The physical properties and fiber morphology of matured Acacia Mangium

The research of physical properties and fiber morphology were performed on matured Acacia mangium. Physical properties of matured A.mangium were determined by density, specific gravity and moisture content. While fiber morphology of matured A.mangium were determined by fiber length, fiber diameter, lumen diameter, cell wall thickness, runkel ratio, felting power, and coefficient of suppleness. The objectives of this study were to determine the effect of physical properties and fiber morphology of matured A.mangium from their different trunk height (top, middle, and bottom) and trunk diameter (bark, intermediate, pith). From this study, properties and fiber morphology were significantly effected along the trunk height and across the trunk diameter of matured A. mangium.
