Good morning,

Both nomex and aluminium honeycomb have similar cell shapes.  The nomex uses bonded nomex paper, and the aluminium uses bonded foils. They are bonded along the two opposing flats, which means those flats are 2 skins compared to the other sides of the cell.

The hexagons are designed to be as close to regular as production tolerances allow.  Especially with the aluminium honeycomb, how regular they are entirely depends on the user expanding the honeycomb.

Thanks Warren, that is a really helpful response - the extra information especially.
