Using poly-methyl methacrylate as a pore-forming agent, porous beta-tricalcium phosphate (beta-TCP)/t-ZrO2 composites were fabricated depending on the volume percentages (vol.%) of t-ZrO2 powder. In the porous sintered bodies, hybrid pores, about 20 and 200 mu m in diameter, were homogenously dispersed in the beta-TCP/t-ZrO2 matrix and showed good interconnection. On the other hand, beta-TCP-(t-ZrO2)/polycaprolactone (PCL) composites were fabricated by the melt infiltration process using porous beta-TCP/t-ZrO2 bodies. The relative density of the beta-TCP-(t-ZrO2)/PCL composites increased as the vol.% of t-ZrO2 increased and its maximum value was about 98.6%. However, the hardness, bending strength and elastic modulus of beta-TCP-(t-ZrO2)/PCL composites decreased due to the low densification of porous beta-TCP/t-ZrO2 bodies as the volume percentages of t-ZrO2 content increased. The values (using 20 vol.% of t-ZrO2) were 11.4 Hv, 25.5 MPa and 17.2 GPa, respectively.
