Carbon fiber composite artificial bone and preparation method thereof

A carbon fiber composite artificial bone, comprising a carbon fiber composite spring-like frame and a carbon fiber composite plate dowel, wherein the carbon fiber composite plate dowel penetrates through a cavity of the carbon fiber composite spring-like frame,

• wherein the carbon fiber composite spring-like frame comprises a carbon fiber spring-like frame and a pyrolytic carbon coating, a silicon carbide coating or a pyrolytic carbon/silicon carbide mixed coating on a surface of the carbon fiber spring-like frame, and the carbon fiber spring-like frame is of a spring-like structure woven from carbon fibers,
• wherein the carbon fiber spring-like frame comprises woven carbon fiber braids that wind in a clockwise direction or a counterclockwise direction and spirally extend in an extending direction of the carbon fiber spring-like frame, each of the woven carbon fiber braids comprise at least three woven carbon fiber ropes, and each of the woven carbon fiber ropes comprise a plurality of twisted carbon fibers,
• wherein the carbon fiber composite plate dowel comprises a braided structure woven from carbon fibers and a pyrolytic carbon coating, a silicon carbide coating or a pyrolytic carbon/silicon carbide mixed coating on a surface of the braided structure,
• wherein the carbon fiber spring-like frame has 0.1-5 kg/mm of a tensile rigidity coefficient.
