Heat treatment, thermal treatment, thermal degradation of wood, carbon nanotubes and Damascus steel swords. What do they all have in common?
2008 - IRG/WP 08-40399
Thermal degradation of wood is a well known phenomenon. Yet heat-treatment of wood can also provide protection for wood against certain environmental hazards. This paper explores some of the aspects of thermal degradation of wood fiber at relatively low temperatures with a surprising result. Carbon nanotubes (CNTs) were produced when a specific heating regime was used to carbonize the wood fiber. ...

Grading the Performance of 18 Common Bamboo Species
2010 - IRG/WP 10-10723
A grading method for assessing the performance of 18 common bamboo species was introduced in this article. The method was based on 4 grade levels with corresponding scores of 4 reference indexes of bamboos including culm diameter, culm-wall thickness, natural durabiliy and preservative treatability. In comparison with the traditional utlilization of bamboo, the grading results showed that this gra...

Long term durability of the heartwood of seven common softwood species in above ground conditions
2012 - IRG/WP 12-10771
The natural durability for wood in above ground use has been evaluated based on results after 11 years of exposure in a test site situated at the Danish Technological Institute in Taastrup, Denmark. Selected results for seven common softwood species exposed horizontally are reported. The test results cover samples with direct rain exposure (use class 3 of the European standard EN335-1:2006) and sa...

Use of Acoustic Emission (AE) to detect activity of common European dry-woodboring insects: some practical considerations
2013 - IRG/WP 13-10803
Old house borer (Hylotrupes bajulus), Furniture beetle (Anobium punctatum), and Deathwatch beetle (Xestobium rufovillosum) are common dry-woodboring insects occurring throughout Europe. With the aim to prevent unnecessary use of biocidal products, to protect valuable wooden elements and objects from unwanted influences, and to have a more objective method, SHR has started to study the use of acous...

Comparison of moisture loss and its increment during the rehearsal process based on natural drying and water soaking application with or without sealing the trial discs of Common black poplar (Populus nigra L.)
2013 - IRG/WP 13-40639
This study was subjected to be set up to prove the pattern of moisture loss and moisture increment within the same wood samples prepared as the discs (30x23±3 cm diameter) with or without the bark intact during drying and in the duration of the water soaking application. In this concept, wood was exemplified by Common black poplar (Populus nigra L.) of the five 12 year old trees that are grown in...

Evaluation of vessel features on physical and mechanical properties of wood of Common black poplar (Populus nigra L.) grown at different elevations in the region with a continental climate
2014 - IRG/WP 14-40656
This study essentially examined the effect of elevation on the anatomical structure, and the physical and mechanical properties of Common black poplar (Populus nigra L.) wood. The scope of the study was to observe the variability of vessel element features on physical and mechanical properties of Common black poplar (Populus nigra L.) in relation to habitat at different elevations. For this purpos...
