Dielectric properties of defects on wood surfaces

Creator:

Forrer, Johannes B.

Abstract:

Raw material costs and limited material availability and quality have created significant interest in and opportunities for the application of nondestructive evaluation techniques to improve wood processing technologies. The incentives come from the desire to 1) manufacture the highest valued product, 2) conserve the amount of raw material used, 3)...

DOUBLE RESONANT TECHNIQUE FOR THE MEASUREMENT OF DIELECTRIC PROPERTIES OF WOOD 127 Appendix 2 DIELECTRIC
Performance analysis of the hardware and software components of an optical scanning system for monitoring lumber sizes

Creator:

Leavengood, Scott A.

Abstract:

In recent years, the forest products industry has been forced to cope with a supply of raw material that is declining in both quality and quantity. In addition, log prices are escalating rapidly. Because log costs may represent as much as 90 percent of the overall production costs of lumber...

Influence of veneer roughness, lathe check, and annual ring characteristics on glue-bond performance of Douglas-fir plywood

Creator:

DeVallance, David B.

Abstract:

Current lathe technology, smaller diameter logs, smaller core diameters, and the sale of higher grade veneer for use in engineered wood products are all factors contributing to plywood manufacturers using rougher veneer with different lathe check characteristics. When rough veneer is encountered, plywood manufacturers typically increase the adhesive spread rate...
