Improvement of short rotation teak wood properties through thermal modification
2018 - IRG/WP 18-40842
Teak (Tectona grandis L.f) is one of the most popular tropical timber species. Nowadays, the source of long rotation teak is limited in the availability. Many wood processing industries use short rotation teak, which has lower quality especially in durability and dimensional stability. Heat treatment is an eco-friendly method improving dimensional stability and durability of wood. The objectives o...

The effect of sapwood and heartwood differences on durability of short rotation teak wood
2022 - IRG/WP 22-10991
Short rotation teak has been developed to overcome the limited supply of long rotation teak. The aim of this study was to investigate the effect of sapwood and heartwood differences on durability of short rotation teak. The following basic properties were studied: extractive content, dimensional stability (volumetric swelling and water uptake), decay resistance, and termite resistance. The result...

The influence of chemical and thermal modification on homogeneity between sapwood, heartwood, and transition wood of short rotation teak
2023 - IRG/WP 23-40961
Short rotation teak wood has low quality especially in durability. Heartwood presents sufficient natural durability and poor impregnability; meanwhile, most sapwood requires special treatment to increase its durability. The objective of this work was to investigate the effect of thermal or chemical treatment on homogenization between sapwood, heartwood, and transition wood for some selected proper...
