Tensile strength of bamboo from the innermost centre to the outermost skin increased from 72.8 to 187.3 MPa. This shows gradient tensile characteristics in bamboo. The experimental data match with the FEM analysis done using ABAQUS. Outermost section had the maximum tensile strength of 187.3 MPa. The reason for this large difference in tensile strength is that the innermost section has maximum amorphous material such as parenchyma as compared to outer surface. Density and hardness values determined also show gradient characteristics from innermost to outermost side. A continuous increase in hardness (Shore D, 48-70) is observed from centre to the outer surface. Density increases from 520 to 800 kg/m 3 from centre to the outer surface of bamboo. © KFRI 2006.
