Abstract

A honeycomb sandwich panel is produced by (a) mounting a honeycomb core on a lower prepreg laminate skin placed on a forming die, (b) superimposing thereon an upper prepreg laminate skin to cover the honeycomb core, (c) mounting flat plate-shaped elastic jigs on a portion of the resulting assembly where the lower prepreg laminate skin and the upper prepreg laminate skin are overlapping each other, (d) superimposing flat plate-shaped press jigs on the elastic jigs, and (e) heating the assembly under pressure for adhesion forming.
