A new approach for fabricating crack-free, flattened bamboo board and the study of its macro-/micro-properties

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...
