3D Microstructure Reconstruction of Bamboo Fiber and Parenchyma Cell

ABSTRACT

Synchrotron radiation absorption based and phase-contrast X-ray tomographic microscopy techniques are applied for observation and identification of the 3D features of bamboo fiber and parenchyma cells at micro-scale. The results revealed the 3D features within the fiber-reinforced bamboo. As to the 3D microstructure, the fiber and the parenchyma cells matrix are reconstructed, respectively. The 3D reconstruction will reveal necessary 3D geometrical and material parameters for better understanding the mechanical and biological functions of bamboo and provide new research ideas for relevant mechanism and the design of hierarchical structure of composite material.

摘要

采用基于同步辐射吸收和相位衬度的x射线断层显微术，对竹纤维和薄壁细胞的三维形貌进行了微观观察和识别. 结果揭示了纤维增强竹纤维内部的三维特征. 在三维结构方面，分别重建了纤维和薄壁细胞基质. 三维重建将揭示竹子所需的三维几何和材料参数，为更好地理解竹子的力学和生物学功能，为复合材料的相关机理和层次结构设计提供新的研究思路.
