“…Then the samples under 30 J and 65 J enter the rebounding stage, and the loads drop rapidly with the decreasing displacements until 0. Differently, in the 100 J sample, a rebalance phase occurs after reaching the peak [ 17 ]. The load fluctuates and decreases slowly, the displacement continues to increase until the maximal value is reached, after which the sample enters the rebounding stage.…”

“…It is a potential way to study the principles and functionalities found in biological systems to design novel structures with superior mechanical or functional properties. Prior efforts mainly focused on improving the strength, stiffness, and toughness of materials and structures [ 5 , 6 , 7 , 8 ]. The ability of porous biological materials to absorb mechanical energy has been studied over the past few years [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

This paper presents an investigation on the stiffness and energy absorption capabilities of three proposed biomimetic structures based on the internal architecture of a cornstalk. 3D printing was used to manufacture specimens using a tough and impact-resistant thermoplastic material, acrylonitrile butadiene styrene (ABS). The structural stiffness, maximum stress, densification strain, and energy absorption were extracted from the compression tests performed at a strain rate of 10−3 s−1. A numerical model was developed to analyse the behaviour of the biomimetic structures under compression loading. Further, a damage examination was conducted through optical microscopy and profilometry. The results showed that the cornstalk-inspired biomimetic structure exhibited a superior specific energy absorption (SEA) capability that was three times higher than that of the other core designs as reported in the literature.

“…Bone is a highly optimized composite material with outstanding mechanical properties, which has a very complex structure and is organized at different levels (Wang et al, 2020;Ingrole et al, 2021). Composite materials with high strength, light weight (Rahimizadeh et al, 2021) and impact resistance (Wang et al, 2021;Wang et al, 2022) have a wide range of needs in the fields of aerospace, military, vehicles and other fields (Dong et al, 2022;Sharma et al, 2022). Therefore, the research of biomimetic composites can provide inspiration for the design of materials with excellent mechanical properties and meet the special requirements of engineering (Bhudolia and Joshi, 2018;Jiang et al, 2019;Alizadeh and Ebrahimzadeh, 2022).…”

Osteons are composed of concentric lamellar structure, the concentric lamellae are composed of periodic thin and thick sub-lamellae, and every 5 sub-lamellae is a cycle, the periodic helix angle of mineralized collagen fibers in two adjacent sub-lamellae is 30°. Four biomimetic models with different fiber helix angles were established and fabricated according to the micro-nano structure of osteon. The effects of the fiber periodic helical structure on impact characteristic and energy dissipation of multi-layer biomimetic composite were investigated. The calculation results indicated that the stress distribution, contact characteristics and fiber failur during impact, and energy dissipation of the composite are affected by the fiber helix angle. The stress concentration of composite materials under external impact can be effectively improved by adjusting the fiber helix angle when the material composition and material performance parameters are same. Compared with the sample30, the maximum stress of sample60 and sample90 increases by 38.1% and 69.8%, respectively. And the fiber failure analysis results shown that the model with a fiber helix angle of 30° has a better resist impact damage. The drop-weight test results shown that the impact damage area of the specimen with 30° helix angle is smallest among the four types of biomimetic specimens. The periodic helical structure of mineralized collagen fibers in osteon can effectively improve the impact resistance of cortical bone. The research results can provide useful guidance for the design and manufacture of high-performance, impact-resistant biomimetic composite materials.
