Research Progress in Influencing Factors to Wood Deformation and Cracking and Anti-cracking Measures
As a renewable and recyclable green material,wood has been widely used in the fields of furniture,construction,etc.In recent years,with the intensified conflicts between the supply and the demand of timber,the efficient use of timber resources has become a research hotspot.However,deformation and cracking caused by structure and internal stress of wood heavily affect its service life and application value.Therefore,it is important to study the causes of wood deformation and cracking as well as the anti-cracking measures.This paper discusses the causes of wood deformation and cracking from the perspectives of microstructure,macrostructure,growth stress,and drying stress,and summarizes the research progress in anti-cracking measures for wood,including heat treatments,filling treatments,and chemical modifications.At the end,this paper presents the future research directions,with the aim to further clarify the mechanisms behind wood deformation and cracking and to provide a theoretical basis of and the scientific solution to wood deformation and cracking encountered in production.
