Investigation of carbon/carbon composites produced by CVD/CVI method for biocompatibility

In this study , carbon/carbon composite structures were obtained by creating a pyrolytic carbon matrix around three-dimensional woven carbon fiber preforms using the Chemical Vapor Deposition-Infiltration (CVD-CVI) method. Subsequently, the produced C/C composites were divided into two groups, with one group being coated with SiC (silicon carbide) using the CVD method. Both coated and uncoated samples were examined separately. To determine the suitability of these materials for use as implants in living bodies, their biocompatibility was investigated through structural, thermal, mechanical, and cytotoxicity tests.
