RELATING WOOD CHEMISTRY AND STRENGTH: PART II. FUNDAMENTAL RELATIONSHIPS BETWEEN CHANGES IN WOOD CHEMISTRY AND STRENGTH OF WOOD
Keywords:Keywords, Chemistry, Mechanical Properties, Decay, Treatments, Thermal Effects
In Part I of this series, the relationship between physical properties and chemistry andanatomy of wood were reviewed (Winandy 2016). This Part II article explores a fundamental relationship between the mechanical properties and the chemical composition of wood and how degradation of its individual chemical components affects strength loss. It then presents a proposal for a universal theory as to the fundamental mechanism between wood strength loss and changing wood chemistry. That theory purports that the desequencing of the complex lignocellulosic structure of woody materials involves the same systematic series of processes during either biological, chemical, or thermal deterioration. The goal of this article is to create a better understanding of how changes in wood chemistry fundamentallyinfluence wood strength.
