Counterface topographical effects on the wear of polyetheretherketone and a polyetheretherketone-carbon fiber composite

Wear, 1991
The unlubricated sliding wear behavior of non-reinforced polyetheretherketone (PEEK) and a PEEK-carbon fiber (PEEK-Cf) composite was investigated under lightly loaded conditions against mild steel counterfaces. The results showed the occurrence of a relative minimum in wear for the non-reinforced PEEK-mild steel system, resulting from interfacial film ...

Titanium and hydroxyapatite coating of polyetheretherketone and carbon fiber‐reinforced polyetheretherketone: A pilot study in sheep

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2015
AbstractPurpose: The purpose of this study was to evaluate the bone formation capability of polyetheretherketone (PEEK) and carbon fiber‐reinforced PEEK (CFR‐PEEK) implants coated with different titanium and hydroxyapatite plasma‐sprayed layers after 2 and 12 weeks. Methods: In six sheep 108 implants were placed in the pelvis.

Anisotropy in polyetheretherketone films

Journal of Nanophotonics, 2012
Optical measurements reveal the preferential orientation of nanostructures within polymer films, which results from the fabrication process including mechanical and thermal treatments. As the wavelength of the incident light is generally much larger than the characteristic dimensions of the molecular arrangement in semi-crystalline or amorphous ...

Preparation and tribological properties of polyetheretherketone composites

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2010
AbstractPolyetheretherketone (PEEK) is a thermoplastic engineering plastic with excellent mechanical properties. In this article, PEEK and its composites filled with ultrahigh‐molecular‐weight polyethylene (UHMWPE) were prepared by vacuum hot‐pressing method.

Triple-functional polyetheretherketone surface with enhanced bacteriostasis and anti-inflammatory and osseointegrative properties for implant application.

Biomaterials, 2019
Polyetheretherketone (PEEK) is considered a potential orthopedic/dental material because of its excellent mechanical and chemical properties (e.g., similar elastic modulus to that of human bone). However, the poor bacteriostasis and anti-inflammatory and
