Healing at the interface: Molecular mechanisms in self-repairing polymer composites

Project summary

Modern high-performance polymer composites are widely used, from aircraft to wind turbines. Despite their advantages, these materials are prone to damage: even small cracks can lead to failure of entire structural components and generate significant waste. Self-healing polymer composites could offer a solution, though their development is still at an early stage. This project aims to uncover the self-repair mechanisms of carbon-fibre-reinforced composites. In the first phase, molecular simulations will be used to investigate how damage initiates at the interfaces between components – such as the epoxy matrix and carbon fibres – and how these processes can be reversed. In the second phase, the effects of different chemical modifications on self-healing efficiency will be studied. The ultimate goal is to develop smarter, more sustainable composites that last longer, reduce waste, and help industries move toward a more circular, eco-friendly future.
