Abstract:
In this paper we discuss the superior properties of strong/hard and simultaneously tough innovative bio-inspired hierarchical or fractal (2D-platelet-, 1D-fibre- or 0D-grained-reinforced) nanomaterials, ideal for (aero)space applications. As a practical example, we have treated recent experimental results on double cemented WC-Co, a two-level hierarchical grained material, demonstrating that hierarchy is able to increase the fracture toughness by a significant percentage.
