Outline of Final Research Achievements |
Composites as structural materials are important in the aerospace and other fields requiring lightweight, high-strength, and high-rigidity structural materials, but because of their complex structure, the origin of their mechanical properties has not been elucidated at the microscopic level, such as chemical bonding and atomic-level structure. In this study, we found that point defects in the less reactive carbon nanotubes enhance the bonding to resin while at the same time the unique strength of carbon nanotubes is not degraded. This indicates that microstructural elements such as defects are the key to improving the strength of composite materials.

Academic Significance and Societal Importance of the Research Achievements |
複合材料は航空・宇宙分野をはじめとする軽構造が大きな役割を果たす分野において重要な構造材料である。性能の設計指標が解明されていない複合材料について、化学結合や原子レベルの構造といった、電子や原子という微視的観点から研究するアプローチは稀であったが、当該手法を適用したことより複合材料における化学結合の重要性が明らかとなった。性能向上の指針を示した。これにより、試行錯誤的に性能変化を調べるのではなく、根拠に基づくより効率的な複合材料開発が可能となる。
