Hey guys,

So i tried my first prepreg carbon mould. I used an 8inch ID piece of steel tube and laid up the sheets on the inner surface.

Basically what i discovered was a very effective way to adhere carbon fibre to a steel tube. I just used some silicone mould release i had lying around and think this might be the problem.

Anyway, basically what im wondering is what would be the best way to make large 8 inch (and larger) cylinders from prepreg?

Thanks.
