木材材性退化的试验研究进展综述

Review of experimental research on wood degradation

长期的环境温湿度的交替、日光的暴晒,会对木材材性产生损伤,比如开放性干缩裂纹以及碳化等,进而对木结构的工作性能造成负面影响。针对学者在木材因环境温湿度和光照交替引起的损伤方面的试验研究进行分析,包括人工模拟实验的方法、损伤评价等级与物理力学指标等相关性研究进展,论述了该研究的重点、难点以及今后的研究方向,为进一步开展古木材老化性能的研究提供借鉴。

When the wood in the situation of the long-term corrosion by sunlight exposure of the mold and the alternate effect of environmental temperature and humidity,can produce damage on the surface,including rapid deterioration and carbide opening drying shrinkage crack.Damage will bring the wood such as degradation and other issues,which can reduce greatly affect.This paper summarizes the scholars under the action of the two wood aging working condition of the artificial simulation condition,including the method,damage rating changes in physical mechanics indexes of correlation research progress,discusses the focus in the study of the difficulties and the future research direction for further research on ancient wood aging performance.
