PEEK vs PPA-CF results
Added 2024-12-30 09:20:53 +0000 UTCFirst of all, thank you all for Your support, without You, this channel would be placed in a stand-by position, You are the real driving force for the MyTechFun.
Have a pleasant Holidays and I wish you all Happy New Year.
PEEK vs PPA-CF video is finished (working on description and subtitles, it will be public in few hours, but those who knows, where to search, they will find it already ;-) . The results are not available for the public, but you can download the Excel file from this post.
Other: in January (only filament testing is listed):
Qidi PET-CF vs PET-GF (arrived today).
Siraya PAHT-CF 3× (regular, CF and CF Core), filaments are here.
BambuLab BLACK ABS, ASA, ABS-GF and ASA-CF in one video (request from viewers, since they are tested separately, but in different colors)
3DO PC vs PC-CF
Phaetus Nylon

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.

2024-12-31 18:20:18 +0000 UTCData 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!

2024-12-30 13:30:08 +0000 UTCVery 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!

2024-12-30 10:32:53 +0000 UTCI second that, for some filaments at least.

2024-12-30 10:18:39 +0000 UTCWe would really get much value if you added wear resistance in tests. Spevifically for these materials
