressing member at least after completion of the high-frequency voltage applying process. Manufacturing apparatus is for heat-integrating of a laminate structure, and includes an annular housing member which is made of non-conductive material, a dielectric heating member to dielectrically heat polymer plates and a pressing member to press the laminate structure in the lamination direction. <IMAGE>
