Abstract
A composite panel having a non-adhesion portion is mounted on a stationary table and a bending table and is fixed thereto by vacuum adsorption pads. An upper portion bending table is mounted on a face sheet providing the non-adhesion portion. The face sheet is secured using the vacuum adsorption pad on the bending table. The bending table is rotated, so that the face sheet is bent. The center core member is cut with a V-shape. An adhesion agent is coated. Next, by rotating the lower bending table, the other face sheet and the center core member are bent so that the core member is adhered to the upper face sheet. Without causing a gap between a face sheet and a center core member and a partial contact, an integral bending processing of a flat sheet shape composite panel can be realized. In addition to this, to assurance adequate strength in a bending processing portion of the composite panel, it is unnecessary to provide a separate member and the like.
