PROBLEM TO BE SOLVED: To manufacture the complex three-dimensional shape curved surface honeycomb panel. SOLUTION: When forming the curved surface shape, the honeycomb panel 9 manufactured by joining partially a honeycomb core material and back surface sheet material and front surface sheet material interposing the honeycomb core material in the state of a flat plate as primary working, is subjected to press working to the prescribed curved surface shape and the three-dimensional shape. After that, by arranging the honeycomb panel 9 after the press working in dies in the shape of a product shape as secondary working, the honeycomb core material is subjected to a plastic deformation by hydraulic bulging. |
