“…For instance, in fish scales, dehydration causes resistance to sliding between collagen fibers, which increases the elastic modulus and strength of dehydrated scales [25,37]. The stiffening mechanisms associated with this phenomenon have already been reported by Jiang et al [39]. Similarly, in synthetic systems such as liquid armor, the highperformance fabrics increase their mechanical properties via resistance to fiber sliding promoted by the introduction of shear thickening fluids (STF) [40].…”

The quest for new light-weight materials with superior mechanical properties is a goal of materials scientists and engineers worldwide. A promising route in this pursuit is drawing inspiration from nature to design and develop materials with enhanced properties. By emulating the graded mineral content and hierarchical structure of fish scales of the Arapaima gigas from the nano to macro scales, we were able to develop bioinspired laminated composites with improved impact resistance. Activated by the addition of nano-particles of Al 2 O 3 and nano-layers of TiN to a thermoplastic fiber substrate, new energy dissipation mechanisms operating at the nanoscale enhanced the energy absorption and stiffness of the bioinspired material. Remarkably, the newly developed materials are easily transferred to the industry with minimum associated manufacturing costs.

“…A similar study [58] was performed to find the mechanical properties of fish scales under tensile testing, and the DIC and microscopic images showed that the tensile strength of carp scales was dependent on the number of layers of collagen fiber in their inner layers [58]. The scales of a black carp (Mylopharyngodon piceus) were analyzed with tensile testing and DIC to find the mechanical properties and the effects of different scale positions (head or tail) on mineralization and dehydration [59].…”

Fish scales inspired materials platform can provide advanced mechanical properties and functionalities. These materials, inspired from fish scales take the form of either composite materials or multi-material discrete exoskeleton type structures. Over the last decade, they have been under intense scrutiny for generating tailorable and tunable stiffness, penetration and fracture resistance, buckling prevention, nonlinear damping, hydrodynamic and camouflaging functions. Such programmable behavior emerges from leveraging their unique morphology and structure-property relationships. Several advanced tools of characterization, manufacturing, modeling and computation have been employed to understand and discover their behavior. With the rapid proliferation of additive manufacturing (AM) techniques, and advancing envelope of modeling and computational methods, this field is seeing renewed efforts to realize even more ambitious designs. We present a review and recapitulation of the state-of-the art in fish scale inspired materials in this paper.

“…On a different perspective, given that arapaima scales can be further strengthened at a molecular bonding level, providing new techniques in the development of flexible armors, an organic solvent like ethanol proved to be very effective in strength increment and puncture resistance for low mineralized scales, which are usually present and obtained from the lower middle to tail region of these fishes (Arola et al, 2019). These strengthening mechanism works on the collagen fibrils as hydrogen bonding begins to form among the solvents that could be methanol, ethanol, and acetone, providing good and enhanced mechanical properties (Jiang et al, 2020). To add, fiberreinforced composites (FRCs) can also be considered as a very effective way to construct and mimic the collagenous formation in a material, as FRCs provide favorable mechanical properties and also are quite popular (Yaraghi and Kisailus, 2018).…”

Biomaterials are evolving quite rapidly over the last decade. Many applications have been considered toward their involvement in saving lives in the line of duty for law enforcement agencies and military operations. This article discusses recent work on the role of biomaterials that can be considered as a competitive alternative to composites, being used against ballistic impacts. The fish-scaled biomaterials are focused on in this paper, highlighting their excellent mechanical properties and structural configurations. In its natural environment, the scale provides fishes with an armor plating, which is significantly effective in their survival against attacks of predator and the impact inflicted from sharp teeth. These bioinspired materials, if engineered properly, can provide an excellent alternative to current Kevlar® type armors, which are significantly heavier and can cause fatigue to the human body over long-term usage. The investigated materials can provide effective alternatives to heavier and expensive materials currently used in different industrial applications. Additionally, some recent development in the usage of fish scales as a biomaterial and its applications in rapid prototyping techniques are presented. Finally, this review provides useful information to researchers in developing and processing cost-effective biomaterials.
