Minimization of the aviation sector’s environmental impact is the key goal of the new European Partnership for Clean Aviation, and a major step to fight climate change. To achieve it, an important role must be played by improvements in structural efficiency.
In this respect, high-performance composite materials, specifically fibre-reinforced polymers, have already brought major improvements. Still, as of today, consensus is that the potential of these materials is far from being achieved. Designing safe, reliable and efficient composite structures requires a thorough knowledge and understanding of the mechanisms involved in the failure of these materials.
Among these mechanisms, interlaminar fracture, or delamination, is one of the most critical. Standard procedures to characterise interlaminar fracture toughness exist, but their scope is restricted to use with unidirectional specimens. On the other hand, real components and structures are made using multidirecitonal laminates, where delamination may appear at any interface; under such conditions, interlaminar fracture toughness may be different from that obtained in standard tests. This results in uncertainties in structural design, and thus leads to oversized, inefficient structures.
The scope of the IFT-MultiLam project is therefore to enable interlaminar fracture testing of multidirectional composite laminates, thus leading to major improvement in the design of safe and efficient structures, for aviation and beyond.
