| Abstract: | 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 hydro-thermal 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. |
