its depends entirely what kind of accuracies you are looking at 

There is no such data on the manufacturers information we have on our roll wrapped tubes.

To be frank, you will unlikely find that data freely available either as its a very specific application so the manufacturer is extremely unlikely to have bothered to measure those figures.

The Tubes do use a Toray T700 fibre so you may be able to find some data out there for the raw fibre and interpolate/calculate from there.

Any recommendations? Preferably available in 8mm OD tube of 2m lengths?
Been googleing but little doing.

A roll wrapped tube will suffer volumetric changes depending on how it's played up

I'm looking to use a CF tube for a length critical application with absolute minimum axial thermal expansion, would pultruded or roll-wrapped be better for this application?
If there is any data regarding the thermal properties of each to compare the two types that'd be brilliant.
