不同方向压缩木梭坯物理力学性能的研究

Study on Physico-mechanical Properties of Different Direction Compressed Wood Shuttle Blocks

以我国压缩木梭的主要原料东北色木为试材 ,对其径向、弦向、非标准向压缩木梭坯的密度、含水率、顺纹抗压强度、抗弯强度、冲击韧性进行测试。结果表明 :三个方向压缩后的压缩木测试的力学性能指标互有高低 ,但均满足压缩木梭的力学性能要求。

Taking Northeast China's mono maple, the main material of compressed wood shuttle as tested material, the density, water content, compressive strength paralled to the grain, bending strength and shock strength of radial, tangential and non standard direction compressed wood shuttle blocks have been studied. The results showed that the tested mechnical indexes were different among the three directions compressed wood but they could meet mechnical requirments of compressed wood shuttle blocks.
