I think the wood Zob is using is called Durakore. End grain balsa wood with thin hardwood veneer laminated on top and bottom. ATL Composites is the only place in the US i have seen it advertised. I think it might be less expensive to laminate some pieces up yourself.

I don't think it is Duracore, what I am using (couldn't find a decent pic of it). However this is a great find, because this kind of companies could use what I am using for their packing sheets. They usually don't know what they have or what it is made of. It is just packing material for them and a high valued ply for me. And they set the price, which is low :D .

It sounds like the wood zob is using is the cheap luaun used to wrap around palletized goods,
If so you can find it at loading docks, hopefully before they tear it off the crate. The problem with stuff like this I have seen is that the core, which can be 80-90% of thickness, can have voids or cracks in it. Also probably doesn't have waterproof glue. But it's light...

well, waterproof glue is not issue due to the fact that i will wrap it entirely in glass and epoxy !

voids are and isue tho !

as for my rescearcs, blasa DIY core with or without stringers is the way to go ( but it needs tools and a balsa suply !!!)

for comparison look at the way

John B built a hollow cedar strip kiteboard:

or the way Burt Burger builds Balsa Skined surfboards:

or paul jensen hollow boards:

or the ultimate, Aviso hollow boards:

it all works.

this is a bit off topic.
but i think you'll find this thread interesting.
its a low tech (compared to high tech) approach to the different fabrication techniques you've been considering.

Curious how the avisos hold up to the wave puntings during kiting compared to a sandwhich construction of similar weight.

If you make the sandwhich beam thick enough with enough dent resistance it should be fine. but in general large flat hollow carbon structures don't like to be jumped upon.

Figured a carbon skin honey comb core would be ultimate ideal, weighs nothing has good compression resistance and skins are fully supported...... it's just really expensive and not terribly good for shaping.
