The quality of veneer from Schizolobium amazonicum was evaluated assessing physical (density, porosity, moisture content and dimensional stability), mechanical (bending strength and shear strength), nondestructive (stress wave), chemical and surface (image analysis, color, roughness and wettability) properties. The results indicated that the Schizolobium amazonicum veneer presented whitish-gray color, low density, high porosity, low dimensional stability, low roughness and high wettability. The stress wave dynamic modulus of elasticity and veneer density were significantly correlated with the mechanical properties of the veneer. These parameters can be used as indicators for assembling strategies in the manufacturing of laminated composites.
