Outline of Final Research Achievements |
We applied "sacrificial bond principle", which is the principle for toughening of soft materials, to create tough flexible composites consisting of soft and hard phases. Introduction of the sacrificial bond mechanism to either of the two phases leads remarkable energy dissipation during deformation, resulting in lightweight, flexible, and tough composites with fracture resistance up to 10 times greater than that of steel. By further extending this principle, we also succeeded in obtaining materials that become significantly stiffer when heated and materials whose strength increases repeatedly after mechanical stimuli.
