Stiffness of Douglas-fir lumber : effects of wood properties and genetics

Creator:

Vikram, Vikas

Abstract:

Wood stiffness is one of the most important properties of lumber and veneer. We studied wood stiffness (modulus of elasticity, MOE), wood density, microfibril angle, and knots in a 25 year-old wind pollinated progeny test (50 families, ~ 373 trees) of coastal Douglas-fir to understand the potential for genetically improving...

Evaluation of a prototype NIR system for Douglas-fir wood density estimation

Creator:

Belart Lengerich, Maria Francisca

Abstract:

Forest products companies in the U.S. face vigorous competition from other wood producers around the world and other industries (steel, aluminum, plastics, composites). To be competitive, forest companies need to control costs, sort and allocate logs to the most appropriate markets, and recover more value at time of harvest. Interest...

In-forest log segregation based on acoustic measurement of wood stiffness

Creator:

Amishev, Dzhamal Y.

Abstract:

To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...
