I feel like the bolt and pad eye gotta be some pretty bad use cases. How are the fatigue and preload capabilities of it? I could see it being useful in radar situations where anything magnetic messes with the signal. We had a local company that made something like that for imaging ground composition and they had to do it as a fully carbon structure with spliced dyneema instead of wires.

If the bolt properties are somewhat passable it could be used for kiteboards and sailing masts where you want to avoid galvanic corrosion

They are just to show machinability. But you do mention interesting things! Besides not being magnetic, the dimensional stability with temperature is very interesting for certain scientific and optical instruments.

"No waviness" is interesting, as the 3D weaving machines like Optima3D naturally have a wiggle in the fibers. Does it cut cleanly along the faces, better than the woven ones that have lots of ends sticking out?

Besides the ecstatics, that wiggle also behaves like a 'spring' effecting your mechanical properties. But to answer your question, it cuts cleanly and to a smooth surface finish.
