I wonder about a co-extruded fluoropolymer-with-kevlar-or-glass filament
that would be usable in a 3d printer type arrangement. Finished-part
properties may suck, of course. Just idle speculation.

So the "glass-fluoropolymer composite" that Doug refers to here is the same
stuff as the mysterious "nonburnite" that you've mentioned previously?
From the little I know about the practical characteristics of
fluoropolymers, it
sounds like making anything like a "classical" fabric-and-binder composite
structure with them must take some unusual methods!
The methods could be unusual, but that by itself doesn't necessarily imply
the methods would be difficult/dangerous/onerous.
To me, if you can get fluoroplastics that are meltable and extrudable (of
which there are quite a few), then what's stopping you from melting some of
the fluoroplastic into the fibre? Then you lay up in a conventional method,
autoclave (probably at high temperatures than traditional) and voilà.
Or if you were laying up mat - layer or fibre mat, layer (or 2 or 3) of
fluoropolymer film, layer or fibre mat ... etc autoclave and voilà.
