Interaction of Boultonizing and through-boring of Douglas fir sapwood
2018 - IRG/WP 18-40833
The interaction of combining through-boring and Boultonizing treatment effects on strength properties was investigated. Small, clear Douglas fir beams were through-bored and/or Boultonized in full factorial design and evaluated for toughness, MOE and MOR. The simulated through-boring treatment lowered the mechanical properties but the Boultonizing process did not. There was also no evidence for a ...

Influence of weathering on the mechanical properties and performance of exterior wood coatings
2022 - IRG/WP 22-40951
Three commercial coatings were exposed to artificial (EN 927-6) and natural weathering (EN 927-3) on wood samples. Cracking was visually assessed as well as Persoz hardness. Free films of the same coatings were also exposed to the same weathering tests before their tensile properties were measured. Results show that artificial and natural weathering modified the overall mechanical properties of wo...

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...
