Effect of Molding Temperature on the Strength and Dimensional Stability of Hardboards from Fiberized Water-Soaked Douglas-Fir Chips
Strong hardboard was made from stock prepared by fiberizing water-soaked Douglas-fir chips. The hardboard was made without resorting to steam-cooking, the incorporation of synthetic resins, or prolonged heat treatment of […]

Effect of Particle Geometry on Properties of Molded Wood-Resin Blends
This study shows that particles reduced by hammermilling reflect the geometry of their parent particles down to approximately 80 mesh in size. Stick-like particles, such as those obtained from hammermilled […]

Effect of Prefreezing on the Perpendicular-To-Grain Creep of First-Dried Redwood
The effect of prefreezing on dimensional change was determined for 0.200-inch-thick flatsawn and quartersawn samples loaded perpendicular to the grain during drying at either 100?F or 160?F. Prefreezing reduced shrinkage […]

Effect of Reversing the Loose and Tight Sides of Surface Veneer on Flexural and Shear Properties of Southern Pine Plywood
Placing the loose side of face veneers outside has only a small effect on the stiffness of uncycled southern pine plywood. However, the effect (reduction) could be 10 percent or […]
