| Outline of Final Research Achievements |
Carbon fiber reinforced composites, which is composed with resin and carbon fiber, is expected as structural material instead of steel and aluminum alloy due to its superior specific strength and rigidity. However, nondestructive defect diagnosis method for the material has not been established yet. This study succeeded in the development of smart carbon fiber reinforced composites that can detect the occurrence of the defect by itself by electrochemical methods. This kind of composites does not lead the occurrence of inner defect because of not putting sensors inside the material, therefore, has high reliability as structure.
