Enhanced mechanical properties of CNTs/Mg biomimetic laminated composites

The conflict between strength and toughness of Mg matrix composites extremely limits its engineering application. Inspired by nacre, CNTs/Mg bionic laminated were prepared electrophoretic deposition. Compared with Mg, the yield elongation composite was increased 52% 59% respectively. structure intercepts dislocations layers. homogeneous composites, stacked produce higher back stress strengthening. In meantime, isolation effect CNTs layer makes plastic deformation more uniform which delays happening necking. During failure stage, has tolerance to cracks propagation cracks. Overall, is improved improving deformability delaying crack propagation.
