“…Periodic helicoidal arrangements are obtained by manual stacking of prepregs in controlled sequences. 30,[61][62][63][64][65][66][67] Most laminated samples are flat and horizontal, but using molds with shapes and curvatures is feasible and have been used to reproduce the herringbone structure, for example (Figure 7A). 67…”

“…Extensive studies have been performed over the past ten years to uncover the structural optimization strategies and toughening mechanisms of the stomatopod dactyl, generating numerous characterization results, and various intrinsic and extrinsic toughening mechanisms have been derived (Weaver et al, 2012;Amini et al, 2014Amini et al, , 2015Yaraghi et al, 2016;Grunenfelder et al, 2018;Huang et al, 2020;Chua et al, 2021). To date, these studies have already provided innovative inspirations for the manufacture of high-energy absorption and impact-resistant composite materials in industry (Han et al, 2020;Liu et al, 2019;Rivera et al, 2020). One of the first comprehensive reports on stomatopod cuticles suggested they are made of three distinct regions: the impact region, the periodic region and the striated region (Weaver et al, 2012) [Fig.…”

The structure and mechanical properties of the stomatopod dactyl club have been studied extensively for its extreme impact tolerance, but a systematic in situ investigation on the multiscale mechanical responses under high-speed impact has not been reported. Here the full dynamic deformation and crack evolution process within projectile-impacted dactyl using combined fast 2D X-ray imaging and high-resolution ex situ tomography are revealed. The results show that hydration states can lead to significantly different toughening mechanisms inside dactyl under dynamic loading. A previously unreported 3D interlocking structural design in the impact surface and impact region is reported using nano X-ray tomography. Experimental results and dynamic finite-element modeling suggest this unique structure plays an important role in resisting catastrophic structural damage and hindering crack propagation. This work is a contribution to understanding the key toughening strategies of biological materials and provides valuable information for biomimetic manufacturing of impact-resistant materials in general.

“…The honeycomb was implemented in motorcycle helmets for head protectors during road traffic accidents involving motorcyclists due to its high energy absorption (Li et al, 2020). From the researcher's side, fibers as substances or materials were required to explore from various resources to fulfill the material industry's performance, reliability, toughness, and resistance Natural fiber-reinforced honeycomb has shown promising results in increasing honeycomb strength and fascinating mechanical properties (Han et al, 2020;Atiqah et al, 2020;Kumar et al, 2021;Ocieczek et al, 2021;Shieddieque et al, 2021). This was an inspiration to combine biological fiber with environment-friendly materials while improving the mechanical performance of honeycomb.…”

“…This was an inspiration to combine biological fiber with environment-friendly materials while improving the mechanical performance of honeycomb. They successfully developed a sandwich honeycomb with basalt fiber and a unidirectional skin sandwich-structural honeycomb to improve flexural and energy absorption (Han et al, 2020). Other studies have found that honeycomb with natural fiber could be a viable replacement for synthetic fiber as a reinforcement in polymer composites due to improvements in hardness testing (Atiqah et al, 2020).…”

The honeycomb sandwich structure has been extensively investigated for its mechanical performance. Modification in improving such mechanical properties is an innovation required for honeycomb sandwiches, especially by adding a random fibers reinforcement inside a sheet panel plate. This study was developed random fiber reinforcement using natural fiber of Oil Palm, Sugar Cane, and Coconut, which constructed by the commercial software code of MATLAB. This investigation analyzed the performance of three-point bending behavior using the finite-element model, which provides four levels of fiber condition to observed: 0, 50, 100, and 150 fiber numbers. Ansys Workbench/Dynamic code was chosen to predict mechanical performance such as stress and displacement analysis. In the fiber development study, a series of numerical simulations were carried out with two types of fiber orientation reinforcement, unidirectional and chopped randomly. The hybrid orientation was also implemented in this research by combining unidirectional and chopped fiber, which was fixed at 150 numbers and then varied in three sets: S50/C100, S100:C50, and S75/C75. As a result, it was confirmed that the fiber reinforcement enhances the stiffness of the structure, which contributed a lot to the promotion of the bending resistance capacity and energy absorption. Especially, unidirectional fiber orientation has shown a significant increase in absorbing stress during testing. The fiber reinforcement sandwich demonstrated better mechanical behavior in the simulation, as reported by the hybrid system, and this was influenced by the unidirectional orientation.
