This question is impossible to answer from the given information..
I have built CF "disc-wheels" using two very "flat cone-shaped" sheets of Carbon-fibre-Epoxy bound composite. They were bonded using Permabond, both at the centre and around the edge, to a CF wheel rim.
The first set of "wheels" were used and tested to destruction on a cycle-cross bike.. The rider weighed around 80 kg .. but the "impulse" loads from riding on rough tracks would have been much higher. The "cones" were 1 layer of 200 gsm twill + 1 layer of 300gsm Biaxial CF. Destruction occurred because of failure of the bonding to the aluminium wheel hub.
A single free-standing 700 mm diameter disc of CF reinforced composite WILL bend and buckle under a very light load..
Two pieces of 2x200gsm twill fabric with 5 mm of Aluminium Honeycomb (small cell grade 5000 alu) in between will easily support more than 75 kg (my weight.. ) on the edge .... no visible distortion at all.
The piece i tested is 7 cm tall and 5 cm wide, and weighs 5 grams ...
It did not fail, even though I have already pre-buckled one side with an indentation, caused by testing compressive strength by putting 75 kg/sq-cm of localized pressure on it. This caused a 0,7 mm depression in the laminate.
