Determination of Crystallization Kinetics of Polyetheretherketone in Material Extrusion Process Using Numerical Simulation

Polymers for Advanced Technologies, Volume 36, Issue 12, December 2025.
ABSTRACT Despite considerable progress over the past 3 years, some issues remain in obtaining printed polyetheretherketone (PEEK) parts printed by the material extrusion process (MEX). The fast crystallization of PEEK during printing results in distortion, poor dimensional accuracy, and low inter‐filament adhesion.

Fabrication of the polyetherketoneketone-reinforced nano-hydroxyapatite composites as inspired by the cortical bone

Supramolecular Materials
Cortical bone has superior mechanical performance. Hydroxyapatite (HA) as its main component are attractive bioactive materials, but possess weak strength. The critical factor is the difference in the structure.

Carbon Fiber‐Reinforced Silicon Carbide (C/C‐SiC) Fabrication Derived From Polyetherketoneketone (PEKK) as an Alternative Thermoplastic Carbon Precursor

Journal of Polymer Science, Volume 63, Issue 21, Page 4587-4599, 1 November 2025.
ABSTRACT This study shows the first successful fabrication of a carbon fiber‐reinforced silicon carbide (C/C‐SiC) via the liquid silicon infiltration process using two thermoplastic polyetherketoneketone (PEKK) powders as carbon precursors. Samples are analyzed after each processing step and compared to polyetheretherketone (PEEK)‐derived reference ...
