N2 - To overcome the competitive nature of stiffness and toughness, multi-layered structures are a potential solution. By using intelligent design criteria, it is possible to severely increase toughness while keeping the stiffness of the structure at a sufficiently high level. This method can be used for smart pipe-wall design in demanding applications. First multi-layer composites of pure and also highly reinforced thermoplastic materials have been produced and tested with regard to their toughness-increase in bending set-up, with interfaces perpendicular to the applied force. As expected, interface properties and mechanical property mismatch play a key role in the development of optimized structures.
