Revealing the degradation process of Moso bamboo (Phyllostachys edulis) by different decay fungi
2025 - IRG/WP 25-11060
Moso Bamboo (Phyllostachys edulis) is the main bamboo species for engineering; however, it is highly susceptible to various fungi during use. In this study, four prevalent decay fungi, including two brown rot fungi and two white-rot fungi, were used as the test fungi to investigate the changes in structure and chemical composition of Moso bamboo samples at different incubation times in order to be...

Multifactorial analysis of the reasons behind wood natural durability
2025 - IRG/WP 25-11065
Physical, chemical and biological properties of several wood species were investigated in order to highlight the main factors involved in wood natural durability and wood characteristic using a principal component analysis. Interaction of wood with water were evaluated using contact angle measurements to determinate wood wettability by water and wood impregnability tests with water allowing to cal...

Securing Flame Retardancy in Wood: Durability After Artificial and Natural Weathering Test
2025 - IRG/WP 25-20738
The outdoor use of wood is often limited by challenges such as dimensional instability, vulnerability to fungal decay, and high flammability. Traditional flame retardant treatments improve fire resistance but suffer from significant leaching under environmental exposure, reducing their long-term effectiveness. This study introduces an innovative solution by integrating flame retardants with DMDHEU...

Potential co-valorization of pyrolysis tars from five wood species form Tunisia as wood preservatives bases: Chemical compositions, antifungal and anti-termite activities
2025 - IRG/WP 25-20739
The pyrolysis of five Tunisian wood species (Ceratonia siliqua, Eucalyptus camaldulensis, Eucalyptus maidenii, Pinus pinea, and Quercus canariensis) was carried out in a custom-designed carbonisation reactor developed at the INRGREF's Wood Technology Section (Tunis, Tunisia). This process aimed to produce both char and pyrolysis by-products, particularly pyrolysis oils. The experiments were conduc...

The Impact of Drying Techniques on the Quality of Thermally Modified Wood
2025 - IRG/WP 25-30813
The wood drying technique applied before loading the dry wood into the ThermoWood® kiln may affect its properties. For this purpose, Scots pine (Pinus sylvestris) boards were first dried through three drying methods, including radio-frequency/vacuum (RF/V), mild, and moderate conventional drying, and then loaded into a ThermoWood® kiln for thermal modification at 212 °C for 3 hours according to...

Enhanced Termite Resistance of Low Durability Fast Growing Teak Wood by Non-Biocide Treatments Based on Chemical and Thermal Modification
2025 - IRG/WP 25-30818
Short rotation teak as a fast-growing tree can be considered as a renewable material resource for the future green economy. However, short rotation teak wood is susceptible to biodeterioration, particularly to termite attack. The objective of this work was to investigate the effect of chemical and thermal treatment on resistance of sapwood, transition wood, and heartwood of short rotation teak aga...

Enhancing strength, fire and biological resistance of wood through structural and chemical modification
2025 - IRG/WP 25-30831
Wood, a renewable and versatile biopolymer, has been a fundamental material to construct traditional and advanced composites for building construction, furniture, transparent composites, and various other applications. Despite its many advantages, including its aesthetic appeal, workability, and relatively low cost, wood possesses inherent limitations such as susceptibility to biological, flame an...

Probing nanoscale protection mechanisms with x-rays and neutrons
2025 - IRG/WP 25-11083
While it is known that exposing wood to high levels of moisture, fire, or decay agents such as fungi can be detrimental for its performance, what is often missing in literature is a holistic understanding of how wood nanostructure changes due to these exposures. This is of particular interest since treatments that are meant to impart resistance can alter these length scales and/or modify their hyg...
