Abstract

PURPOSE:To avoid the internal irregularity of a composition by a method wherein the changing speed of a distance between hot plates is detected to effect the heating control of the hot plate by the detected value in case the formed body is hot-pressed between a pair of hot plates. CONSTITUTION:In case a laminated body Z wherein a plurality of prepregs 2 are laminated is hot-pressed between a pair of hot plates 1, the changing speed of the distance between the hot plates 1 shows the temperatue difference between the inner and outer sides of the laminated body 2. When the changing speed is small, the temperature difference between the outer and inner sides is small, on the other hand, when the changing speed is high, the temperature difference between the outer and inner sides is large. Utilizing the above-described nature, a differential transformer 5 detects the distance between the hot plates 1 and changes it into an electric signal while this signal is changed into the changing speed by a hot plate distance changing speed computer 6 to effect the control of heating of the hot plates 1 by this value. According to this method, a form having no internal irregularity in the composition thereof may be obtained.
