Identification of chemical and mechanical changes in thermomechanically compressed alder wood

Abstract

The article presents the results of thermogravimetric analysis, IR spectroscopy, and microscopic examination of the densified alder wood. Purpose of the research was the identification of chemical and mechanical changes resulting from its piezothermal treatment. The results of thermogravimetric analysis were used to execute substantiation changes in wood properties during compaction. The obtained results allowed to choose the criterion for assessing the degree of wood plastification.
