The HAp-(t-ZrO2) ceramic composites with mimetic osteon microstructures were fabricated to investigate the technical feasibility of fabricating natural bone mimetics by a combination of multi-extrusion and rolling processes. The HAp and graphite powders were mixed with ethylene vinyl acetate and stearic acid using a shear mixer, and the mixture was extruded by the multi-extrusion process to create filaments. A HAp sheet was prepared by a rolling process. The HAp filaments and carbon filaments were arranged one by one on the HAp sheet, and the system was rolled to form a mimetic osteon microstructure. Burning out and sintering processes were performed for removal of the organic binder and graphite and for densification. The pore diameter and core of the mimetic osteon microstructure were approximately 50μm and 150μm, respectively. The porosity and bending strength were approximately 60% and 177MPa, respectively in the sample sintered at 1450°C.
