For your first I woul stick with wood. Or even plywood if no experience with glass/carbon.

The core is selected for rider weight, so....

I agree with downunder. Make a wood core board. Most manufacturers make wood core for a reason. 1) Its robust for impact damage 2) ease of construction, 3) flexibility.

Foam core is good in an instance where you want stiffness and complex when you want flex in your design. A TT requires some flex. Rolling with wood core will give you that flex with less change of delamination failure.

As for thickness, measure up some your boards locally and get an idea of tip thickness to center section thickness. My board have 4.5mm thick tips and 8mm thick center section. I'm running carbon fibre reinforcement with bamboo core.

Plywood boards are easy to build and can perform comparably to production boards if constructed properly. For a inexpensive board, get some birch plywood at the local lumber supply store that approximately has the rocker you want. Then use T-nuts for the pads/straps. I epoxy laminate layer of fiberglass cloth on the bottom (one or two 6 oz. depending on what stiffness I want. Made my own fins from the same plywood. See pics below.

If you insist on using a corecell, it is a fine material for building kiteboards.

I would say use 12 or 15 mm for your first attempt.

I built a couple dozen boards using 9 mm corecell but they all had a 3mm bottom concave moulded in to make the boards stiffer and sweet.

If you don't use a good mould, and prefer to shape the bottom or leave it flat, you will want to have a core thicker than 9mm.

I used 10mm thick Gurit M foam for mine. I think about 12% density.
And a 200mm wide unidirectional 600 gsm glass top and bottom down the middle over polyester print fabric with biaxial glass over that and then regular glass weave over that.
Mine came out pretty light but I was doing resin infusion.(under vacuum) The glass fibre gives some stretch which I wanted.
