巴山松木材物理力学性质的研究

A Study on Physicomechanical Properties of Pinus henryi Mast.

本研究提供了巴山松木材物理力学性质试验结果:气干密度0.539g/cm^3,体积干缩系数0.625％,顺纹抗压强度38.10N/mm^2,抗弯强度86.8N/mm^2,抗弯弹性模量130kN/mm^2,端面硬度27.1N/mm^2,冲击韧性0.0523Nm/mm^2。结果表明,其主要物理性能和力学性能介于油松和马尾松木材之间,巴山松木材是一种优良的建筑工程用材和家具制造用材。

The results of experiments on the physicomechanical properties of pine (Pinus henryi Mast.) wood were presented:density air-seasoned 0.533 g/cm3, caefficient of cubical shrinkage 0.625%, compressive stress parallel to grain 38.10 N/mm2, bending stress 86.8N/mm2, elastic modulus of staticbending strength 130kN/mm2, hardness of cross section 27.lN//mm2 and toughness value 0.0523 Mm/mm2.The results showed that its main physical and machanical properties are between those of Pinus tabulaeformis and P.massoniana. Pinus henryi wood is an excellent material in architecture and furniture manufacture.
