Abstract

Evaluating the wood quality of plantation forests is necessary to determine the suitability of the raw material for corresponding products. This study was conducted to evaluate some physical and mechanical wood properties of 5-year-old Michelia tonkinensis planted in Dong Hy district, Thai Nguyen province. Sample trees were collected and then processed into standard test specimens to measure wood density, modulus of rupture, and modulus of elasticity at 12% moisture content. The results showed that the average values of wood density, modulus of rupture, and modulus of elasticity were 0.44 g/cm³, 49.10 MPa, and 3.50 GPa, respectively. Wood density was found to be a good indicator for predicting the modulus of rupture of M. tonkinensis wood. The mechanical properties of M. tonkinensis wood in this study are low, therefore, it should be used as raw material for engineered wood, pulp, interior decoration, or the M. tonkinensis forests should continue to be tended and maintained to enhance their mechanical properties.
