“…In a recent study, Campbell et al (2008) analysed the mechanical behaviour of composite femoral stems made of carbon fi bre reinforced nylon-12 (CF/PA12). Fatigue testing showed that the prosthesis survived two million load cycles under a maximum applied load of 5 kN.…”

“…The most common approach is to press-fi t the joint prosthesis into the bone using a grouting material called bone cement . From the 19.12 S-N compressive fatigue curves of CF/PA12 cylindrical tubes for femoral stems applications (Campbell et al, 2008). Over the past three decades or so, there have been a large number of reports on the impact of an assortment of variables on the fatigue lifetimes of a large number of acrylic bone-cement formulations, and the main results has been reviewed by Lewis (2003).…”

Fatigue fracture has been identifi ed as one of the major causes of implant failure of medical devices, and it represents a serious limitation for the intended usage of polymer composites for hard and soft tissue applications. This chapter presents an overview on the fatigue behaviour of polymeric composite biomaterials for bone repair and replacement, dental applications, joint replacement, spine surgery, tendons and ligaments augmentation devices and vascular grafts. Some recent advances in testing techniques are outlined and the future development of fatigue-resistant biocomposites is discussed.

“…The present study describes the factors that affect the fabrication of the composite femoral stems using the inflatable bladder molding process and the determination of the process window for this process. In a second communication [34], the mechanical strength and fatigue performance of the stems are evaluated to validate this novel THP design. In vitro biocompatibility and in vivo osteointegration work is reported elsewhere [35].…”

“…Furthermore, fibers are widely used for improving the mechanical performance of polymer composite nowadays [9–13], such as carbon, glass and aramid fibers. Carbon fibers (CF) have been widely used as reinforcements for ceramic, polymeric matrices in light of their excellent properties including light weight, high strength and modulus, good electrical conductivity and stability at elevated temperatures [14,15].…”

BackgroundIdeal bone repair material should be of good biocompatibility and high bioactivity. Besides, their mechanical properties should be equivalent to those of natural bone. The objective of this study was to fabricate a novel biocomposite suitable for load-bearing bone defect repair.Material/MethodsA novel biocomposite composed of carbon fiber, hydroxyapatite and polyamide46 (CF/HA/PA46) was fabricated, and its mechanical performances and preliminary cell responses were evaluated to explore its feasibility for load-bearing bone defect repair.ResultsThe resultant CF/HA/PA46 biocomposite showed a bending strength of 159–223 MPa, a tensile strength of 127–199 MPa and a tensile modulus of 7.7–10.8 GPa, when the CF content was 5–20% (mass fraction) in biocomposite. The MG63 cells, showing an osteogenic phenotype, were well adhered and spread on the surface of the CF/HA/PA46 biocomposite. Moreover, the cells vitality and differentiation on the CF/HA/PA46 biocomposite surface were obviously increased during the culture time and there was no significant difference between the CF/HA/PA46 biocomposite and HA/PA (as control) at all the experimental time (P>0.05).ConclusionsThe addition of CF into HA/PA46 composite manifest improved the mechanical performances and showed favorable effects on biocompatibility of MG63 cells. The obtained biocomposite has high potential for bone repair in load-bearing sites.
