A 2:1 fibre:resin ratio and perfect surface finish with wet-lay vac bagging? That would be 66% fibre and 33% resin. Given most OOA pre-pregs are around the 40% resin mark, as is resin infusion, I am somewhat dubious - however if that is the case, I think you have made a mistake by switching to pre-preg!

No, 2 to 1, so for every 2gms of fibre there is 1 gm of resin or 100gms of fibre and 50gms of resin, so the percentage of resin to fibre is 50%.

I have weighed cloth before and after and my 'best' is a 51% increase in weight.

Sorry Steve, long day yesterday - I thought you meant combined weight of the finished component rather than individual weights of the reinforcement and resin. Carry on!
