为了解黑黄檀木材的基础材性,以云南西双版纳的黑黄檀为研究对象,进行了主要物理和力学性质的测定和分析。结果表明,黑黄檀木材属高密度等级材,全干体积干缩系数小;顺纹抗压强度、抗弯强度、冲击韧性分别为60。13 Mpa、126。4 Mpa、80。82 kJ·m-2,对应强度等级分别为4级、4级、2级;端面、弦面和径面的硬度分别为105。38 Mpa、85。12 Mpa和87。15Mpa,其中端面和弦面硬度属很硬等级,为高硬度木材;木材的综合强度为186。53 Mpa,属高强度树种;木材的品质系数达277。83 MPa,属于高等级材。
Physical and mechanical properties of Dalbergia fusca wood
In order to develop and utilize Dalbergia fusca wood reasonably,the main physical and mechanical properties of the wood were measured and analyzed.The results showed that Dalbergia fusca wood was a high-density wood with small shrinkage coefficient of the total dry volume.The compressive strength,bending strength and impact toughness were 60.13 Mpa,126.4 Mpa and 80.8 2 kJ·m-2 respectively,and the corresponding strength grade were grade four,four and second,respectively.The hardness values of end face,chord face and radial face were 105.38 Mpa,85.12 Mpa,and 87.15 Mpa,respectively,and the hardness of end face and chord face belong to very hard level,and was high-density wood.The comprehensive strength of wood was 186.53 Mpa,belonging to high-strength species.The comprehensive quality coefficient of wood was 277.83 MPa,belonging to high-quality wood.
