i plan on making a Roll Wrapped carbon fiber tube of 90mm ID and 97mm OD.I was planing on using 12k 400gsm plain weave Carbon fiber material for the same but i am concerned that the cloth will not conform well to the mandrel at the time of wrapping.I plan to vacuum bag after wrapping it manually .

You have to be able to brake the initial key that is formed by the curing process, i tried freezing it, heating it and smashing with a block NO JOY but vaseline gave no problems.
