Prusa PPCF is an interesting filament
Started printing stuff with it (mostly small racks to hold chemical reagents and solvents) since it's highly chem resistant. Interesting material. It prints easily, is strong and is very light weight with a nice matte finish. It also has a "soapy" feel to it. Kind of like it. The only downside is that it's somewhat expensive. Since it has a very low density and high temp resistance I can imagine this is a good choice for model rockets as well.

The one downside is the filament is quite stiff and has a tendency to jump off the spool if not careful.

Update. This stuff has weak interlayer adhesion even printed with an 0.6mm nozzle and 0.3mm layer height. I’ve had to anneal the parts otherwise it snaps easily (worse than PLA even). I’m repurposing my reflow oven for this.
RE: Prusa PPCF is an interesting filament
I watched a video recently (I think it was My Tech Fun) where he saw layer adhesion improve dramatically with PC-CF by disabling the part cooling fan. Obviously for some parts this isn't possible due to their geometry, but might be worth considering.

I saw the same. I've been annealing at 140C. Alternatively, I'll give this a try as an experiment.
