“…These basic studies established that the friction and wear behavior of PEEK depended not only upon the type and amount of fiber reinforcement, but also the surface roughness of the PEEK surface and the counterface, as well as temperature, sliding speed, and contact pressure. Although an extensive body of tribological literature exists for PEEK and its composites, when we restrict ourselves to conditions relevant to total joint replacement applications, only a limited number of investigations have been reported in the peer-reviewed literature [17,[176][177][178][179].…”

“…Total Hip and Knee Replacement-Starting in the 1990s, carbon-fiber reinforced PEEK (CFR-PEEK) composites were evaluated as candidate bearing materials for hip and knee replacement [17,176] and were compared with UHMWPE, which has been used for these applications since 1962 [180]. During the 1990s, gamma sterilized UHMWPE was the polymeric material of choice for total joint replacements.…”

“…The biotribology of PEEK was first reported by researchers from Howmedica (Rutherford, NJ), who were aware of not only the previous industrial wear testing of composite PEEK, but also the poor clinical performance of Poly II [176]. Hip cups for wear testing were initially produced by injection molding 30% discontinuous, pitch carbon fiber (Amoco, Grade VMX-12) reinforced 150G PEEK resin.…”

Since the 1980s, polyaryletherketones (PAEKs) have been increasingly employed as biomaterials for trauma, orthopedic, and spinal implants. We have synthesized the extensive polymer science literature as it relates to structure, mechanical properties, and chemical resistance of PAEK biomaterials. With this foundation, one can more readily appreciate why this family of polymers will be inherently strong, inert, and biocompatible. Due to its relative inertness, PEEK biomaterials are an attractive platform upon which to develop novel bioactive materials, and some steps have already been taken in that direction, with the blending of HA and TCP into sintered PEEK. However, to date, blended HA-PEEK composites have involved a trade-off in mechanical properties in exchange for their increased bioactivity. PEEK has had the greatest clinical impact in the field of spine implant design, and PEEK is now broadly accepted as a radiolucent alternative to metallic biomaterials in the spine community. For mature fields, such as total joint replacements and fracture fixation implants, radiolucency is an attractive but not necessarily critical material feature.

“…The term hybrid composite denotes the incorporation of two or more different types of fibers in a common resin matrix. In other words hybrid composites are composed of two or more different types of reinforcements which have different mechanical/physical and/or other properties leading to hybrid effect [1][2][3]. This type of composite architecture allows researchers to design a composite with tailored properties in demanding applications.…”

“…The hybrid effect is also important in the wear behavior. Several studies were conducted on wear behavior of composites, including carbon reinforced composites [2,5,6] and Kevlar reinforced composites [7]. However there is no information regarding the wear behavior of hybrid reinforced composites in the public domain.…”

The aim of this study is to investigate the effect of hybridization of fabrics on wear properties of epoxy composites and to relate them to impact properties. With this aim carbon/glass/Kevlar fabrics were hybridized to reinforce epoxy composites. Epoxy composites reinforced with only carbon, glass or Kevlar fabrics were also prepared as reference composites. The wear tests were carried out using a pin-on-disk device. The wear surfaces of composite specimens were examined by scanning electron microscopy to investigate the different behavior of three distinct fabrics in the hybrid composites. The results have shown that carbon fabric reinforced epoxy composite exhibited the highest wear resistance, whereas the wear resistance of Kevlar fabric reinforced epoxy composite was the lowest. As expected, the wear resistance of hybrid composites was lower than that of only carbon fabric reinforced composites.

The combination of different materials in an implant gives the opportunity to better fulfill the requirements that are needed to improve the healing process. However, using different materials increases the risk of galvanic coupling corrosion. In this study, coupling effects of gold-anodized titanium, stainless steel for biomedical applications, carbon fiber reinforced polyetheretherketone (CFRP), and CFRP containing tantalum fibers are investigated electrochemically and by long-term immersion experiments in simulated body fluid (SBF). Potentiodynamic polarization experiments (i/E curves) and electrochemical impedance spectroscopy (EIS) of the separated materials showed a passive behavior of the metallic samples. Anodized titanium showed no corrosion attacks, whereas stainless steel is highly susceptibility for localized corrosion. On the other side, an active dissolution behavior of both of the CFRPs in the given environment could be determined, leading to delaminating of the carbon fibers from the matrix. Long-term immersion experiments were carried out using a set-up especially developed to simulate coupling conditions of a point contact fixator system (PC-Fix) in a biological environment. Electrochemical data were acquired in situ during the whole immersion time. The results of the immersion experiments correlate with the findings of the electrochemical investigation. Localized corrosion attacks were found on stainless steel, whereas anodized titanium showed no corrosion attacks. No significant differences between the two CFRP types could be found. Galvanic coupling corrosion in combination with crevice conditions and possible corrosion mechanisms are discussed.
