The aerospace industry has been continuously evolving, especially since the last decade, as efficiency and sustainability have taken centre stage. Industry stakeholders have been working on innovations that can support this need.

Multiple technological elements need to be developed to support the development and deployment of next generation aircraft. Technology elements such as battery technology, propulsion systems, avionics, communications systems, and, most importantly, materials that can support the requirements of advanced and innovative aircraft/engine platforms.

Prerequisites of materials used in aviation:

The aviation industry is one of the most regulated industries, and for the right reasons, given the speeds and altitude at which aircraft operate while carrying hundreds of passengers onboard. Materials that can be used on an aircraft need to fulfil certain basic criteria to be certified for use.

Key specification requirements for materials • Resistance to Extreme Temperatures, Pressure, and

Vibration: Equipment needs to be able to handle wide variations in temperature and pressure during flight.

• Machineability: The materials should be able to be machined to odd and varied shapes and sizes without losing their characteristics.

• Repairability and Lifespan: The materials should be able to be repaired to their original form without losing their inherent qualities and specifications.

• Resistance to Extreme Stress and Fatigue: Materials need to be able to withstand high degrees of stress and fatigue to maintain the safety of the payload.
