Not being a chemist or owning a microscope, my guess is that the fibers from the dryer are much longer than flox and may "puff" up after you mix them with epoxy. If the epoxy has enough viscosity to damp down the puffiness, it might work fine. Take a look at real flox and you'll see what I mean.
Or, you could mix up a batch and layup a test panel. Who knows, you may have found the "undiscovered country"!
Test batch it is……..Might be pink, blue, or yellow. LOL.
Inquiring minds want to know. Keep us posted.
Love it when someone comes up with something new.:
Color is a plus!
Dryer lint rubbed with vasoline makes a great survival fire starter. Not what you asked about but just the same.
this is a fascinating thought. It may be that maybe epoxy might not bond to synthetic fibers, or that the shape of lint particles don't lend themselves to wetting out and you get dry spots that won't mix up, but I think the only way to determine would be to just give it a try.
