DIY Carbon Fiber Freediving Fins by Vacuum Infusion Build

I've always been interested in building my own gear and composites are one area that I had very little experience with. So I took the time to research the Vacuum Infusion process for Carbon Fiber so take a look at my first go! Of course if you can think of some improvements please comment below. If you want any more description on the process also comment.

Ended up modeling a few builds that I saw on YouTube and modeling them on ANSYS ACP PRE/POST student addition (another big learning curve) and coming up with a 20N force at a 90 degree bend metric that was the target for a mid flex medium stiffness blade at 29 degree angle. I can make a video on that whole process if you would like. May do some fluid modeling of a flexible foil on ANSYS if I get really ambitious.
