Thermomechanical investigations of PEKK-HAp-CS composites

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2019
In this experimental study, a composite of poly-ether-ketone-ketone by reinforcement of hydroxyapatite and chitosan has been prepared for possible applications as orthopaedic scaffolds. Initially, different weight percentages of hydroxyapatite and chitosan were reinforced in the poly-ether-ketone-ketone matrix and tested for melt flow index in order to

Microporous Coatings of PEKK/SN Composites Integration with PEKK Exhibiting Antibacterial and Osteogenic Activity, and Promotion of Osseointegration for Bone Substitutes

ACS Biomaterials Science & Engineering, 2019
To improve the antibacterial and osteogenic activities of poly(etherketoneketone) (PEKK), concentrated sulfuric acid (H2SO4) suspension with silicon nitride (SN) microparticle was utilized to modify PEKK surface. Through sulfonation reaction, microporous coatings of PEKK/SN composites were created on PEKK surface, which were integrated with PEKK ...

High‐temperature steam‐treatment of PBI, PEKK, and a PEKK‐PBI Blend: A solid‐state NMR and IR spectroscopic study

Journal of Applied Polymer Science, 2012
AbstractBlends of polyaryletherketones (PAEK) with polybenzimidazole (PBI) are of commercial interest due to their improved upper service temperatures and wear properties when compared with the PAEK analogs examined to date. The retention of properties of the PBI component generally thought to be disadvantageous in more thermally or chemically ...

PEEK-PEKK en de PEAK-familie

Tandartspraktijk, 2016
Sinds 1980 wordt PEEK in de orthopedie en de traumatologie gebruikt voor onder andere kunstheupen en als transplantaat bij botdefecten. Sinds de opmars van cad/cam-toepassingen in de tandheelkunde is dit lichte maar sterke materiaal ook toepasbaar in de tandheelkunde. Op de IDS-beurs van 2014 in Keulen liet een fabrikant als Cendres+Metaux toepassingen

Fiber/Matrix Adhesion in Graphite/PEKK Composites

Journal of Thermoplastic Composite Materials, 1992
Experiments with poly ether ketone ketone (PEKK) resin and AS-4, IM-7, and G30-500 fibers showed excellent correlation between resin/fiber contact angle and composite transverse flexural strength as measures of resin/fiber interfacial strength. Both tests indicate the strongest interface for G30-500/PEKK followed by IM-7/PEKK and AS-4/PEKK.

Interaction du PEKK et des composites PEKK/FC avec l'eau et le Skydrol

Alléger les avions reste une problématique majeure pour l’industrie aéronautique. Le développement de composites à matrices thermoplastiques, en remplacement des thermodurcissables, permet d’obtenir des matériaux soudables et recyclables, avec une température de service supérieure.
