Wood Science and Technology Aims and scope Submit manuscript

Summary

New information is presented that concerns flexural strength and stiffness of southern pine plywood and verification of a method developed by the U. S. Forest Products Laboratory for predicting properties of plywood. This method can predict, with sufficient accuracy, properties of southern pine plywood despite the large natural variability of veneer of this species and other variables. Strength and stiffness between 3-ply and 5-ply plywood with face grain parallel to span are compared. In addition, strength and stiffness between plywood and unidirectionally laminated veneer with same number of plies and total thickness are compared.
