Zusammenfassung: | To provide a woody laminated board having high strength and excellent dimension stability, and further improved in surface nature.SOLUTION: A woody laminated board A in which a first woody material layer B, and second woody material layers C laminated on both surfaces thereof are integrated is such that: in the first woody material layer B, a large number of first woody small thin pieces having front and rear surfaces along a fiber direction are laminated in an aggregation state and integrally bonded; the first woody small thin piece has a thickness of 0.05-0.35 mm, a fiber direction size along the fiber direction is 40 mm or less, and a fiber orthogonal direction size along a direction orthogonal to the fiber direction of 40 mm or less; in the second woody material layer C, a large number of second woody small thin pieces having front and rear surfaces along the fiber direction are laminated in an aggregation state and integrally bonded; and the second woody small thin piece is smaller than the first woody small thin piece.SELECTED DRAWING: Figure 1
【課題】高強度で寸法安定性に優れ、表面性がさらに向上した、木質積層ボードを提供する。【解決手段】木質積層ボードAは第1木質材層Bとその両面に積層された第2木質材層Cとが一体化されてなり、第1木質材層Bは繊維方向に沿った表裏面を有する多数の第1木質小薄片が集合状態で積層されて接着一体化され、第1木質小薄片は厚さが0.05~0.35mm、繊維方向に沿った繊維方向寸法が40mm以下、繊維方向と直交する方向に沿った繊維直交方向寸法が40mm以下であり、第2木質材層Cは繊維方向に沿った表裏面を有する多数の第2木質小薄片が集合状態で積層されて接着一体化され、第2木質小薄片は第1木質小薄片よりも小さい。【選択図】図1 |
