CONCLUSIONS
In conclusions, alignment of strands improved the bending strength and stiffness
of OSB in the direction of alignment but caused a corresponding reduction in the
direction perpendicular to the alignment under dry and wet conditions. Secondly,
alignment of face strands improved the bending strength and stiffness of OSB in the
lengthwise direction. Cross alignment of core strands also improved the bending
strength and stiffness of OSB in the widthwise direction. Thirdly, the strand orientation
has no effect on the internal bonding and thickness swelling. Finally, strand alignment
in the manufacture of OSB is advantageous in performance properties, particularly
when the panel bending parallel to strand alignment is involved.
