Correlation between fibre length characteristics and mechanical properties of Tectona grandis wood
Article Main
Abstract
This study considered the relationship between fibre length characteristics and mechanical properties of Tectona grandis wood aged 15, 20 and 25-year. Six trees of even aged and similar class diameter were used for the study. Wood samples used for the study were systematically collected from three portions at 10, 50 and 90% of the tree height. The test samples were prepared along the radial positions from the pith to the bark. The relationship between fibre length and mechanical properties were examined using linear regression models and correlation coefficient. The results obtained from the correlation analysis carried out to examine the linear relationship between fibre length and mechanical properties of T. grandis wood were 0.924, 0.929 and 0.940 for MOR, MOE and CS parallel to grain. The relationship was highly significant (p < 0.05). Also the correlation coefficient (r) between fibre length and mechanical properties of T. grandis wood were highly significant (p < 0.001). Therefore, fibre length characteristics can be used as an index in predicting the mechanical properties of T. grandis wood.
