| 摘要 |
A seven-layered laminated composite lumber 1 is constructed by stacking veneers 2, whose oven-dry specific gravity is 0.6 or larger, alternately with veneers 3, whose oven-dry specific gravity is 0.4 or less, and by bonding them together. The invention can thus provide a laminated composite lumber that is light in weight, is substantially resistant to warping and distortion, and yet retains the desired bending strength and nail holding power, and a method of producing such a laminated composite lumber.
