(a) Stiffness (E) and (b) strength (σth) contour maps of each constituent layer of the proposed heterogeneous composite. The stiffness and strength as a function of aspect ratio and volume fraction of mineral platelets are predicted by the shear lag model24,55. The regions surrounded by the red ellipses in (a) and (b) indicate the stiffness and strength of the constituent layers of the proposed heterogeneous composites, respectively.
