Carbon-carbon composite material artificial skeleton
The invention discloses a carbon-carbon composite material artificial skeleton, and relates to the technical field of medical supply materials. The invention is applied to the field of artificial skeleton materials in human bodies or animal bodies. The artificial skeleton material comprises a carbon fiber preform, pyrolytic graphite or pyrolytic carbon and a surface coating layer; the surface coating layer adopts one of a hydroxyapatite layer, a pearl layer and high-strength mineralized hydrogel, and the surface coating method comprises dipping, in-situ growth or spraying; filling of pyrolytic graphite or pyrolytic carbon specifically adopts a vapor deposition or impregnation sintering process; and the manufacturing process comprises the steps of manufacturing a carbon fiber preform, filling and densifying, forming a blank through precision machining, and obtaining the artificial skeleton in a surface coating mode. Compared with stainless steel and titanium alloy metal, the artificial skeleton has the advantages of being lighter in mass and smaller in density, the specific density can be designed according to different parts, the structural density and strength requirements of different parts are met, good biocompatibility is achieved, and anisotropy and strength can be designed according to an actual prefabricated body.
