Longitudinal tensile shear properties of polyurethane-bonded preservative-impregnated Eucalyptus grandis laminates subjected to varied simulated climatic conditions
2023 - IRG/WP 23-40967
Bonding process adaptations have yielded improvements in the adhesive bonding of Eucalyptus grandis wood for manufacturing hardwood laminates. However, there are still concerns over the adhesive-bond performance, particularly preservative-impregnated E. grandis laminates, under exposure to varying climatic conditions. These concerns could limit the implementation of E. grandis laminates, especiall...

Modification of Gmelina arborea wood for utilization in Nigeria
2023 - IRG/WP 23-40986
The level of protection achieved by any wood treatment process is dependent on achieving a sufficient uptake and penetration of the treatment chemicals. This phenomenon is also applicable when considering chemical modification of any wood species. The desired changes in physical, mechanical or durability enhancement of treated species can only be achieved beyond a superficial treatment. For this, ...

Intra-species variability of moisture dynamics in wood
2024 - IRG/WP 24-11040
Moisture dynamics of wood and wood-based materials play a major role in wood durability against different decay organisms. Their impact becomes particularly evident when wood is exposed, but not permanently wet. To date, however, this has only been taken into account indirectly and therefore inadequately when testing the durability of wood. While test methods are available, for example to determin...

International joint field trial on the moisture performance of wood – Set up and first results
2024 - IRG/WP 24-40996
Wood durability to decay stems from its inherent resistance to fungi resistance to fungi. In this regard, wood's ability to withstand moisture uptake plays an important role as the lower threshold for wood decay is a moisture content of 25%. However, the aspect of moisture resistance is not yet sufficiently emphasized as a durability factor, both in the assessment of durability as a material prope...
