New materials are constantly being developed for aircraft structures from "summary" of Aircraft Structures & Systems EASA Module 13 B2 by
Advancements in materials science have led to a continuous stream of new materials that are being developed specifically for aircraft structures. These materials are engineered to possess characteristics that are crucial for the safe and efficient operation of aircraft. For example, they may have high strength-to-weight ratios, excellent fatigue resistance, or superior thermal properties. One of the main drivers behind the development of new materials for aircraft structures is the need to reduce the weight of aircraft. By using lighter materials, the overall weight of the aircraft can be decreased, which in turn leads to lower fuel consumption and operating costs. Additionally, lighter materials can also increase the payload capacity of the aircraft or improve its performance in terms of speed and range. Another important consideration in the development of new materials for aircraft structures is their ability to withstand the harsh operating conditions that aircraft are subjected to. For example, materials used in aircraft structures must be able to withstand extreme temperatures, high pressures, and rapid changes in temperature and pressure. They must also be resistant to corrosion, erosion, and fatigue, as well as being able to maintain their structural integrity over a long period of time. In addition to the performance characteristics of materials, their cost and availability are also important factors to consider. While some advanced materials may offer superior performance, they may also be more expensive to produce or harder to source. As a result, engineers must carefully balance the performance, cost, and availability of materials when selecting them for use in aircraft structures.- The development of new materials for aircraft structures is a dynamic and ongoing process that is driven by the need to improve the safety, efficiency, and performance of aircraft. By staying at the forefront of materials science and engineering, aircraft manufacturers can continue to push the boundaries of what is possible in terms of aircraft design and operation.
