Properties of OSB panels with veneer inclusion
This work aimed to evaluate the effect of veneer inclusion with different wood species, and also different levels of pressing pressure applied in the moment of the veneer inclusion over physical- mechanical properties of already consolidated OSB (Oriented Strand Board) panels.
