Engineering transverse cell deformation of bamboo by controlling localized moisture content.

ABSTRACT: Bamboo's native structure, defined by the vertical growth pattern of its vascular bundles and parenchyma cell tissue, limits its application in advanced engineering materials. Here we show an innovative method that controls localized moisture content to shape natural bamboo into a versatile three-dimensional (3D) structural product. Different temperatures along the transverse direction of bamboo were used to induce directional water transport within the bamboo, so that the distribution of internal stress was shifted from the bamboo surface to the inner layers. The internal stress shifting enabled the control of the transverse deformation. After densification, a 3D-molded bamboo product was obtained that retained the natural heterogeneous structure. The molded bamboo had a high specific str
