Abstract Scope |
Fish scales are inspiring new layered engineered materials and next-generation flexible armors. Past studies have focused on the structure and properties of ontogenetic scales. The structure-property relationships of regenerated scales have received limited attention. In this study, several Cyprinus Carpio were acquired from the wild and maintained in an aquatic environment at either 10° or 20°C. Ontogenetic scales were extracted in specific sites to initiate regeneration, and the regenerated scales were extracted after a period of development. The ontogenetic and regenerated scales were compared in terms of their chemical composition, microstructure, and mechanical properties evaluated in uniaxial tension. Regardless of water temperature, the strength, strain to fracture and toughness of the regenerated scales were significantly lower than those of ontogenetic scales. Properties of the scales that regenerated in the 20°C environment were superior to those at 10°C, and depended largely on the mineralized region. Details will be discussed. |
