PURPOSE: To provide a composite panel having an angular bend and a bending processing method of producing such a composite panel in which the occurrence of a gap or partial contact (the local application of pressure) between the face sheet and the center core member is eliminated, so as to provide an angular composite panel having a high strength. CONSTITUTION: The bent composite panel is produced by a process comprising the steps of providing a flat composite panel comprising a flat center core member(13) having first and second major surfaces, a flat first face sheet(11) having a length substantially equal to a length of the flat center core member and being adhered to substantially all of the first major surface of the flat center core member, and a flat second face sheet(12) having a length shorter than the length of the flat center core member and having a first end portion adhered to a first end portion of the second major surface of the flat center core member, and a second end portion including a second end terminating short of a second end of the flat center core member, the second end portion of the flat second face sheet not being adhered to the second major surface of the flat center core member; bending the flat second face sheet at a bending position so as to bend the second end portion of the second face sheet away from the flat center core member; cutting a V-shaped cut-out in the second major surface of the flat center core member at a portion adjacent the bending position; bending the flat center core member and the first flat face sheet about an apex of the V-shaped cut-out; and adhering the second major surface of the center core member to the second end portion of the second face sheet. |
