Physical and Mechanical Properties of Albizia odoratissima Wood
In order to provide references for comprehensive utilization of Albizia odoratissima woods,main phys-ical and mechanical properties of 25-year-old A.odoratissima wood were tested.Results showed that means of basic density,air-dry density and oven-dry density were 0.635,0.761 and 0.727 g/cm3 respectively.Means of tangential,radial and volume shrinkage rates of air-dry wood were 1.53%,2.06%and 3.72%respectively,with differential dry shrinkage of 1.35.Means of tangential,radial and volume shrinkage rates of oven-dry wood were 2.92%,5.09%and 8.10%respectively,with differential dry shrinkage of 1.74.Means of tangential,radial and volume shrinkage coefficients were 0.114%,0.272%and 0.395%respectively.Means of end face hardness,radial face hardness and tangential face hardness were 6 655,4 968 and 5 218 N.Means of bending strength,bending elastic modulus,compressive strength parallel to grain and impact toughness were 136.7 MPa,12 820 MPa,70.1 MPa and 100 kJ/m2.Comprehensive quality coefficient of wood was 3 256.3×105 Pa.A.odoratissima wood had moderate dry shrinkage uniformity and better dimensional stability.A.odoratissima wood had moder-ate rigidity,relatively high density,hardness,toughness and quality as well as bending strength and compres-sive strength parallel to grain.A.odoratissima wood was excellent material for high-grade furniture.
