Abstract
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.
