PEEK vs PPA-CF results

Comments

Jose Angel Fernández

Surprising results? Or maybe not? After all, PEEK is a polymer with quite a few years under its belt (1978- https://en.wikipedia.org/wiki/Polyether_ether_ketone), despite its relatively limited use and extremely high cost. It’s expected that it might be outperformed by more modern blends of other materials. Perhaps a PEEK-CF blend could significantly surpass its initial performance. A different matter is the adhesion between layers, which is truly terrible. This aspect would need to be explored further because the data does not seem realistic.

Siraya PPA-CF is only $56/kg on Amazon in the US

Data is presented very well, as usual, but the upper right graph (“Deformation in the creep test” seems to have a pet peeve of mine, which is the Y axis not starting at 0. Might just be a LibreOffice error (I don’t have Excel). In any case, surprising findings! Great work!

You are doing very good job, this is only one patreon channel I will continue pay for future

Very interesting results. As you say, maybe the PEEK objects were not printed optimally by the provider. In any case, the PPA-CF is very impressive, though for us who are used to "pretty good" filaments for $30-$60/kg, at $200/kg (ie: $150 for a 0.75kg roll) it is a niche filament justifiable for only very unique use-cases -- eg: small prints that need to be particularly strong and/or heat-resistant, or for larger models that are otherwise difficult or impossible to manufacture without critical discontinuities. But it's still less expensive than PEEK!

Thanks 👍

Hi Igor --"but those who knows, where to search, they will find it already ;-)". Can you give us a hint? :^)

Jan Höhl

I second that, for some filaments at least.

We would really get much value if you added wear resistance in tests. Spevifically for these materials
