3D nacre-inspired bulk materials reinforced by ordered bridges. Morphology of a freeze-dried samples, b sintered samples, and c CE interfiled composites, all of which show a bridge-reinforced lamellar structure (also called a 3D interlocking structure). d Typical bending stress–strain curves. e Typical compressive stress–strain curves from both quasi-static and dynamic tests. f A summary of the flexural strength and strain of 3D IL, LC, and reference bulk ceramic/polymer composites. g A summary of the specific strength and density of alumina-based composites. h–j Crack propagation process observed in situ by SEM. k Sketch of the toughening mechanism under quasi-static conditions. l Sketch of the strengthening mechanism under dynamic conditions.
