#2I find the Epoxy substitute very interesting - I feel like there could be a lot of uses for an epoxy strong enough to work in Carbon Fiber applications but can be removed with a chemical process at room temperature. Re-enterable potting compound? Fixturing material for machining?

Cured polyester resin as used in fiberglass reinforced plastic is soluble at room temperature using solvents like MEK or Acetone...

#4This may make it so carbon fiber items could be repaired as the epoxy can be removed and reapplied.
Being able to repair goods is much better for the environment than being able to recycle them.

#5FWIU flax and hemp are more sustainable and potential substitutes for carbon fiber, which is industrially hazardous to produce?
The branching structure makes e.g. hemp bast fiber ideal for supercapacitor (~battery) anodes. How does this plant-based epoxy affect conductivity and resistivity in various materials in various outdoor conditions with and without a coating?
If it's plant-based, is it safe next to plenum cable? Can it be used for Hemp structural framing lumber, such as HempWood?

A lot of composite artifacts are fairly easy to repair already, assuming you accept some degradation of performance since the newly bonded media and resin won't be chemically attached, but mechanically instead.

#7Hope this starts with checked
Fiberglass too; boat hulls also fill up landfills

I hope so too. I was thinking of printed circuit boards.

My experience with carbon fiber is mostly in cycling.
One of the drawbacks with carbon fiber is its tendency to fail catastrophically.
By that I don't mean that it tends to fail per se, but when it does it often doesn't do so gradually with warning like steel or aluminum (which warps, dents, and/or cracks visibly). So there's a certain fear about hidden cracks and failure points.
This gets exacerbated when talking about used items.
When talking about recycling or repairing carbon fiber, then, I think you'd have to convince people that it's just as stable as the original product, and that there aren't any hidden failure points. This obviously wouldn't apply to everything carbon fiber, but for things where it's often used, like in transportation, I think you'd have to have an inexpensive, foolproof, airtight way to verify integrity.

#10how durable would this stuff be? good enough for wind mills?
