Wood Variation and Wood Properties
1989Wood, a most useful substance, varies greatly. Wood properties are changing throughout the world (Zobel et al 1983) and the magnitude and causes of the changes must be known. The importance of wood properties to the final product is becoming better known; one example is the relationship of the morphology of loblolly pine (Pinus taeda) tracheids and the

Properties of furfurylated wood
Scandinavian Journal of Forest Research, 2004The first processes of wood modification with furfuryl alcohol (FA) (furfurylation) were developed several decades ago. FA is a renewable chemical, produced from hydrolysed biomass waste. Over the past decade modernized processes for furfurylation of wood have been developed. This study presents decay properties of furfurylated wood. Laboratory methods

Fatigue properties of wood and wood composites
International Journal of Fracture, 1980An overview of the state of fatigue research for wood and wood products is presented. The extreme lack of a satisfactory data base and the persistent neglect of fatigue characteristics in wood material design is emphasized. Some theoretical considerations are presented to point out the difficulties met when attempting to model the behavior of wood ...

Fracture Properties of Wood and Wood Composites
Advanced Engineering Materials, 2009Wood has a complex hierarchical structure and is a kind of polymeric composite with elongated cells in an amorphous matrix. Therefore, fracturing is a complicated process that is influenced by loading mode and direction, humidity, etc. Standard linear-elastic fracture mechanics methods mostly cannot sufficiently quantify fracturing, and combining ...

WOOD PROPERTIES AND EFFECT OF WOOD PROPERTIES ON THE WOOD FINISHING
2011Wood is basic raw material for furniture and joinery industries with wood structures. Wood is a biological material that has widely different properties depending on species, geographic area where the tree grew, the growth condition, size of the tree at harvest, sawing, and other manufacturing processes. Wood properties have been characterized

Ultrasonic Properties in Woods
Japanese Journal of Applied Physics, 1988Ultrasonic velocity and absorption were observed at 1∼4 MHz in nine different kinds of woods. They showed a strong anisotropic feature: the direction of growth (L) has the fastest velocity and smallest absorption; the direction perpendicular to annual rings (R) has the second; and the direction tangential to them (T) has the slowest velocity and ...

For structural applications, wood is most commonly found as either sawn timbers, lumber, or glued laminated members (glulams). In the interest of economy and to permit using wood more efficiently, increasing amounts of wood today find their way into manufactured structural materials or members such as (1) plywood, hardboard, chipboard, flakeboard ...

As a raw material (Picea abies), Norway spruce wood, has wide application as a building material and in industry, especially in northern European countries. The wood of Norway spruce is an important natural resource in Germany, Austria, Slovakia, the Czech Republic, Romania, as well as the Scandinavian countries.

This chapter is a follow up on the previous one on the anatomical and physical properties of hardwoods in general. In this chapter, therefore, the reader is introduced to the mechanical properties of wood, i.e., those properties of wood that usually require mechanical stress for their determination (excluding non-destructive test methods).

1988
It has been noted (Chap. 1.2.1.5) that two general types of electrical moisture meters have been used to estimate the moisture content of wood. These are resistance meters which measure essentially the direct current (DC) electrical resistance, and dielectric moisture meters which measure some function of the complex dielectric constant or electrical ...
