ABSTRACT:
The core of a honeycomb panel consists of a set of corrugated strips each of which alternate abut the immediately adjacent strips. Interlocking protrusions are formed in the abutting portions of the strips. The protrusions provide automatic registration of the strips without jigging or fixturing. Preferably the protrusions are somewhat undercut to provide a detent or snapping action upon assembly to provide mechanical integrity prior to bonding. The snapping action also holds the abutting surface together for uniform bonding. Lateral registration of the strips can be provided by, for example, forming a lance and window or mating dimples in the abutting surfaces. Bonding of the abutting surfaces can be done by soldering, brazing, or gluing. This honeycomb core structure is suitable for the continuous fabrication of panels of arbitrary length, width, and thickness.
