Thanks David,

That is a very handy link.

Looks like I need 12 of their standard Twill 2x2 sheets of CF (1.27m x 1m) to get approx 3mm tube thickness).

Just so happens my required CFC tube is 1.26m L x 0.315m OD . That's pretty convenient, pi * Do = 0.99m for my finished tube.

more questions :

a) I'll only need to trim about 10mm from each 1m sheet .... or would I be better off having a 10mm longitudinal overlap per "wet sheet" ?

b) how easy is it to cut unepoxyed CF sheet with a Stanley knife or sissors ?

c) Does the expoxy add anything to the thickness per sheet ? or it just a wetting / bonding agent that soaks the carbon fibres and adds nothing to the thickness per lay as such once rollered ?
