    This study aims to quantify the density distribution, and specify the density distribution difference between internodes and nodes parts of Phyllostachys edulis (Moso Bamboo) in the radial, tangential and longitudinal directions. Due to the anatomical complexity of Moso bamboo, the measurement methods of bulk density are insufficient. In this work, Computed Tomography (CT) scanning has been selected to quantify the density distribution of Moso bamboo. Major findings from both anatomical analysis and CT scanning quantifications are that the Moso bamboo density of the internodes parts and the nodes parts reduce from the external surface to the internal surface of the culm wall in the radial direction. In the longitudinal direction, the internode parts of the Moso bamboo have relatively uniform density. Significant density fluctuation variations occur at the nodes parts of the Moso bamboo. The different proportions of the vascular bundles tissues and the parenchyma ground tissues dominate the density variation of the Moso bamboo in the radial direction. In the longitudinal direction, relatively uniform density of the internodes parts of the Moso bamboo is attributed to the straight vascular bundles. The significant density variation in the node parts is caused by the irregular intertwined vascular bundles

    Thermal diffusivity measurement of Phyllostachys edulis (Moso bamboo) by the flash method

    Get PDF
    Thermal diffusivity (ThD) of Phyllostachys edulis (Moso bamboo) has been determined in three directions of the cylindrical coordinate system of the culm. A flash tube and an infrared camera system was utilised for this purpose. The results, calculated by the MATLAB programme, serve as a database for numerical simulation studies concerning the heat and moisture transfer behaviour of Moso bamboo. The porosity and complexity of cellular structure and interconnectivity are the essential parametres influencing the ThD of Moso bamboo
