摘要
压缩变形特征是压缩木研究的重要内容。文中针对木材湿热软化径向压缩变形,从压缩变形的影响因素、压缩变形位置对其力学性能的影响和压缩变形固定3个方面综述国内外研究进展,包括树种、生长轮构造和压缩工艺对木材压缩变形的影响,压缩变形位置对力学性能的影响,以及热处理对压缩变形的影响,指出木材湿热软化径向压缩研究中关于压缩变形需要继续解决的主要问题以及发展方向,以期为湿热软化径向压缩木材的进一步研究和应用提供参考。
Compressive deformation property is an important content of the studies of compression wood. This paper summarized in detail the studies on deformation properties of radial compression wood under hydrothermal condition at home and abroad in terms of influencing factors to the compressive deformation,effects of compressive deformation position on mechanical properties and fixation of compressive deformation. The effects of species,growth ring structure and compression process on the compressive deformation as well as the effects of deformation position on mechanical properties are concluded,and the effects of heat treatment on compressive deformation are analyzed. It points out the main problems found in the research on deformation properties of radial compression wood by hydro-thermal compression and the future research direction. This paper is expected to provide references to the further study and application of radial compression wood technology under hydro-thermal condition.
