High-toughness super-wear-resistance artificial bone for repairing bone defects and preparation method thereof

The invention provides a high-toughness super-wear-resistance artificial bone for repairing bone defects. The artificial bone has a structure of inner and outer layers, wherein the inner layer is an artificial bone rack made of PEEK resin, and is compounded with barium glass fibers and calcium carbonate whiskers; the outer layer the outer layer of the artificial bone rack is coated with a hardened compact layer which is sintered by bio-active glass ceramics; and a porous layer formed by bioactive glass ceramics is attached to the surface of the compact layer. The bonding performing of bioactive glass ceramics with bone is higher than that of hydroxyapatite, and the bonding performance of PEEK resin with bioactive glass ceramics is better than that of carbon fibers with hydroxyapatite, so that the artificial bone has enough mechanical performance and good biocompatibility, and has the mechanical performance, biocompatibility and bone bonding strength is superior than those of a conventional artificial bone product.
