Synopsis

The main purpose of this study is to provide the knowledge and data on the physical, mechanical and nanostructural properties of Acacia mangium wood from Sabah. A further objective was to examine the influence of microfibril angle (MFA) on strength, stiffness, tree age, the distance from pith to bark and the internal structure of the wood and to predict the perfect growth age which produces pure crystalline cellulose and more ordered. The results show that the fully grown which produce fully crystalline cellulose will denote as the optimum age (ao) was found to be 23.45 year for the pith region, ao was about 23.29 year for the bark region and for the pith - bark region about 22.04 ± 0.05 year. The mean length of cellulose crystalline ranged from 3.86 Å in the 3-year-old disc to 23.43 Å in the pith region of 15-year-old disc. MFA was found to decrease whilst tree age increased for the pith and bark regions. The general trend was for the MFA to be greatest in the young wood of age 3-year-old about 26.13°, and to decrease gradually with increasing the tree age. The lowest was found in the pith region of tree at 15-year-old where the angle varied from 1.99° to 0.20°. Small-Angle x
