香脂木豆木材物理力学性质的研究

针对名贵实木地板用材香脂木豆（Myroxylon balsamum，俗称“红檀香”）开展物理性质和力学性能的研究。测定和分析结果表明：香脂木豆木材密度大，变形小，其全干密度为0．74g／cm^2，基本密度为0．68g／cm^2；差异干缩全干时平均为1．70，气干时平均为1．68；顺纹抗压强度为68．97Mpa，抗弯强度为149．78Mpa，综合强度为218．75Mpa，属于高。

This paper researched the physical and mechanical properties of Myroxylon balsamum, a very precious solid wood flooring material, The result of examination and analysis showing that Myroxylon balsamum has a high density and a low rate of shrinkage; its dried density is 0.74g/cm3; the basic density is 0.68g/cm3; the average dried contrast shrinkage is 1.70 and air-dried contrast shrinkage is 1.68; the compressive strength parallel to grain is 68.97Mpa; the bending strength is 149.78Mpa and the comprehensive intensity is 218.75Mpa which is considered high.
