properties were designed to produce constructive bone remodeling. The component contained a core of unidirectional carbon- polysuIfonc composite enveloped with a bidirectional braided layer composed of carbon—polysulfone composite covering the core. These regions were encased in an outer coating of pure polysulfone (Fig. 8),

Finite-element stress analysis predicted that this construction would cause minima! disruption of the normal stresses in the mract cortical bone. Canine animal studies carried out to 4 years showed a favorable bone remodeling response. The authors suggested that implants fabricated from carbon— polysulfone composites should have the potential for use in load-bearing applications. An implant with appropriate elastic
