Natural materials represent ideal biomimetic models for materials design. However, the sophisticated natural hierarchical architectures are rather difficult to be implemented in synthetic FRCs and components through classic manufacturing methods. We propose a new method, called squeeze-winding (SW), specifically designed for the fabrication of FRC-tubes with a bone-inspired internal structure. SW represents a modification to the classic filament winding (FW) and is aimed at implementing a bone-like structure characterized by axially-oriented cylindrical features and achieving a high reinforcement volume fraction (∼60%). The outcome of compression testing shows: a high repeatability of the mechanical characteristics achieved by SW, a higher fiber volume fraction of SW tubes compared to the conventional FW tubes, and improved mechanical properties. Moreover, we demonstrate how SW can be used to manufacture a sophisticated bio-inspired design, which mimics the cortical bone microstructure, ensuring enhanced mechanical properties compared to laminated tubes obtained by FW.

天然材料代表了用于材料设计的理想仿生模型。但是，通过经典的制造方法很难在合成FRC和组件中实现复杂的自然分层体系结构。我们提出了一种称为挤压缠绕（SW）的新方法，该方法专门设计用于制造具有骨骼启发性内部结构的FRC管。SW是对经典长丝缠绕（FW）的改进，旨在实现具有轴向圆柱形特征的骨状结构，并实现较高的增强体积分数（约60％）。压缩测试的结果表明：与传统的FW管相比，SW实现的机械特性具有较高的可重复性，SW管的纤维体积分数更高，并且机械性能得到了改善。
