Carbon layer thickness: do you know it?

Hi guys, I hope somebody can help me.
I have to make a 27,2mm diameter tube, and to make this I'will wrap more times a single sheet of carbon around a 1" diameter tube (25,4mm). 
the tube will be used to be connected to the hull of a saddle I'm going to create.
My question is: does anybody know the thickness of a single layer of carbon?
In this way I will know the number of wrapping I have to do in order to reach the 27,2mm.
Consider that, after the wrapping, the created tube will be closed into the bag and used with the vacuum bagging, so that the carbon will be more compressed.
In the end I will give a layer of glossy finishing.

Thanks a lot for the help Wink

Thanks Warren, for your help. Yes, I can also consider this option Wink

If you are in effect, "roll wrapping" the fibre, albeit wet lay rather than pre-preg, you can use a Composites High Shrink Tape to consolidate the layers and squeeze out the excess resin.

It will also have the benefit of leaving a relatively smooth even outer finish with just small "ribs" from the tape edges that can be sanded out.
