Highlights Testing 331 fibre-managed E.nitens sawn boards to verify the normal distribution of static edgewise MoE values. Testing 147 boards in flatwise to explore the relationship between flatwise and edgewise MoE values. Visual grading 147 boards to obtain the correlation between visual features and static flatwise MoE values.
Abstract This study investigated the relationship between flatwise and edgewise modulus of elasticity (MoE) of plantation fibre-managed E. nitens sawn boards. 331 boards were used to build a complete picture of this resource by measuring the density, moisture content, and static edgewise MoE. Then, 147 boards were tested for static flatwise MoE. Results showed that average static flatwise MoE is highly linearly related to static edgewise MoE. The average flatwise MoE could be predicted through the linear relationship considering the contribution of the width of the boards. The R2 value of this linear regression formula is 0.9.
