摘要：为促进黑木相思木材的合理开发和高效利用,对其物理和力学性质进行测定分析。结果表明:黑木相思木材的密度属中等级别,体积干缩系数属很小级;顺纹抗压强度等主要力学强度指标均属中上水平,综合强度为166.8 MPa,综合品质系数为320.2,均属很高等级。
The physical and mechanical properties of Acacia melanoxylon wood were analyzed and evaluated in order to provide reference data for optimal production and efficient utilization.The results showed that the density of the wood was classified as the medium grade,and the volumetric shrinkage coefficient was very small grade.The main mechanical properties of the wood were all in the middle and upper grade levels.The comprehensive strength of the wood was 166.8 MPa,which was classified as the very high grade.The comprehensive quality coefficient of the wood was 320.2,which was classified as the very high grade.
