| Outline of Final Research Achievements |
In order to generate calcium carbonate applicable to structural materials that follow biomineralization such as shell and crustaceans, mechanical properties of materials produced by biomineralization such as shell and crab were investigated, and production of calcium carbonate by laser was tried inspiring by lime scale such as water scale. It was revealed that many shells were aragonite, the exterior shell and the scallops were calcite, that the yield stress of aragonite was about 1 GPa and the yield stress of calcite was about 400 MPa using an inverse analysis of an indentation test. It was also demonstrated that calcium carbonate could be generated by irradiating a laser beam to a test specimen placed in the aqueous calcium hydrogen carbonate solution.
