Honeycomb core is made by bonding sheets of foil and expanding them.
Another source of error is the presence of an adhesive material between the foil sheets which has a much lower modulus than aluminum.
Your model uses bonded contact to connect the foil sheets to make the 2t thickness instead of adhesive, so your model has a higher modulus than the physical product.
