Abrégé

The invention discloses a carbon fiber composite artificial bone and a preparation method thereof. The artificial bone includes a carbon fiber composite spring-like frame or includes a carbon fiber composite spring-like frame and a carbon fiber composite plate dowel, and the carbon fiber composite plate dowel is inserted into one end or both ends of a cavity of the spring-like frame or penetrates through the cavity of the carbon fiber composite spring-like frame. The preparation method includes: preparing a spring-like carbon fiber preform through a weaving technology by using carbon fibers as a raw material, performing densification and high-temperature purification treatment and preparing a wear-resistant coating to obtain the carbon fiber composite spring-like frame; and combining the carbon fiber composite spring-like frame with the carbon fiber composite plate bowel to obtain the artificial bone.

Abrégé

A carbon-fiber composite artificial bone and preparation method thereof, the artificial bone comprising a carbon-fiber composite helical frame or comprising a carbon-fiber composite helical frame and a carbon-fiber composite pin member. The carbon fiber composite pin member is insertedly arranged at one end or at two ends of a cavity of the helical frame, or is arranged so as to longitudinally pass through said cavity of the carbon-fiber composite helical frame. The preparation method utilizes carbon fiber as a raw material and preparing by means of a weaving process a helical carbon-fiber preform, then by means of densification, high-temperature purification and preparation of a wear-resistant coating layer, obtaining the carbon-fiber composite helical frame. The carbon-fiber composite helical frame is assembled with the carbon-fiber composite pin member to obtain artificial bone. The present artificial bone is light, has good biocompatibility and good mechanical performance, and particularly has high elastic deformability and excellent resilience, and can realize the functions and shapes of cartilaginous portions, thus having high practical utility.
