Research on the Fused Deposition Modeling of Polyether Ether Ketone [PDF]

Polymers, 2021
As a special engineering polymer, polyether ether ketone (PEEK) has been used widely due to its excellent mechanical properties, high thermal stability, and chemical resistance. Fused deposition modeling (FDM) is a promising process for fabricating PEEK parts.

Modification of polyether ether ketone for the repairing of bone defects

Biomedical Materials, 2022
Abstract 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).

Taylor impact of polyether ether ketone

International Journal of Impact Engineering, 2006
Right 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.

Tribological behavior of blends of polyether ether ketone and polyether imide

Wear, 1993
Abstract In this study polyether ether ketone (PEEK) and polyether imide (PEI) were blended to raise the glass transition temperature (Tg) above that of PEEK while retaining the low-wear characteristics of PEEK. The friction and wear of injection-molded blends were measured in dry sliding by a stainless steel ball sliding on a polymer blend disk. The

Polyether Ether Ketone Cranioplasties Are Permeable to Diagnostic Ultrasound

World Neurosurgery, 2018
It 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, 2003
The 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, 2008
This 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.
