“…The best example of this phenomenon is the dactyl club of the Mantis shrimp, where a α-chitin template is mineralized in the exocuticle by an oriented crystalline hydroxyapatite. This forms the Bouligand-type structure, and as a result, the stomatopod's club is able to withstand multiple high-energy impacts [97]. Similar phenomenon has been noticed for lobsters of Homarus americanus, where the exoskeleton is a multilayered composite tissue consisting of crystalline chitin and various types of proteins.…”

“…"Prestructured" naturally occurring tube-like chitin-based scaffolds (Figure 2) have so far only been isolated from demosponges. Principally, a chitin molecule has C=O, N-H and O-H functional groups, resulting in an affinity for calcium phosphates, carbonates, and silicates [67,97,112,113]. Consequently, the unique nanofibrous architecture of chitin-based scaffolds isolated from sponges ( Figure 3) can serve as a structural template for promoting biomimetic in vitro synthesis of numerous inorganic phases, both amorphous and crystalline, under selected conditions.…”

“…Chitin plays a major role in biological structural materials with significant physical attributes, such as lobster shells [44], the mineralized dactyl club of the stomatopods [97,112], diatoms cell [20], glass sponges [52], copepod teeth's [115], spider fangs [116] and nacre [117]. Surprisingly, the industrial uses of chitinous materials have been largely based on its chemical characteristics (e.g., high nitrogen content) and unique biological properties, rather than on its ability to form structural composites with novel mechanical properties [117].…”

Abstract:In this mini-review, we shall first cover a short history of the discovery of chitin isolated from sponges; as well as its evolutionarily ancient roots. Next, we will delve into the unique structural, mechanical, and thermal properties of this naturally occurring polymer to illuminate how its physicochemical properties may find uses in diverse areas of the material sciences. We show how the unique properties and morphology of sponge chitin renders it quite useful for the new route of "Extreme Biomimetics"; where high temperatures and pressures allow a range of interesting bioinorganic composite materials to be made. These new biomaterials have electrical, chemical, and material properties that have applications in water filtration, medicine, catalysis, and biosensing. OPEN ACCESSPolymers 2015, 7 236

“…• Impact resistant fiber composites based upon the dactyl club of the mantis shrimp [208]: these carbon fiber-epoxy composites are fabricated to mimic the helical structural design of the dactyl club. Similar to the mantis shrimp itself, when impacted, these bioinspired composites can reduce the through-thickness damage propagation.…”

“…Carbon-fiber epoxy composite laminates mimicking the helicoidal architecture of the periodic region have been found to exhibit improved impactresistance in comparison to traditional quasi-isotropic aerospace designs. [41] 3D printed biomimetic herringbone and helicoid structures were fabricated and tested to failure under compressive loading. Figure 5F shows the 3D printed helicoid (left) and herringbone (right) cylindrical parts.…”

A Sinusoidally Architected Helicoidal Biocomposite

A fibrous herringbone-modified helicoidal architecture is identified within the exocuticle of an impact-resistant crustacean appendage. This previously unreported composite microstructure, which features highly textured apatite mineral templated by an alpha-chitin matrix, provides enhanced stress redistribution and energy absorption over the traditional helicoidal design under compressive loading. Nanoscale toughening mechanisms are also identified using high load nanoindentation and in-situ TEM picoindentation. A Sinusoidally-Architected Helicoidal BiocompositeBy Nicholas A. Yaraghi, Nicolás Guarín-Zapata, Lessa K. Grunenfelder, Eric Hintsala, Sanjit Bhowmick, Jon M. Hiller, Mark Betts, Edward L. Principe, Jae-Young Jung, Leigh Sheppard, Richard Wuhrer, Joanna McKittrick, Pablo D. Zavattieri Keywords: (Composites, Toughness, Impact, Biomineral, Ultrastructure) Submitted to 3 Biologically mineralized composites offer inspiration for the design of next generation structural materials due to their low density, high strength and toughness currently unmatched by engineering technologies. [1][2][3][4][5][6][7][8][9] Such properties are based on the ability for the organism to utilize structural organics and acidic proteins to guide and control the mineralization process to yield hierarchical architectures with well-defined compositional gradients.One notable example is the highly developed raptorial appendage, or dactyl, of the stomatopods, a group of aggressive marine crustaceans that use these structures for feeding upon hard-shelled and soft-bodied prey. [10][11][12][13][14] The dactyls of the "smashers", those that feed primarily on hard-shelled prey, (see Figure 1A) takes the form of a bulbous club ( Figure 1B), which is used to smash through mollusk shells, crab exoskeletons, and other tough mineralized structures with tremendous force and speed. [11][12][13][14][15][16] Achieving accelerations over 10,000g and reaching speeds of 23 m/s from rest, the dactyl strike is recognized as one of the fastest and most powerful impacting events observed in Nature. [11,12] The club is capable of delivering and subsequently enduring repetitive impact forces up to 1500 N and cavitation stresses without catastrophically failing, demonstrating its utility as an exceptionally damage-tolerant natural material.The origins of such a mechanical response lie in the structural design. Previous work identified the club as a multi-regional composite material containing an organic matrix composed of alpha-chitin fibers mineralized by amorphous forms of calcium carbonate and calcium phosphate as well as crystalline apatite. [17,18] These investigations revealed mechanisms responsible for providing damage-tolerance and impact-resistance to the club, which were largely attributed to the interior of the club (periodic region), identified as the primary energy-absorbing layer. [17,18] The combination of soft polymeric nanofibers and stiffer mineral provides a periodic modulus mismatch leading to crack deflection, which in co...
