i want know ,how to can simulate the thickness of cloth carbon fiber and epoxy resin?
thanks!

Your English is better than my Italian.

I think you want to make a 2 part mould with a cavity that is the correct thickness for the part you are making.
I have never used it but I think you want this.

thank you brian, for answer me!  yes you have perfectly understand ,that i want build....  this sheet which you show me ,i think which is perfectly...

I agree, sheet wax is perfect for such an application.

If you need it thinner, what you can do is lay up a part in woven glass in one side of the mould. once cured demould and sand smooth the peel ply side to the exact finish you want.  Remount in the mould with a little filleting wax to seal the edge to stop resin running under (release coat EVERYTHING just to be sure!!) then take your second mould from it.
