Porous metallic materials can have a low Young's modulus, which is approximately equal to that of the human bone, by controlling the porosity. On the other hand, certain medical polymers exhibit bio-functionalities that are not intrinsically present in metallic materials. Therefore, a composite consisting of these materials is expected to possess both these advantages for biomedical applications. However, in the case of using porous metallic materials, the deterioration of mechanical properties should be concerned because the stress concentration may be induced near the pores. In this study, for the fabrication of the abovementioned composite, porous titanium bulks with different porosities were fabricated by powder metallurgy using atomized titanium powders with various diameters, and then a versatile process for filling a medical polymer (polymethylmethacrylate (PMMA) into fabricated porous titanium bulks (pTi) was developed. Then, the tensile strength and Young's modulus of pTi filled with PMMA (pTi/PMMA) fabricated using this process are systematically investigated.
