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.
Claims5
A method for producing a honeycomb sandwich panel, comprising the steps of (a) mounting a honeycomb core on a first prepreg laminate placed on a forming die, (b) superimposing thereon a second prepreg laminate to cover said honeycomb core to form an assembly, (c) mounting flat plate-shaped elastic jigs on a portion of the resulting assembly where said first prepreg laminate and said second prepreg laminate are overlapping each other, (d) superimposing flat plate-shaped press jigs, having a shape independent of the shape of said forming die used, on said elastic jigs so as to prevent slipping of said prepreg laminates during step (e), and (e) heating said assembly under a pressure of 6 to 7 kgf/cm2 for adhesion forming.
