I thought it might be worth while to experiment with carbon fiber shielding of power cords.
I am concerned about fibers coming loose and want to find a resin that would bond the fibers and still be flexible enough for use as a power cord.
Has anyone tried this before or have any thoughts and ideas?

I figured that this would have the least dielectric effect on the conductors.
I was thinking of the benefit of RF shielding and absorption of RF entering and emitting from the cable.
Any thoughts on this?
TIA

You can set up an experiment.
First, do only the terminations.
Then, the middle.
Later add sections at the midpoint of each gap until you have covered the whole cable with CF.
This allows you to test how much and where CF makes a positive difference.
Then play with spacing. Take a look at the typical spacing of another known damping device, the Power Wrap. Copy that for starters with your cotton filler.
If you have the patience, it's a cheap experiment.

It may be of interest to ponder the notion of carbon fiber as it relates to carbon loading; how semiconductive carbon loading can affect dielectric energy storage and dielectric energy discharge; keeping in mind how the dielectric constant of various dielectric materials can affect the sonic signature of cables/wires/capacitors, et al.
Keeping in mind that in so many cases there's often a trade-off/compromise of designs within this hobby. The audiophile Holy Grail of "straight wire with gain" is a rather noble, almost Utopian notion of idealized perfection. However, in pragmatic practice, it's often a matter of what design/technology wins the (everlasting?) audiophile struggle of sins of commission vs. sins of ommission.
It’s often what a device does not do rather than what it does do that wins the race ;-)
just my eccentric 2 coins worth...

you are going to need to use a silicone based product. Typical epoxy used with CF dries hard.
I played around with CF a lot and in the end prefered cables w/o it. It tended to suck the life out of the music.
You can't just damp the entire cable with it in a tight jacket. You can best damp the terminations, right behind them, and the middle, but a whole cable may not be advised. There is also some issue about the distance between the damping compound (CF) and the conductors, I'm told, but have no further information on that. Sleeves surrounding the terminations and immediately behind them work well on PCs in my system. Have not gone onto speaker cables or ICs as yet.
I tried all sorts of permutations and ended up prefering none at all with my cables but as with anything in this hobby, it was my preference not a wrong/right.
1) Use acrylic painter's medium (gloss or matt), as this dries with some flexibility and will be waterproof etc. Not bad as a dielectric too. (As a less desirable dielectric substitute, PVC electrician's tape material can be bought as a liquid you can apply to the CF sleeve; available at home depot.)
2) Use that or regular epoxy resin on ONLY the ends, as that's what would unravel, not the middle. This would be my choice.
CF is not a problem like fiberglass, IMO. It doesn't "splinter" or release fibers just from general use. It's more dangerous when in a hard medium like resin and then working with that that it splinters if cut or sanded. By itself, it's just the consistency of any thick cloth.
Do get the bi-directional sleeve type, not uni-directional. Solar composites sells this cheaply enough to play with in whatever length you want.
you could try plasticoat it is either a paint like product that give a rubbery coating to things like tool handles. Or it comes as a spray can like spray paint its pretty much the same but would take a lot more coats to build up any thicknees. If that is what you want.
Why you would want it at all is beyond me but there you go a flexable coating you could apply to CF mat.
