These mechanisms are inspired by nature, specifically by nacre. When nacre is loaded in tension, the aragonite tablets, making around 95 % of nacre, slide relatively to each other. The wedge shape of these tablets in combination with internal constraints, provided by the remaining 5 % of the organic interfaces, induces interlocking by frictional forces. This work investigates how this mechanism can be transferred to composite materials in order to increase their ductility in tension. Modelling is used to predict the tensile behaviour of interlocking configurations that exploit friction with either internal or external constraint. Two different design approaches of internally constrained specimens with various geometries are investigated using 3D printed materials. Externally constrained specimens, with different wedge angles are then investigated and finally this approach used with carbon composite structures.
