Shiny Beech Wood is Confirmed as an Indicator of Tension Wood

IAWA Journal, 2008
This study sought to develop a method to quantify tension wood areas in stem discs. It was suggested that the shiny appearance of beech (Fagus sylvatica L.) could provide an indication of tension wood. Each of 21 stem discs were digitised and the images analysed.

Thermopower of beech wood biocarbon

Physics of the Solid State, 2011
This paper reports on measurements of the thermopower S of high-porosity samples of beech wood biocarbon with micron-sized sap pores aligned with the tree growth direction. The measurements have been performed in the temperature range 5–300 K. The samples have been fabricated by pyrolysis of beech wood in an argon flow at different carbonization ...

Silylation of solid beech wood

Wood Science and Technology, 2001
This report presents a new derivative from the chemical conversion of hardwood. Silylation of hardwood was successfully achieved using trimethylsilyl chloride with pyridine as base. The new wood compounds were analyzed by FTIR spectroscopy. The FTIR spectra of the silylated wood compounds show new absorption bands derived from trimethylsilyl ether ...

Short-time procedure for fatigue assessment of beech wood and adhesively bonded beech wood joints

Materials and Structures, 2015
Timber as a structural material has experienced a revival for aspects related to sustainability, positive effect on interior building and increased architectural possibilities. To overcome a series of limitations related to partly obsolete traditional techniques, timber engineering sets high expectations on adhesive bonding as a joining method ...

Machining properties of thermally modified beech- wood compared to steamed beech-wood

2009
The objective of this paper was to determine and compare machining properties of thermally modified and steamed beech-wood (Fagus silvatica L.). Analysis was made of the influence of feed speed, rake angle and wood treatment on chips properties (particle size distribution, bulk density and factor of looseness), machining power and noise emission ...
