Book Description
The dielectric constant and loss tangent of white oak, Douglas-fir, and four commercial hardboards were measured at frequencies from 20 Hertz(Hz) to 50 Megahertz(MHz), moisture conditions from ovendry to complete saturation, temperatures from -20 to +90C., and, for the natural wood, with the electric field alined with three principal structural orientations. The hardboard was measured with the electric field perpendicular to the faces of the board. The behavior of all materials studied was qualitatively similar. The dielectric constant increased with increasing moisture content or temperature, and decreased with increasing frequency.

Book Description
Provided here is a comprehensive treatise on all aspects of dielectric properties of wood and wood products. The topics covered include: Interaction between electromagnetic field and wood. - Wood composition and dielectric properties of its components. - Measurement of dielectric parameters of wood.- Dielectric properties of oven-dry wood. - Dielectric properties of moist wood. - Effect of different kinds of treatment on dielectric properties of wood. - Dielectric properties of bark. - Dielectric properties of wood-based materials. - Recommendations for determination of dielectric parameters of wood based materials and for their use in calculations. Several appendices comprise reference data onthe dielectric characteristics of wood and wood-based materials in the wide range of frequencies, temperatures, and moisture content.

Book Description
To achieve full utilization of each harvested tree, interest centers on use of all of the tree components. The objective of the study is to determine the influence of the morphological characteristics of pulp fiber from 12 western U.S. softwood species, representative of a wide range of fiber. The effect of the morphology of the wood pulp fiber as distinguished from that of the wood fiber is emphasized because differences in performance of fiber-based products are traced to the pulp fiber. Interrelationships of fiber morphology and pulp sheet properties are discussed. The results indicate that it is not possible to fully characterize the performance of a pulp by a single morphological characteristic and that the morphological characteristics significantly influence strength properties of sheets.
