N2 - This study used a vibration test method to show that grain angles of face veneer have substantial effects on sound velocities and dynamic Young's moduli of three types of wood-based composites. The sound velocity at 0° grain angle of face veneer was the highest, and it decreased with increasing grain angle in the range of 0° to 90°. This tendency was similar to that for dynamic Young's modulus. The relationship between the grain angle of face veneer and the sound velocity of three types of wood-based composites can be expressed in the form of Hankinson's equation or a second-order parabolic equation. This study also showed that the application of orthotropic elasticity theory was valid for the three types of wood-based composites. The relationship between the grain angle of the face veneer and the Young's modulus of three types of wood-based composites can be expressed in the form of the Jenkin equation, Hankinson's equation, or a second-order parabolic equation. Rule of mixture can also be used to predict the Young's modulus of wood-based composite from the Young's moduli of the two elements.
