While making tubes sometimes I manage to archive 70-75%. But some articles say that for wet layout and vacuum bagging 60% is the best I can get.
My question is do I really get 72% or my calculations are wrong? For example dry CF weighs 231g, cured part 320g. So
100 / 320 * 231 = 72.2%
I use a quite thick UD 300g/m, no release film (only peel ply) and 2 layers of breather fabric.
