After some successes making simple parts for my westfield I am looking into a winter project of swopping out the aluminium floor to a composite one. (20 years of abuse has left the aluminum a bit dinged)
I am probably going to use Diolen for a bit of impact resistance but can I get away with a 100% Diolen stack or should I put in a carbon layer? for stiffness.
Aluminium floor is currently 1.5mm any recomendations as to a Diolen floor thickness?
Will be done with Resin infusion.
is there any issue I need to worry about while producing a larger flat sheet i.e more resin feeds or exotherms
Size will be 1m x 2.5m ish
 

Cheap compared to carbon so a good choice for the floors.

I made the floors for my Elan out of 2 layers of carbon either side of a 5mm foam core, virtually unbendable! If I made them again I would use 3mm foam and a lighter carbon as they are overbuilt. Standing on the floor (which was simply sitting on the chassis frame) and there was no discernible deflection.
