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.
