Lightweight Materials
Lightweight materials refer to materials that have low density and high strength-to-weight ratio, making them ideal for use in space and astronautical engineering applications. These materials are used to reduce the weight of spacecraft and launch vehicles, which in turn reduces the amount of fuel required for launch and operation. Examples of lightweight materials used in space and astronautical engineering include carbon fiber composites, aluminum-lithium alloys, and titanium alloys.
