Research data supporting "Thermal conductivity of engineered bamboo composites"

Abstract

Thermal conductivity measurements of various engineered bamboo products, including laminated bamboo, bamboo oriented strand board, laminated bamboo esterilla sheet and bamboo veneer board, using the transient plane source (TPS) technique on a Hot DiskTM Thermal Constants Analyser. The materials were obtained as 10-20 mm thick panels, 200-400 mm square. The fibre orientation and layer configuration (including relative thickness of the layers) of the different products is presented in Table 1, and qualitatively visible in Fig. 2 of the published paper. For the products used here, laminated bamboo and bamboo veneer board are comprised of Moso bamboo (Phyllostachys pubescens), while bamboo oriented strand board and laminated bamboo esterilla sheet of Guadua (Guadua angustifolia). Some of the products were also obtained with environmental-protective treatments and external, micro-thickness coatings, as is necessary when using the products for exterior use. The volumetric composition, in terms of solid cell wall material, air and polymer matrix, is also estimated for the various products. Finally, considering bamboo and wood composites as three-phase composites, the trend between thermal conducitvity and density is modelled using various composite structure-property relations, including the Rule of Mixtures, Halpin-Tsai equations, C-S and E-S models. A template for the modelling is also presented.
