Increased use of polymeric composite materials in aero-engines opens up opportunities for the development of new light engine components with, in turn, the potential to reduce fuel consumption and thus the climate impact of aircraft.

Such components will, during their lifetime, be subjected to combinations of mechanical and hygro-thermal load scenarios, unique for each engine type, engine architecture and flight mission. In such context, reliable methods for understanding and predicting the properties of the composites throughout their lifetime are critical. This project addresses the need through its aim to develop a method that predicts how mechanical properties of composites change over time and with thermo-mechanical loading. The project will develop a calculation methodology that describes the initiation and growth of damage in composites exposed to quasi-static or cyclic multiaxial loads during thermal and mechanical fatigue.
