Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...

Durability of Malaysian plybamboo to mold
2024 - IRG/WP 24-41014
Durability of 3-layer plybamboo fabricated from two Malaysian bamboo species, Gigantochloa levis (beting) and Gigantochloa scortechinii (semantan) using three different adhesives - urea formaldehyde (UF), melamine urea formaldehyde (MUF) and phenol resorcinal formaldehyde (PRF) was evaluated in this study. Samples were exposed to the mold, Aspergillus brasiliensis for 4-week following the ASTM D44...
