“…The results showed that helicoidal laminates with larger inter-ply angles (16.3 deg and 25.7 deg) slightly outperform quasi-isotropic laminates by 16% and 18%, respectively, in terms of peak compressive loading, whereas the helicoidal laminates with the smallest inter-ply angle (7.8 deg) perform worse than quasi-isotropic laminate by 13%. Ginzburg et al [11] and Jiang et al [12] also conducted low speed impact tests on the helicoidal laminates and showed results similar to Grunenfelder et al [10] that helicoidal laminates with larger inter-ply angle outperform the ones with smaller inter-ply angles. Grunenfelder et al [10] reported a new form of damage pattern that degrades the laminate while helicoidal samples show little fiber damage, and the delamination that spread to the edge of the helicoidal laminate would also weaken the laminate significantly, and the delamination are more prone to spread with smaller inter-ply angle.…”

“…While many researchers focus on improving the mechanical performance of laminates through the development of new materials and additives, manipulating the failure mechanism through the structural design of existing laminates could also significantly improve their mechanical performance [1][2][3]. Inspired by the exoskeletal structure of crustaceans by Bouligand [4], several researchers have conducted studies by mimicking the bio-inspired helicoidal structure using carbon fiber laminates [5][6][7][8][9][10][11][12][13][14][15]. Apichattrabrut and Ravi-Chandar [5] were among the first to conduct study on the mechanical performance of the helicoidal laminate using carbon-epoxy laminate.…”

Helicoidal laminates mimicking the laminar structure of the exoskeleton of crustaceans have been reported to resist higher out-of-plane loads than the common cross-ply and quasi-isotropic fiber-reinforced laminates. Some have reported that smaller inter-ply angle improves strength of helicoidal laminates but others have reported the opposite. A few important material parameters that dictate the failure mechanism of helicoidal laminates have recently been proposed based on proof-of-concept carbon fiber-reinforced laminates, which is not the best material system to benefit from a helicoidal configuration. This study investigates the out-of-plane loading performance of helicoidal laminates with various inter-ply angles, ply thicknesses, and materials. Result shows that the failure mechanism is dictated by the competition between spiraling matrix split and delamination followed by fiber breakage regardless of the laminate material system. Spiraling matrix split resistance decreases as pitch (ratio of inter-ply angle to ply thickness) and matrix toughness decreases. This study provides guidelines for the optimization of helicoidal laminates. Coexistence of spiraling matrix split and fiber damage is often seen on the failed laminate with the highest peak load. The optimal inter-ply angle provides the optimal spiraling matrix split resistance; so, neither spiraling matrix split nor fiber/delamination damage becomes dominant. Since resistance to spiraling matrix split decreases as pitch or matrix toughness decreases, the optimal inter-ply angle will increase for laminates with weaker matrix or thicker plies and vice versa.

“…As we all know, bionic design is a very interesting and effective design method that can improve the mechanical properties of regular structure. Therefore, many scholars are inspired by the biological structures and designed many new types of crashworthy structures [22][23][24][25][26][27][28][29][30][31][32]. Zou et al [24] designed a bionic tube consisting of a bionic node, a bionic unit and an inner tube, the results show that the gradient distribution of the vascular bundle and the node can improve energy absorption.…”

In order to seek higher crashworthiness and energy absorption capacity, based on biological inspiration, a novel bio-inspired re-entrant honeycomb (BRH) structure with negative Poisson's ratio is designed by selecting lotus leaf vein as biological prototype. The numerical simulation model is established by the nonlinear dynamics software ABAQUS and further compared with the available reference results to verify the feasibility. The dynamic compression behavior and energy absorption capacity of two types of BRH (BRH-Ⅰ and BRH-Ⅱ) are firstly compared with conventional re-entrant honeycomb (RH). The simulation results show that BRH have better mechanical properties and energy absorption characteristics. Then, the crushing behavior of BRH-Ⅱ under different impact velocities are systematically studied. Three typical deformation modes of BRH-Ⅱ are observed through the analysis of deformation profile. The quasi-static plateau stress is closely related to the cellular structure. Based on one-dimensional shock theory, the empirical equations of dynamic plateau stress for BRH-Ⅱ with different relative densities are given by using least-square fitting. In addition, the effects of impact velocity and relative density on plateau stress and energy absorption behavior are also studied. The results show that the energy absorption capacity of BRH-Ⅱ is increased nearly six times compared with RH at the same impact velocity.

“…At the nanoscale, cortical bone is mainly composed of organic phase [13] and inorganic phase, the organic phase is mainly formed by mineralized collagen fibrils [14]. Mineralized collagen fibers are ubiquitous in various biological materials and are mainly arranged helicoidally [15], and there are extensive researches on multilayer fiber bionic composite [16][17]. However, the mineralized collagen fibers in osteons have their own uniqueness, which are periodic helicoidal arranged and every 5 sub-lamellae constitute a lamella.…”

Background: As a typical biological material, bone have excellent mechanical properties and plays an important role in supporting the animal body and protecting organs, osteon is an important part of bone. It is found that the osteon is composed of thin and thick lamellae which are periodic and approximately concentric, every 5 lamellae is a cycle, the periodic helix angle of mineralized collagen fibers in two adjacent sub-lamellae is 30°. Four biomimetic composite models with different fiber helix angles were established and fabricated according to the microstructure of mineralized collagen fibers in osteon. Based on the impact analysis of four kinds of bionic composite models, the effects of the fiber periodic helicoidal structure on the impact resistance and energy dissipation of multi-layer bionic composite were investigated. Results: The analysis results show that the fiber helix angle affects the impact damage resistance and energy dissipation of multi-layer fiber reinforced composites. Among the four kinds of multi-layer composite models, the composite model with helix angle of 30° has better comprehensive ability to resist impact damage. The test results show that the impact damage area of the specimen with 30° helix angle is smallest among the four types of bionic specimens, which is consistent with the results of finite element impact analysis. Furthermore, in the case of no impact damage, the smaller the fiber helix angle is, the more uniform the stress distribution is and more energy is dissipated in the impact process. Conclusions: The periodic helicoidal structure of mineralized collagen fibers in osteon are the result of natural selection of biological evolution. This structure can effectively improve the ability of cortical bone to resist external impact. The research results can provide useful guidance for the design and manufacture of high-performance and strong impact resistant biomimetic composites.
