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...

Prevention of termite tubing on foam insulation materials
2024 - IRG/WP 24-11039
Foam insulation products have been shown to be damaged by termites who can readily tunnel within it and use it as a conduit within structures. Different types of commercially available foam insulation were tested to see if they could support termite (Coptotermes formosanus, Shiraki) tunnelling on or within them and whether they could be used as a conduit to access a wood food source placed above i...

The durability and mechanical properties of 40 years old Black locust poles
2024 - IRG/WP 24-11042
This study investigates the durability and mechanical properties of 40-year-old black locust (Robinia pseudoacacia) poles harvested from a vineyard in Slovenia. Wood from these poles was compared to recently harvested black locust wood to determine possible reuse options. Visual inspection, hyperspectral imaging, and laboratory tests were conducted to assess decay, density, mechanical properties, ...
