Predicting Modulus of Elasticity for Wood-Based Composites

Abstract:

Article Preview

The modulus of elasticity of wood, fiberboard and wood-fiberboard composite was measured by nondestructive test (longitudinal transmission vibration method). The predicting model of the modulus of elasticity of wood-fiberboard composite was discussed. This study has shown that the wood ratio has substantial effect on the modulus of elasticity of wood-fiberboard composite. The modulus of elasticity of wood-fiberboard composite can be predicted from volume fraction of wood by simulation formula. The model Eq.(3) can be used to predict the modulus of elasticity of the wood-fiberboard composite from the modulus of elasticity and volume fraction of wood and fiberboard when M=0.92~0.97. The model Eq.(4) can be used to predict the modulus of elasticity of the wood-fiberboard composite from the modulus of elasticity and volume fraction of wood and fiberboard when M=0.97~0.99.
