The stuff in doors is mostly cardboard treated to be fire resistant. Not for weight bearing structural applications.
The honeycomb in pucka cfrp composite work is resin impregnated nomex, a type of kevlar. I get ali honeycomb from Hexcel, and occasionally small
quantities from SP Systems, as they're local.
For foam, you need rigid pvc, as used widely in boat building. Try Scott Bader.
Balsa core is also common, but I haven't used it for years.
