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.

You need to put keys on the flange to lock the pieces together. 

That's ok, so I will use the ratio 50/50, even considering that into the bag, the layers of peelply and other fabrics will absorb the resin in excess.

Then, I will check the diameter before to apply the final layer of finishing, maybe I won't need of it if the diameter is good enough

If the outer diameter is important, then why not look at making a female mould out of some pipe in 2 halves with bolted together flanges and using an inflatable bladder on the internal diameter. You'd have to "make" a pipe with the correct internal diameter though but it would give you good surface finish and a more accurate dimension. Bare in mind I haven't done this before but I'm sure the experts will chime in.Good luck regardless of your approach. 

That is assuming a good resin ratio though. Are you doing it wet lay? It's a bit harder to judge the thickness with wet lay because it's harder to hit your required resin/fabric ratio. Pre-preg or infusion you can nail a 60/40 ratio and get very accurate thicknesses. Wet lay you are probably looking at a 50/50 ratio if you measure correctly and can get the lay up right, so it could end up a bit thicker. 

Depends on the weight of fabric you are using. If you're using regular 200g fabric, then each layer is approximately 0.25mm when consolidated under vacuum.
