Resin infusion and resin content
Resin infusion and resin content
(OP)
Hi everybody!
I know that it's possible to achieve a very low resin content when using resin infusion. In fact, someone once told me that he would have a hard time getting a higher resin content than 40% when using infusion.
My question is this: Is this low resin content regardless of the type of reinforcement? Will CSM and UD have the same low content?
You might ask "Who would use resin infusion when working with CSM?" My answer: "Boatbuilders!"
If you have any typical numbers, please share!
Best regards,
Søren Flening

Ideally, I would like some numbers for the resin (or fiber) content of CSM, WR and UD when using resin infusion. It's only for preliminary design work, so they don't have to be 100% exact - typical numbers will do.

If the mold is "tall" when the resin is introduced there is the static fluid height pressureization effect that should be considered ie. the vacuum pressure at the bottom of the filled bag will be less than at the top resulting in a higher resin percentage at the bottom.
pressure from static head at the bottom
= specific weight X height
If s.g. =0.8 (good first assumption)
then = 0.8(specific weight of h2o)x height
= 0.8(9810kN/m^3)x height in meters

FV can and is "tailored" with the use of rigid/semirigid IML tools thereby controlling the infusible volume... the volume can be controlled modified with a vacumm sealing chambers on removable "hard" stops. You are only limited by budget and imagination.
