Main Forms of Outdoor Deterioration of Bamboo Timber and Its Research Prospects
Bamboo and its products are susceptible to deterioration caused by a variety of factors during application,resulting in reduced performance and shortened service life.At present,the research on aging,mildew,and decay of bamboo has made certain achievements.However,the deterioration of bamboo properties and degradation mechanism under the combined effect of multiple deterioration factors are less studied.In this paper,the changes of bamboo timber in physical and mechanical properties,chemical composition,and microstructural of bamboo during the process of photoaging,moisture-heat aging,mildew,and decay are reviewed,and the interactions between the different forms of deterioration are elaborated.On this basis,the future research and development direction of the bamboo deterioration is proposed,in order to provide a theoretical reference for the conservation and utilization of bamboo.
