Properties of flakeboards from hardwoods growing on southern pine sites

Abstract

Boards 0.5 inch thick were made from 3-inch-long flakes of 9 species of southern hardwoods commonly found on pine sites. The main effects of species were due to variation in wood density; low-density species compacted readily when pressed, and the resulting good flake contact improved bonding and gave boards of high strength. With species having specific gravities above 0.6, it was difficult to form stiff boards without increasing density unduly. In black tupelo, cross-grained flakes yielded boards of exceptionally low MOE, even though wood specific gravity was below 0.6. In white oak boards, substantial delamination occurred after a 5-hour-boil test. Within the range of the experiment, all species except white oak and post oak yielded boards of acceptable dimensional stability at board densities of 44.5 pounds per cubic foot or less.
