Beech wood impregnation with hydrolyzed wattle tannin [PDF]
BioResources, 2021 Tannins and their toxic effects against various decay organisms have been interrelated for centuries. As natural products have gained more interest, waste from several production fields abundant in tannins has yielded promising components for wood preservation.

Decay Resistance of Weathered Beech Wood
Journal of Anatolian Environmental and Animal Sciences, 2020 Wood is susceptible to photo-degradation in outdoor applications, and deformations occur on its surface such as micro or macro cracks, color changes etc. Especially, cracks make wood material more vulnerable to biotic attacks. In this study, decay resistance of natural and accelerated weathered beech samples was investigated by a brown (Coniophora ...

Effect of Feed Speed and Wood Species on Roughness of Machined Surface [PDF]
Drvna Industrija, 2009 In this study, the surface roughness values of planed beech-wood (Fagus L.), oak-wood (Quercus L.) and fir-wood (Abies alba Mill.) specimens were examined. The samples of beech-wood were cut from steamed beech-wood and from thermally modified beech-wood (

Identification and comparison of oil compounds derived from pyrolysis of sound wood and decayed wood of beech by using Gas Chromatography and Mass Spectrometry (GC/MS) [PDF]
تحقیقات علوم چوب و کاغذ ایران, 2015 Among the forest diseases, fungi are the most important factors that cause irreparable losses to the wood in standing trees and logs. Fungi are the cause of contamination and decay of trees and timbers in forest or in the stock of factories.

Pore space analysis of beech wood: The vessel network [PDF]
Holzforschung, 2010 AbstractWater transport in wood is vital for the survival of trees. With synchrotron radiation X-ray tomographic microscopy (SRXTM), it has become possible to characterize and quantify the three-dimensional (3D) network formed by vessels that are responsible for longitudinal transport.

Impact Bending Strength and Brinell Hardness of Densified Hardwoods
BioResources, 2016 The objective of this research was to determine the influence of wood species (Fagus sylvatica L. and Populus tremula L.), thickness (4, 6, 10, 18 mm), and degree of densification (0%, 10%, and 20%) on the impact bending strength (IBS) and Brinell ...

Hardness of thermally modified beech wood and hornbeam wood
Šumarski list, 2019 There is increasing number of products made of termally modified wood (mainly floor coverings) in wood market. Thermal modification at temperatures above 160 °C in oxygen free environment is known to alter the physical and mechanical properties of wood, among others.
