Physical aging characteristics of polyether ether ketone

Composites Science and Technology, 1987
Abstract 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, 2023
Microscale 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.

Synthesis and Research of Properties of Polyether Ether Ketone

Key Engineering Materials, 2019
Polyether ether ketones based on 4,4'-difluorobenzophenone and hydroquinone in sulfolane medium in the presence of anhydrous potassium carbonate were synthesized by the method of high-temperature polycondensation. The rheological, thermal, electrical and physical-mechanical properties are investigated.

High field properties of polyether-ether-ketone

[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
The mechanism of electrical conduction in PEEK (polyether-ether-ketone) was studied from the results of DC conduction and thermal pulse current (TPC) measurements. The DC conduction current in PEEK films was measured at various electric fields at room temperature.

The response of polyether ether ketone to one-dimensional shock loading

Journal of Physics D: Applied Physics, 2004
The behaviour of the polymer polyether ether ketone (PEEK) has been investigated under conditions of one-dimensional shock loading. This has involved measurement of the Hugoniot in terms of stress, shock velocity and particle velocity, and measurements of the lateral stress, which have been used to determine the shear strength, and its variation with ...

Blends of a liquid crystalline polymer with polyether ether ketone

Polymer Engineering & Science, 1992
AbstractBlends of Polyether ether ketone (PEEK) and a thermotropic liquid crystalline Polymer (LCP) based on paraoxy‐benzoyl and oxy‐biphenylene terepthaloyl units were prepared using a static mixer attached to a single screw extruder at 420°C. Rheological studies indicated an increase in the viscosity of the blends upon the addition of LCP.

Thermal Expansion of Polyether Ether Ketone Bearing Components

Journal of the American Helicopter Society, 2019
Carbon fiber–reinforced polyether ether ketone (PEEK) is a strong candidate for aerospace bearing cages due to its low density and good mechanical properties. However, there are still concerns regarding its performance at the elevated temperatures seen in aerospace applications.

3D printing of polyether-ether-ketone for biomedical applications

European Polymer Journal, 2019
Abstract Despite the rapid progress of several three-dimensional (3D) printing technologies, there exists a critical barrier in-term of processability of high performance materials. Polyether-ether-ketone (PEEK) is known for its higher mechanical properties, chemical stability, biological stability and biocompatibility suitable for certain biomedical
