Studying naturally growing composites such as nacre give us a fantastic vision to design and fabricate tough, stiff while strong composites. Nacre is a great example of natural ceramic-based strong and tough composites. In a part of the research, freeze-casting method was employed to fabricate nacre-inspired multilayered materials. Mechanical and fracture properties of these man-made composites were also discussed and a theoretical model was proposed to describe the deformation mechanisms. In that study, our results pronounced the effect of interface properties on the mechanical response of multilayered composites. Hence, we were led to investigate the effect of interfaces in nacre. In order to provide the outstanding mechanical functions, nature has evolved complex and effective functionally graded interfaces. Particularly in nacre, organic-inorganic interface in which the proteins behave stiffer and stronger in proximity of calcium carbonate minerals provide an impressive role in structural integrity and mechanical deformation of the natural composite.
