Method for preparing bionic multi-structure artificial bone and application of artificial bone
The invention discloses a method for preparing a bionic multi-structure artificial bone and application of the artificial bone, a fiber composite HA ceramic green body is obtained through a controllable arrangement or 3D printing mode, and then a bionic multi-structure ceramic material is obtained through hot pressing or normal-pressure and vacuum densification sintering and normal-pressure pore-forming heat treatment in sequence. In order to improve the mechanical properties of the porous ceramic, a chopped CF reinforcement is added into the HA powder or HA slurry. The multi-structure ceramic with controllable aperture, controllable porosity and controllable pore distribution is prepared by using continuous fibers as a pore-forming agent, and the preparation of straight-through small pores which cannot be realized by other pore-forming methods is realized. Meanwhile, a mechanical property experiment result shows that the micropores are beneficial to the mechanical property of the porous ceramic.
本发明公开了一种制备仿生多结构人工骨的方法和人工骨的应用，通过可控排布或者3D打印的方式获得纤维复合HA陶瓷坯体，然后依次进行热压或常压、真空致密化烧结，常压造孔热处理获得仿生多结构陶瓷材料。为了改善多孔陶瓷的力学性能，在HA粉末或HA浆料中加入短切CF增强体。使用连续纤维为造孔剂制备出孔径可控、孔隙率可控、孔道分布可控的多结构陶瓷，实现其他造孔方法所不能实现的直通的小孔的制备。同时力学性能实验结果表明微孔有利于多孔陶瓷的力学性能。
