Those papers reveal damage mechanisms in bast fibers. Authors have developed an experimental setup based on 3D imaging at submicronic scale based on X-ray micro-tomography, combined with in-situ tensile experiments of both elementary fibers and bundles. The results reveal that the relevant scale that drives failure of hemp lignocellulosic fibers is submicronic. In-situ tensile experiments assisted by X-ray micro-tomography shows complex damage mechanisms involving the constitutive sub-layer structure, fiber extraction defects like kink bands, and the tubular porosity of the natural fiber.
