Characterization and biological behavior of a carbon fiber/carbon composite scaffold with a porous surface for bone tissue reconstruction

A carbon/carbon composite scaffold for bone tissue reconstruction was prepared. The surface morphology and trace elements of the scaffold were analyzed and its biological behavior was studied both in vitro and in vivo. It was found that the scaffold had a good biocompatibility, not only resulting from its high purity and mild cell toxicity, but also from the excellent integration of the bone tissue with the composite scaffold during the reconstruction.
