Durability of a willow/plastic composite mat
2016 - IRG/WP 16-20592
Developing uses for wood wastes could enhance utilization of low value renewable materials while creating opportunities for rural development. Small diameter willow stems have little use in China, but they could be combined with high density polyethylene to create wood plastic composite mats for decorative applications. These mats could be used in exterior, above ground exposures, but would still ...

Monitoring Diversity and Colonization Patterns of Wood-Inhabiting Fungi Using Field Stake Tests
2017 - IRG/WP 17-20614
Advances in molecular identification of microbial communities enabling rapid microorganism determination have allowed ecological data to be increasingly incorporated into standardized wood performance tests. Combining standard field tests with molecular methods to study wood-associated microflora can help to better understand fungal colonization and decay processes of wood in service. The potentia...

Boron dual-treatments for Douglas-fir utility poles: Tracking boron migration over time
2019 - IRG/WP 19-30739
The potential for using boron pressure-treatment prior to over-treatment with conventional, heavy-duty wood preservatives to limit internal decay in-service was investigated in two field tests on Douglas-fir utility poles. Pole sections were pressure-treated with disodium octaborate tetrahydrate (DOT) and then over-treated with either pentachlorophenol or copper naphthenate in oil. Alternatively, ...

Sterilization of Large Timbers during Preservative Treatment: How Quickly We Forget
2020 - IRG/WP 20-40902
Air seasoning is a common method of moisture management in utility poles and is done de facto during pole storage prior to treatment. However, extended air drying prior to treatment encourages fungal attack and can facilitate establishment of decay fungi in poles before a protective preservative barrier is applied. This problem can be mitigated by proper air-seasoning methods coupled with heat ste...

Durability of thermally modified western hemlock lumber against wood decay fungi
2022 - IRG/WP 22-40954
The chemical modification of wood is gaining popularity as a treatment to increase wood durability in the United States. Further standardization and testing of thermally modified North American species is needed to optimize the production of thermally modified products from regionally available resources. This work measures the impact of thermal modification of western hemlock lumber durability ag...
