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?

Of course there is. The resin uptake for soric is very well documented. Here the numbers out of my main supplier's catalogue, wich are within +-10% to my experiments:
Resin uptake in kg/m^2:
Sf2mm: 1
sf3mm: 1,3
lrc1,5mm: 0,6
lrc2mm: 0,8
lrc3mm: 1
from here the actual volumetric resin contend is just one simple calculation away. But I don't know why you want to know that, except to calculate the resin uptake.

oekmont, Thank you for your very useful information. I will use this data to calculate the cured weight of the items I will make as a part of my UAV monocoque. Naturally, I am trying to design the lightest possible layup. Once the design is set and the materials are all purchased, I will use this to calculate the amount of resin to prepare before starting a resin infusion.

When I asked the question, I was thinking that perhaps the resin uptake for soric is described in the same way that carbon fiber is described as a percentage. After reading your information, I realize that the manufacturers report this as resin uptake which for my needs is just as useful to plug into my calculations for the net total weight. And I did find similar values on the manufacturers websites for the materials I am considering.
Your help is very much appreciated.
