Description: The project was interested in developing a cage (for use in spine treatment) made of a carbon-carbon composite in two modes:
1. a cage composed of a bearing core made of titanium with the surfaces contacting the bone made of the C/C composites in order to ensure elastic linkage of two vertebral bodies resulting in good bonding with the bone.
2. after testing the first mode, a cage based only on the C/C composites was designed. It may be stated that the construction of the implant as a combination of a titanium cage with a biologically favorable C/C composites solves the problems with the strength of the core whereas its biological benefit remains preserved. On the basis of mechanical tests and simulation of the strain of the spinal segments it was found that as a self-supporting component the C/C composite is not a material sufficiently suitable for the construction of intervertebral implants from the mechanical point of view. |
