摘要：The mollusk shells, as a simple biominerals, have developed a rigid calcified shell to protect the soft body against environmental pressures and predators. The paper has studied the effect of the crossed-laminar structure and organic matrix protein on mechanical properties of nanoindentation of the hemifusus tuba conch shell. The results showed that the states of the organic matrix protein were different before heated and after heated, and which changed the mechanical properties of mollusk shells. After heated the mechanical properties decreased seriously. Thus applying the interface models of organic protein and inorganic crystal in the crossed-laminar structure between former and after heating states preferably explain that the mechanical properties are not only correlative to unique microstructure, but also relate with the organic matrix and the bond between the organic matrix and inorganic mineral.
