Abstract

See full text

A shaped honeycomb structure having a permanently fixed fold portion. The shaped honeycomb structure has a honeycomb core with a plurality of abutting partition walls defining a plurality of abutting hollow cell faces on a top side and a bottom side of the honeycomb core. The fold portion defines a first panel portion converging with a second panel portion. At the fold portion, the partition walls are generally not vertically deformed. The shaped honeycomb structure may be made by a method comprising expanding an unexpanded honeycomb core to form an expanded honeycomb core comprising a plurality of abutting partition walls forming a plurality of cells defining a plurality of abutting hollow cell faces on a top side and a bottom side of the expanded honeycomb core. The expanded honeycomb core is impregnated with a resin. The fold portion is formed in the expanded honeycomb core such that the partition walls are generally not vertically deformed at the fold portion. The resin impregnated folded honeycomb core is then completely cured to permanently rigidly fix the plurality of abutting partition walls into the plurality of abutting hollow cell faces with the fold portion.
