摘要

可回收的能量吸收材料对于推进抗冲击系统至关重要;然而,它们通常受到低能量耗散(<1 MJ·m−3)的限制。加拿大大角羊(Ovis canadensis)的角表现出出色的能量耗散和形状恢复,这是由多尺度机制实现的,包括排列的小管和层状角蛋白细胞,以及水合驱动的自我恢复。受这种分层结构的启发,通过改进的凝胶辅助自组装方法,制备了一种可回收的多孔吸能复合材料,以构建具有层状排列的纳米薄片的微管支架,随后将其渗透到动态共价环氧基质中。优化后的复合材料具有优异的能量吸收(10 MJ·m−3),比传统的可回收建筑材料高出一个数量级,同时具有高抗压强度(50 MPa)、低密度(1.1 g·cm−3)和稳定的循环形状恢复性能。这些力学性能源于协同的多尺度增韧机制,包括管状屈曲(宏观尺度)、层状裂纹挠曲和界面分层(微观尺度)以及基体粘弹性(纳米尺度)。环氧基进一步促进了可逆变形和循环损伤恢复。本研究为工程轻量化、高强度、高能量耗散的可重复使用材料建立了可扩展的仿生策略,解决了潜在防护应用中的关键挑战。

Horn‐Inspired Hierarchical Tubular Composites for Recoverable High‐Energy Absorption
Recoverable energy‐absorbing materials are crucial for advancing impact‐resistant systems; however, they are typically limited by low energy dissipation (<1 MJ·m−3). The horn of bighorn sheep (Ovis canadensis) exhibits outstanding energy dissipation and shape recovery, enabled by multiscale mechanisms including aligned tubules and lamellar keratin cells, along with hydration‐driven self‐recovery. Inspired by this hierarchical architecture, a recoverable porous energy‐absorbing composite through a modified gelation‐assisted self‐assembly method is fabricated to construct a microtubular scaffold with lamellar‐aligned nanoplatelets, which is subsequently infiltrated with a dynamic covalent epoxy matrix. The optimized composite exhibits exceptional energy absorption (10 MJ·m−3), exceeding conventional recoverable architected materials by an order of magnitude, while simultaneously achieving high compressive strength (> 50 MPa), low density (1.1 g·cm−3), and stable cyclic shape recovery performance. These mechanical properties arise from synergistic multiscale toughening mechanisms, including tubular buckling (macroscale), lamellar crack deflection and interfacial delamination (microscale), and matrix viscoelasticity (nanoscale). The epoxy matrix further contributes to reversible deformation and cyclic damage recovery. This study establishes a scalable biomimetic strategy for engineering lightweight, high‐strength, and reusable materials with high energy dissipation, addressing critical challenges in potential protective applications.
