摘要 为了拓展竹展平板后续加工应用,对毛竹筒高温软化前后及展平板的显微构造及基本力学性能进行了观测与测试。结果表明:竹材软化后的薄壁细胞变形较小,展平后的薄壁细胞变形较大。对比原竹材与展平板的物理力学性能,展平板的密度和抗弯弹性模量分别比原竹材增大4.40%和6.76%,静曲强度、顺纹抗压强度和顺纹抗拉强度分别降低4.35%、4.32%和20.52%。除顺纹抗拉强度指标外,其他物理力学性能指标在展平前后变化不大,基本不影响其后续的加工利用。

Abstract:In order to expand the subsequent processing and application of bamboo flattened board, Phyllostachys edulis was used in this study for the observation of microstructure and the testing basic mechanic properties.The results indicated that the parenchyma cell of bamboo showed less deformation after the softening treatment,while it had obvious deformation after flattening treatment.Compared with the unprocessed bamboo in physic and mechanic properties,the flattened boards had higher density and modulus of elasticity of 4.40% and 6.76% respectively,while the bend strength,longitudinal compressive strength and longitudinal tensile strength were reduced 4.35%,4.32% and 20.52% respectively.The physical and mechanical properties had little change except longitudinal tensile strength before and after flattening,which had little impact on their follow-up processing and utilization.
