中文摘要:
      木材是一种多尺度且高度各向异性的非均质天然高分子复合材料,其力学性能取决于各个尺度的物理结构和化学组成。木材多尺度界面结构对木材的载荷传递和应力分散有重要的影响。本文从毫米级的生长轮结构到纳米级的高分子结构,总结了木材多尺度界面与其力学性能之间的内在关系,以期有助于揭示木材界面结构的应力变化、分布与传递的内在规律,并为木材加工改性与高效利用提供科学依据。
Abstract:
      Wood is a heterogeneous natural composite material with a multi-scale structure and high anisotropy, and its mechanical properties are related to the physical structure at various scales and chemical compositions. The multi-scale interface structure of wood has significant influences on its load transfer and stress dispersion. In this review, the internal relationship between wood multi-scale interface structures and its mechanical properties was summarized from millimeter-scale growth ring structure to nano-scale polymer structure, which would help to reveal the law of the stress change, distribution, and transfer of interface structures, and could provide a scientific basis for processing and modification as well as efficient use of wood.
