すようにしている。In order to form such a laminated composite into a desired shape, it is often the case that after bending into a predetermined shape, heat is applied to heat and harden it to solidify into the bent shape. As a conventional heating means, an oven-shaped high temperature chamber is used, and the laminated composite body subjected to a predetermined bending process is put into the high temperature chamber, and a heating step is performed at a predetermined temperature for a predetermined time. I have to.

もしばしばある。However, in such a conventional method for molding a laminated composite, when the molded product is large, the high temperature chamber for heating has to be increased in size, and the heating energy is wasted, resulting in an increase in production cost. There is a problem that it will end up. Further, when the molding shape is complicated, the heating temperature distribution becomes non-uniform, and the strength characteristics after molding often vary.
