Forest Management on Mechanical Properties of Oriented Strand Board

The goal of this study was to integrate forest management practice with the mechanical properties of oriented strand board (OSB). Modulus of elasticity (MOE), modulus of rupture (MOR), and internal bond strength (IBS) were determined from OSB panels made from control, thinned, and fertilized trees. Different trends were associated with growth ring counts and heights of the feedstock trees. The mechanical properties were not dependent on the density profiles. MOE and IBS from the different forest managed trees were strongly correlated with different anatomical structures. However, the MOR of panels made trees from different forest management schemes was not strongly correlated with any anatomical structures but was strongly correlated with MOE.
