Wood laminate material and method for manufacturing same

Abstract

Provided is a strand board with improved strength and water resistance. Reduction in productivity is prevented and characteristics of the strand board can be varied as desired while achieving certain strength and water resistance of the strand board. A strand board B is formed by stacking and laminating five strand layers 1 each formed by a large number of strands 5. The strand board B has substantially constant density distribution in the lamination direction of the strand layers 1. Three of the five strand layers 1 of the strand board B are high-density strand layers 1a having a higher density than the other strand layers 1, and the other strand layers 1 are low-density strand layers 1b.

         5 . A wood laminate material formed by stacking and laminating multiple woodbased material layers each formed by laminated woodbased materials that are laminated multiple cut pieces or a woodbased material that is a veneer, wherein
 the multiple woodbased material layers include at least one high-density woodbased material layer, the remainder of the multiple woodbased material layers is a low-density woodbased material layer, and the high-density woodbased material layer has a higher density than the low-density woodbased material layer, and   the woodbased material layers located at both ends in the lamination direction of the woodbased material layers are the high-density woodbased material layers.

         13 . A method for manufacturing a wood laminate material, comprising:
 a stacking step of stacking multiple woodbased materials, which are cut pieces or veneers, to form multiple woodbased material layers so that at least one of the multiple woodbased material layers is formed by a high-density woodbased material or high-density woodbased materials having a relatively higher density than the remainder of the woodbased material layers; and   a forming step of compressing or compacting the multiple woodbased material layers formed in the stacking step.
