Wear of ceramic-on-carbon fibre reinforced PEEK hip replacements
Total hip replacement has been a successful surgical intervention for many years. However, concerns regarding UHMWPE wear particle induced osteolysis [1], have led to alternative bearing materials to be sought. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) is a fibre-reinforced polymer which has shown reduced wear in hip and knee configurations compared with conventional polyethyle...
متن کاملFriction and Wear Performance of Glass Fiber Reinforced Poly-Ether-Ether-Ketone Composite against Different Polymer Counterparts
In tribological applications, because of the corrosive problems of the metals in water applications, poly-ether-ether-ketone (PEEK) and its composites are preferred for rubbing materials. As it is known PEEK is a high performance semi-crystalline thermoplastic polymer and has received significant attention in recent years. This is due to its high mechanical strength and elastic modulus, high to...
متن کاملQuality of Kiwifruit Juice Clarifed by Modifed Poly(Ether Ether Ketone) Hollow Fiber Membranes
Poly(ether ether ketone) with cardo group-based (PEEK-WC) membranes, in hollow fber (HF) confguration, were prepared via the dry-wet spinning technique through the phase inversion process and used to clarify kiwifruit juice. The depectinised juice was processed according to a batch concentration confguration in selected operating conditions (transmembrane pressure, 1.6 ...
متن کاملComparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study
STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
متن کاملWear and Wear Debris Generated from Ceramic-on-Carbon Fibre Reinforced PEEK Hip Replacements
INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...
