Aerospace materials |
Aerospace materials are often specific metals that have either been discovered, or are coming into prominence for their use in aerospace purposes. Numerous past aerospace materials are still used today as they possess space saving properties. The materials include Titanium, rubber, and composites. Some of the materials that were developed and used in the past and not in present time are ceramic tiles, glass, and synthetic leather.
Aerospace materials come in extensive variety and all have created their unique profile. Some of the most common metals used for aerospace are rubber, titanium, and composite alloys. The properties of Titanium have been changed so that it can stand extreme conditions, including the high G-forces of space. As titanium is lighter in weight compared to most of the other metals, it is used in numerous aerospace vehicles, making the control, and maneuver of Earth orbit easier. Other materials such as rubber composites, strong metal alloys, and other composites have their own unique properties, where some are tougher or weaker than others. These features can be advantageous for the manufacturing and design procedure, when the paramount of the operation of the system are strength and stiffness properties of the material.
Combining hardness and lightness of the material makes it stronger and less susceptible to deformation, which takes on a more round shape that its counterparts. The development of new materials has driven the discovery of several new materials that use lightweight materials. For instance, aluminum. It was always referred as an inferior alloy as it is light weight, corrosion resistant, and durability. Aluminum is extremely ductile, and the resistance to impurities like oxygen helps to make it the perfect metal for airframe structure. Other metals that are used in the construction of airframes are steel or nickel alloys. The new aerospace materials are preferred over conventional counterparts also due to their increased stiffness and dimensional stability. Recently, in March 2021, GKN Aerospace, leading a new UK industry group called ASCEND (Aerospace and Automotive Supply Chain Enabled Development) announced the development of composite materials and process technologies for the next generation of energy efficient aircraft.
