“…The fabricated material showed inelastic fracture behavior in a bending test rather than brittle fracture. In another work using the Al 2 O 3 flake powder, the powder was trapped in gel, aligned during drying and then hot-pressed [128]. The composites with platelet volume fractions up to 50% were fabricated.…”

“…Several works utilized flake ceramics powder or layered clay as a reinforcing inorganic platelet material and mixed it with matrix using a variety of ways of aligning the inorganic platelets [127][128][129][130][131]. Thin Al 2 O 3 flake powder was aligned by slip casting and then hot-pressed in an epoxy matrix, yielding a flake volume fraction of 60% [127].…”

The structure and the toughening mechanism of nacre have been the subject of intensive research over the last 30 years. This interest originates from nacre's excellent combination of strength, stiffness and toughness, despite its high, for a biological material, volume fraction of inorganic phase, typically 95%. Owing to the improvement of nanoscale measurement and observation techniques, significant progress has been made during the last decade in understanding the mechanical properties of nacre. The structure, microscopic deformation behavior and toughening mechanism on the order of nanometers have been investigated, and the importance of hierarchical structure in nacre has been recognized. This research has led to the fabrication of multilayer composites and films inspired by nacre with a layer thickness below 1 µm. Some of these materials reproduce the inorganic/organic interaction and hierarchical structure beyond mere morphology mimicking. In the first part of this review, we focus on the hierarchical architecture, macroscopic and microscopic deformation and fracture behavior, as well as toughening mechanisms in nacre. Then we summarize recent progress in the fabrication of materials inspired by nacre taking into consideration its mechanical properties.

“…Platelet-like inorganic building blocks, such as glass flakes [24], layered nature clays [9,21,22,25], ceramic alumina platelet [12,26], layered double hydroxides [27], and flattened double-walled carbon nanotube [28] have been used for the fabrication of nacre-like composites. Moreover, graphene, a two-dimensional (2D) carbon platelet with one-atom thickness, has attracted tremendous interest because of its exceptional electrical, thermal, and mechanical properties [29][30][31].…”

“…This structural material exhibits a toughness (in energy terms) some orders of magnitude higher than that of its primary component (CaCO 3 ), and its strength is among the highest in shell structures [1][2][3]. Inspired by this structure, there have been significant efforts in the past decades to synthesize new materials with mechanical performance comparable to nacre in the past decades [4][5][6][7][8][9][10][11][12][13][14][15]. The essence of success is to understand the deformation mechanisms inherent in nacre.…”

Outstanding mechanical properties of biological multilayered materials are strongly influenced by nanoscale features in their structure. In this study, mechanical behaviour and toughening mechanisms of abalone nacre-inspired multilayered materials are explored. In nacre's structure, the organic matrix, pillars and the roughness of the aragonite platelets play important roles in its overall mechanical performance. A micromechanical model for multilayered biological materials is proposed to simulate their mechanical deformation and toughening mechanisms. The fundamental hypothesis of the model is the inclusion of nanoscale pillars with near theoretical strength (s th E/30). It is also assumed that pillars and asperities confine the organic matrix to the proximity of the platelets, and, hence, increase their stiffness, since it has been previously shown that the organic matrix behaves more stiffly in the proximity of mineral platelets. The modelling results are in excellent agreement with the available experimental data for abalone nacre. The results demonstrate that the aragonite platelets, pillars and organic matrix synergistically affect the stiffness of nacre, and the pillars significantly contribute to the mechanical performance of nacre. It is also shown that the roughness induced interactions between the organic matrix and aragonite platelet, represented in the model by asperity elements, play a key role in strength and toughness of abalone nacre. The highly nonlinear behaviour of the proposed multilayered material is the result of distributed deformation in the nacre-like structure due to the existence of nano-asperities and nanopillars with near theoretical strength. Finally, tensile toughness is studied as a function of the components in the microstructure of nacre.
