“…In this perspective, mechanical tests were performed on scales mounted on a soft elastic substrate. The scales were covered with four different types of soft-layered covers, and in some conditions, grit was also used in the soft layer of cover on top of the scales to examine the probability of impact force deflection if a blunt projectile or object is targeted on it (White et al, 2019). It makes a lot of sense to add soft layers of covers with grit particles suspended inside, since it will provide a significant amount of dampening if subject to a blunt projectile.…”

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.

“…Biologically relevant parameters of scale surface morphology, scale friction and epidermal cover were changed in combination to assess their contribution to penetration resistance. Results from this research also suggest that optimized surface treatment can be applied to bioinspired fish skins to increase resistance [18,80].…”

“…In a recent study, inspired by C. carpio scales, a nylon sheet was laser cut and a silicon substrate was cast over the scales; this was embedded in the female mold of the substrate. After demolding, the scales were embedded in the substrate, and a final sample was obtained for testing [80]. To create hierarchical structural materials, UHMWPE plates (as the base material) and fibers were used to manufacture protecto-flexible armor in different configurations ranging from monolithic (one level of structural hierarchy) up to six levels of structural hierarchy.…”

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.

Scales are a path breaking evolutionary adaptation that accompanied vertebrate evolution for the past 500 million years. Inherently lightweight with diverse shapes, sizes, materials, and distribution, they provide remarkable architecture-material enhancement, typical of metamaterials. Here we provide a perspective on mechanical behavior of fish scale inspired structures and explain the origins of some of their striking mechanical properties that include directional nonlinearity, interlocking behavior, and multiple penetration modes. We outline and explain the progress in understanding the complexities of these structures in global and local deformation modes and conclude by offering future perspectives and challenges.
