Abstract Scope |
The Organ pipe coral (Tubipora musica) is a species of stony coral that serves as a habitat for small sea creatures called polyps. The survival of these polyps relies heavily on the damage tolerance of the coral's skeleton. In this study, a correlative microscopy-based approach, utilizing x-ray microtomography and scanning electron microscopy was employed to investigate the intricate multiscale structure of the Organ pipe coral. At the macrostructural level, the coral exhibited a distinctive structure characterized by vertical tubes reinforced by horizontal platforms. At the microscale, the coral was composed of cells that were formed through a unique arrangement of submicrometer-sized calcium carbonate plates. To evaluate the mechanical properties of this hierarchical structure, nanoindentation was conducted. The results revealed length-scale dependent toughening mechanisms present within the coral's porous structure. The impact of this hierarchical structure on the development of engineering materials will be discussed. |
