Hey, I got some interesting news from a few ex FSAE mates, apparently Boeing and some other aircraft manufacturer are buying up the worlds supply of carbon fibre. The new planes have a ship load of carbon in them. So all the smaller suppliers (eg CG composites) are having a lot of trouble getting anything and prices are skyrocketing. I used to buy plain weave, 120g/m2 (I think???) carbon for $26/m now we are talking over $50/m.
So all of a sudden carbon work is looking very expensive again.
As someone said, use epoxy based resin, no point using poly resin with carbon, might as well use fibreglass if you skimp on the resin.
The other thing I found is that generally carbon is easier to use than fibreglass (depends on type of weave though) because carbon more easily moulds around corners.
yug_r34, yes I would be interested in working on CF tail shafts, that is something I did not actually think of branching into. I'll send a PM.
