If only there were a YouTube video that could help you and save you all kinda of time / trouble...
Get that video - figure it out.

Bahahaha, if only there were a movies on the youtube showing the proprietary development of a particular fin manufactures methods, so any person can copy it and start their own fin business. Yeah...if only...
Theres is no doubt you have some nice equipment, or at least access to this all. However, i feel all of this might be complicating the issue. you need to get away from the plastic and the tape and pick up some epoxy and resin and start experimenting with all the different cf/ fiberglass mats you can find.
What is the final goal of this project? are you trying to manufacture fins so you can sell them, or are you just playing around with some free shop time at work?

The info is public (in the "free" world), not secret. He put it there and / or knew it was being recorded.
I have never made one, but I suspect that even IF you follow the video to a "T" that your fin may be mediocre at best. There's a lot of art involved and materials / adhesive specifics makes all the difference.
I'm suggesting that it'd be easier to start with a known / proven formula and tweak / adjust / modify from there.
Right now, he's not even in the right ballpark.
Monofins / hyperfins undergo tremendous forces. This bubblegum and tape method won't cut it!!
MUCH of the performance is in how the blade flexes - both in overall stiffness and in how the layers are peeled away and the design therein.
Then you've got footpocket strength / performance / flexing.
It ain't easy to copy. Even with the "recipe", It'll take 10-25 iterations to get something that performs better than a $40 rubber finis foil monofin.
And that's assuming the maker understands materials, their properties and can use a monofin well enough to be be able to translate what they feel / see into an iterative development process.
Right now, using tape to bond layers together doesn't seem to be headed in the right direction.

By trying new things, you are exposed to the likely outcome of failure. However, you are also exposed to the less likely outcome of success with innovative progress. Thanks for trying something new and sharing the results, even though it did not work out this time.
If you want to DIY with tried and true methods, you can use your metal cutting templates as razor-knife guides to trim and peel away layers of something like this: http://www.eplastics.com/NAME_80

co-cure = laminates are cured together with the binding matrix of the reinforcing material. So, you cut and lay fabric in your tapered design for the fin blade, then a matrix is applied, vacuum bagged and debulked and allowed to cure. The other method is to use pre-preg composites that have uncured matrix in the fabric already. It still needs to be vacuum bagged, and you will also need an oven to cure pre-pregs.
Negative.
Try these guys. They have everything you need to do composites right.
