Abstract
Bamboo is a biomass material, which is a great substitute for wood with the potential to reduce the demand for woody materials. However, there is still a huge challenge to obtain crack-free bamboo boards with an ideal width due to the hollow cylinder and large curvature of bamboo culms. Herein, a method is demonstrated that can flatten bamboo culms by high-pressure saturated steam (180 °C/6 min) under a compression force of 8–10 MPa by two rollers. The macro- and micro-mechanical properties of the flattened bamboo board were also characterized in this paper. Results indicated that the saturated steam had no significant effect on the microstructure of the bamboo, whereas it decreased its hygroscopicity due to the degradation of the hemicellulose. The mechanical properties of the cell walls bamboo samples treated by softening and flattening were elevated compared with those of the untreated ones. During the flattening process, the parenchymal cells became compact. The elastic modulus of bamboo fibers increased from 16.14 to 18.75 GPa, while the hardness increased from 0.58 to 0.77 GPa. The improved mechanical properties of cell walls and increased density had a positive effect on the modulus of elasticity of the bamboo board.
