Outline of Final Research Achievements

I succeeded in development of magnesium/calcium phosphate laminated composite. Furthermore, it was shown that the volume fraction and position of calcium phosphate can be arbitrarily controlled by optimizing the processing conditions.
It was confirmed that the yield strength and degradation resistance of the composite increased linearly with the volume fraction of calcium phosphate. It can be said that magnesium/calcium phosphate composites with the intended properties can be fabricated by controlling the volume fraction of calcium phosphate.

Academic Significance and Societal Importance of the Research Achievements

整形外科領域において、生体内分解性デバイスの需要は高い。また、生体骨組織は体を支持するために、異方的な構造を示すため、骨組織の異方性に合わせたデバイスの開発がQOLの向上に有効であることが明らかとなっている。本研究により、骨類似の異方性を示し、骨との親和性の高い生体内分解性材料が開発できた。本材料を用いたデバイスの開発は、使用者のQOL向上につながると考えられる。
