“…The delamination in each interface rotates by a small angle from the previous one, and these delaminations are linked by matrix splits and spiral upwards, similar to a pair of spiral staircases. This is the unique damage pattern of helicoidally stacked fiber-reinforced laminates and is referred to as a spiraling matrix split [ 18 , 22 , 25 ]. Liu et al [ 25 ] and Suksangpanya et al [ 34 ] reported that spiraling matrix split is a form of matrix crack that grows between fibers.…”

“…In the helicoidal structure, the orientation of the fibers in one layer is offset at a slight angle with respect to the fibers in the layer below, forming a spiraling helicoidal configuration. Inspired by these findings, several researchers have conducted studies that mimic the helicoidal structure using CFRP laminates [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. The results show that helicoidal layup significantly improves low-speed impact [ 12 , 13 , 14 , 15 , 16 , 17 ] and high-speed impact performance [ 18 ] of CFRP laminates.…”

“…Several studies [ 18 , 20 , 22 , 23 , 24 , 25 , 26 ] reported that the helicoidal structure also reduces fiber damage in CFRP laminates as well as natural-fiber-reinforced polymer laminates. This is achieved by dissipating energy through mainly helicoidal matrix damage, namely, diffused matrix cracks and delaminations.…”

Glass-Fiber-Reinforced Polymer (GFRP) laminates are widely used in the automotive and marine industries such as auto bodies and boat hulls. Decreasing the weight and improving the reparability of GFRP parts will cut down material usage, fuel consumption and repair costs. This study shows a bio-inspired helicoidal stacking configuration that significantly improves the impact performance and fiber damage resistance of GFRP laminates. For similar impact performance in terms of perforation energy, the helicoidal GFRP laminate is 20% lighter than the conventional quasi-isotropic GFRP laminate. Upon impact, delaminations and matrix splits link-up and grow extensively throughout the helicoidal laminate. This effectively reduces fiber damage and improves impact performance. Because helicoidal GFRP laminates are resistant to fiber damage and composite healing agents can effectively repair non-fiber damage, embedding healing agents into helicoidal GFRP results in lightweight, inexpensive and healable laminates.

“…Since these fish contain collagen fibrils beneath their scales and are covered with an extremely dense mineralized material over the top, the scales act very effectively in providing the protection required and the flexibility needed in a combat situation. The effective armor-like properties in these scales arise due to the helicoidal or twisted cross plywood-like orientation of each lamellae of collagen fibers with the convincing distribution of forces and energy upon impact loading (Liu et al, 2020). However, teleost fish is also considered to demonstrate great mechanical properties in similar conditions where penetration resistance is favored, but they possess an anomaly in both dry and hydrated conditions of the scale while from different regions on the body of fish (Rawat et al, 2021).…”

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.

This paper investigates the impact of hybrid fiber structures on the ballistic performance of columnar ceramic/interlayer hybrid fiber composites. Three hybrid fiber composites and one single fiber‐component composite were fabricated. The accuracy of the numerical model was validated through quantitative analysis of matching micro‐CT images with simulation results. The error of the back convex height (BCH) values between the numerical simulation and the micro‐CT was only 2.8%. The error of delamination area at four thickness positions is only 0.7%, 14.7%, 0.3%, and 5.3%, respectively. The quantitative study on the ballistic performance of ceramic/fiber composites indicates that all hybrid fiber composites provide enhanced penetration resistance, with the sandwich structure outperforming the rest. Compared with the C‐U sample, the bullet's remaining velocity and the BCH in the C‐(A/U/A) sample were significantly improved, with reductions of 195 m∙s−1 and 16.6 mm, respectively. During the penetration process, the ceramic/fiber composites mainly exhibited damage failure mechanisms such as ceramic crushing to form ceramic cones, shear failure, and shear‐tensile‐delamination mixed failure. The energy absorption rate (EAR) of ceramic failure was 54.1%–60.2%, the EAR of tension was 12.5%–20.9%, and the EAR of the tension‐delamination‐shearing mixed model was 21.9%–32.8%.Highlights The numerical model is quantitatively validated with micro‐CT results. Ballistic resistance and EARs in six stages are quantitatively analyzed. C‐(A/U/A) composite has superior ballistic resistance compared to C‐U.
