Fabrication of Artificial Bone through the Imitation of human bone |
| 초록 |
In this work, HAp-(t-ZrO2) ceramic composites of biomimic artificial bone were fabricated by multi-extrusion process in order to replace nature bone. HAp-(t-ZrO2) and graphite powders were mixed separately with ethylene vinyl acetate (EVA) and stearic acid using shear mixer. Extruded HAp-(t-ZrO2) filaments and carbon filaments were arranged in the die to fabricate the first pass filament. The first pass filaments were arranged in the same die with a central carbon core for making the space for spongy bone. Burning out and sintering processes were performed to remove the binder and lubricant. The microstructure channel diameter was researched around 300㎛. Microstructure analysis was carried out by OM, SEM, and µ-CT. Compressive strength was investigated for the artificial bone. Some preliminary bio-compatibility test was evaluated |
