| Research Abstract |
Fracture mechanism of nacre in shell was investigated. The main interest was focused on the role of the organic phase. From evaluation of mechanical properties and observation of microscopic fracture behavior, it was revealed that the sliding behavior at the interface between aragonite plates in nacre was controlled by the organic phase and thereby the excellent mechanical properties were achieved. This behavior was quantitatively understood using a model, which helps obtain a design principle for ceramics composites.
