“…The locations of the pores were random and did not show any preference along a certain direction. Similar canals have been found in the inner wall of scorpion stingers, 15 the raptorial appendages of the peacock mantis shrimp, 26 and the crab and lobster exoskeleton. 27−29 The canals had an elliptical cross section with a long axis of around 2 μm (Figure 3h) and were surrounded by fibers oriented along the radial direction of the cross section, forming the pore tube (Figure 3i).…”

The tail spike of the mantis shrimp is the appendage for counteracting the enemy from behind. Here, we investigate the correlations between the chemical compositions, the microstructures, and the mechanical properties of the spike. We find that the spike is a hollow beam with a varying cross section along the length. The cross section comprises four different layers with distinct features of microstructures and chemical compositions. The local mechanical properties of these layers correlate well with the microstructures and chemical compositions, a combination of which effectively restricts the crack propagation while maximizing the release of strain energy during deformation. Finite element analysis and mechanics modeling demonstrate that the optimized structure of the spike confines the mechanical damage in the region near the tip and prevents catastrophic breakage at the base. Furthermore, we use a 3D printing technique to fabricate multiple hollow cylindrical samples consisting of biomimetic microstructures of the spike and confirm that the combination of the Bouligand structure with radially oriented parallel sheets greatly improves the toughness and strength during compression tests. The multiscale design strategy of the spike revealed here is expected to be of great interest for the development of novel bioinspired materials.

“…In the survival war between mantis shrimps and abalones ( Fig. 1A), the abalones are often the prey of mantis shrimps, and in general, the "spear" of mantis shrimps armed with powerful dactyl clubs can often shatter the "shield" of hard abalone (19). This is particularly intriguing because these abalone shells composed of mineral crystals and protein matrix with "brick-and-mortar" arrangements (i.e., nacreous architecture) are themselves considered a benchmark of supertough biocomposites (20)(21)(22)(23)(24).…”

Bioinspired architectural design for composites with much higher fracture resistance than that of individual constituent remains a major challenge for engineers and scientists. Inspired by the survival war between the mantis shrimps and abalones, we design a discontinuous fibrous Bouligand (DFB) architecture, a combination of Bouligand and nacreous staggered structures. Systematic bending experiments for 3D-printed single-edge notched specimens with such architecture indicate that total energy dissipations are insensitive to initial crack orientations and show optimized values at critical pitch angles. Fracture mechanics analyses demonstrate that the hybrid toughening mechanisms of crack twisting and crack bridging mode arising from DFB architecture enable excellent fracture resistance with crack orientation insensitivity. The compromise in competition of energy dissipations between crack twisting and crack bridging is identified as the origin of maximum fracture energy at a critical pitch angle. We further illustrate that the optimized fracture energy can be achieved by tuning fracture energy of crack bridging, pitch angles, fiber lengths, and twist angles distribution in DFB composites.

“…To prove above assumption, inspired by the natural phenomenon that the bivalve mollusk shells with internal residual stresses can withstand the dynamic strike of mantis shrimps, [ 42 ] where the adductor muscles in bivalve mollusks can apply preforces to close the shells when they are attacked by predators, [ 21 ] we constructed a 3D model for the nacre‐like structure with prestresses under impact loading (Figure 1c). Nonlinear finite element modeling simulations revealed that nacre‐like structures with prestress can achieve higher impact resistance (energy dissipation during impaction), where the prestress can promote tablets sliding.…”

The application of prestresses is a valuable strategy for enhancing the overall mechanical performances of structural materials. Residual stresses, acting as prestresses, exist naturally in biological structural materials, such as the nacre with the 3D “brick‐and‐mortar” arrangement. Although regulation of the tablets sliding has recently been demonstrated to be vital to improve toughness in synthetic nacre‐like structures, the effects of prestresses on the tablets‐sliding mechanism in these nacre‐like structures remain unclear. Here, by a combination of simulation, additive manufacturing, and drop tower testing the authors reveal that, at a critical prestress, synergistic effects between the prestress‐enhanced tablets sliding and prestress‐weakened structural integrality result in optimized impact resistance of nacre‐like structures. Furthermore, the prestressing strategy is easily implemented to a designed nacre‐inspired separator to enhance the impact resistance of lithium batteries. The findings demonstrate that the prestressing strategy combined with bioinspired architectures can be exploited for enhancing the impact resistance of engineering structural materials and energy storage devices.
