CURVED SURFACE-LIKE BRAZING SANDWICH PANEL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a curved surface-like brazing sandwich panel for maintaining a brazing connecting state between a rectangular form constituted of a frame material to be bent and a frame not to be bent and a surface plate. SOLUTION: In the curved surface-like sandwich panel obtained by disposing a predetermined core 2 at an inside of a rectangular frame 4 by using the frame 4 obtained by integrally connecting in combination two R frames 4a to be bent and two S frames 4b not to be bent, sandwiching the frame 4 and the core 2 between two surface plates 6 and bending the overall panel by bending in one direction, the materials 4b for giving such a frame 4 is constituted of the frame having lower compression strength than that of the material 4a.
