We all know the desired ratios of CF to resin and we know the achievable ratios differ between hand layup/vacuum bagging, and Resin Infusion... but what is the ideal and actually achievable ratio for Soric/Resin when done as part of a Resin Infusion that has CF skins? Are there any good published data for Soric/Resin design ratios?

Oakemont, we actually got a quite a variety of resin uptake figures for soric in our own testing and calculating from customers figures - with the manufacturers quoted figure being fairly conservative in our experience. Especially as a lot of people making cosmetic parts will leave the resin feed open for longer than usual to help avoid pinholes.  Of course making it resin rich in this way effects the fibre/resin ratio as well as the resin uptake.  An accurate and fair comparison would only work exactly on a like for like basis. I imagine Lantor's test figures will be for a standard infusion done a set way hence being towards the lower end of the resin uptake we have seen.
