Rotational wood welding: Mechanical properties of thermally treated oak [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2022
The paper examined the strength of rotationally welded joints between untreated beech dowels and samples of thermally modified and unmodified oak wood (used as substrates). The results were compared with the control group where beech dowels were

Electrical resistance characteristics of thermally modified wood

open access: yesEuropean Journal of Wood and Wood Products, 2022
AbstractThis paper presents electrical resistance characteristics of ThermoWood® Thermo-D Norway spruce for wood moisture content measurements below fibre saturation point. Electrical resistance along the grain of small clear wood specimens was measured at various moisture content levels of ~ 4–15% for thermally modified and ~ 5–25% for unmodified ...

Some physical characteristics of thermally modified oriental-beech wood [PDF]

open access: yesMaderas. Ciencia y Tecnología, 2014
Heat treatment of Oriental-beech (Fagus orientalis) wood was carried out by hot air in an oven for 2, 4, and 8 h at 140, 170, and 200°C. After heat treatment, some physical characteristics such as surface roughness, color, glossiness, and mass loss of Oriental-beech wood specimens were measured.Our results showed that heat treatment caused decrease in ...

Influence of Post-extraction on Photostability of Thermally Modified Scots Pine Wood during Artificial Weathering

open access: yesBioResources, 2016
The photo-stabilizing effect of post-extraction was evaluated for thermally modified wood. Extracted and non-extracted thermally modified Scots pine (Pinus sylvestris L.) samples were exposed in a xenon weather-ometer for 1008 h, and the surface color ...

Properties of some thermally modified wood species [PDF]

open access: yesMaterials & Design, 2013
Abstract The objective of the study was to investigate the influence of heat treatment and exposure time on surface roughness, wettability, shear strength and hardness of rubberwood, Eastern redcedar and red oak samples. The anatomical structure of each species was also observed using scanning electron microscope (SEM).

Thermal behaviour of modified wood fibers

open access: yesPolymer Testing, 1998
Wood-fibers were modified by silanes treatments and/or by coating with polypropylene or polystyrene. Enhancement in thermal stability of wood fibers treated with γ-aminopropyl triethoxy silane and in fibers coated with polypropylene or polystyrene are discussed. Thermoanalytical data (TGA, TMA and DSC) of the samples may aid to predict the behaviour of

Calorific Value and Chemical Properties in Juvenile and Mature Wood of Thermally-Modified Eucalyptus Grandis

open access: yesDrvna Industrija, 2016
During thermal modification, timber is exposed to temperatures approaching 200 ºC for several hours and wood properties change. This study was aimed at evaluating the calorific value and chemical properties of juvenile and mature wood of thermally ...
