Taylor impact of polyether ether ketone
International Journal of Impact Engineering, 2006Right cylinders of the thermoplastic polyether ether ketone have been impacted onto a hardened steel anvil at velocities from 152 to 408 m s−1. The resultant deformation showed the expected ‘mushrooming’ behaviour up to impact velocities of 303 m s−1, before the impact face began to fracture.

Modification of polyether ether ketone for the repairing of bone defects
Biomedical Materials, 2022Abstract Bone damage as a consequence of disease or trauma is a common global occurrence. For bone damage treatment—bone implant materials are necessary across three classifications of surgical intervention (i.e. fixation, repair, and replacement).

Polyether Ether Ketone Cranioplasties Are Permeable to Diagnostic Ultrasound
World Neurosurgery, 2018It is a common assumption that the human skull and solid skull implants are impermeable to diagnostic ultrasound. We demonstrated in 2 patients that frontoparietal polyetheretherketone cranioplasties allowed useful imaging of intracranial parenchymal and vascular structures with higher ultrasound frequencies than the 2 MHz used for the temporal bone ...

Conduction current in polyether-ether-ketone
[Proceedings] 1992 Annual Report: Conference on Electrical Insulation and Dielectric Phenomena, 2003The mechanism of electrical conduction in polyether-ether-ketone is studied based on the results of DC conduction and thermal pulse current (TPC) measurements. Charging current curves as a function of time at 150 degrees C are shown along with similar curves at an electric field strength of 0.6 MV/cm.

Polyether ether ketone microstructures for chemical analytics
Microsystem Technologies, 2008This paper presents an initial approach towards polyether ether ketone (PEEK) microfluidic structures for chemical analysis by introducing PEEK capillary electrophoresis (CE) chips. PEEK shows outstanding material features, such as extremely high chemical resistance and mechanical stability, high temperature resistance, very low adsorption.

Physical aging characteristics of polyether ether ketone
Composites Science and Technology, 1987Abstract Creep studies and differential scanning calorimetry (DSC) indicate that physical (thermal) aging affects viscoelastic properties of polyether ether ketone (PEEK) at all achievable levels of crystallinity. The phenomenon has been observed over a range of crystallinity (2%–33% by volume) at several test temperatures.

Study on the chip shape for micromilling of Polyether-Ether-Ketone
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2023Microscale parts made of Polyether-Ether-Ketone (PEEK) are widely used in biomedical, aerospace, and manufacturing industries. The formation mechanism of the chip and machining quality of PEEK are closely related during the micromilling process. However, they have not been sufficiently studied yet.
