Failure characteristics of thermally modified poplar wood subjected to mechanical tests
2023 - IRG/WP 23-40983
Poplar (Populus spp.) are among the fastest growing timber species and have been widely planted for use in plywood, composites, pallets, furniture components and paper production. However, the low density of the wood limits many structural applications and the wood has little resistance to biodegradation. Thermal modification represents one approach to improving durability by changing the moistur...

Process Development in Continuous Wood Densification and the Influence of Ionic Liquids on Set-Recovery and Mechanical Properties
2025 - IRG/WP 25-30827
The densification of wood significantly enhances its mechanical properties, making low-density species more viable for high-performance applications. However, challenges such as set-recovery (SR) and production speed hinder large-scale adoption. This study investigates continuous surface densification using a custom-built belt press and examines the effect of chemical pre-treatment with ionic liqu...
