New alloy super durable, corrosion resistant

The two companies of the same university in the US and the Netherlands have jointly successfully researched a new alloy that is super durable and resistant to corrosion. Using this alloy to produce aircraft wings would save $ 100 billion annually.

Named CentrAl (Central Reinforced Aluminum), this new material is the result of cooperation between 3 units: GTM Advanced Structures (Netherlands) specializing in machine materials Flight, Alcoa Aluminum Company (USA), and Aviation Engineering Department of Delft University of Technology (Netherlands).

CentrAl has a structure that consists of fibrous metal laminate (FML) layers, enclosed by one or more high quality, thick aluminum layers. With this composition, CentrAl is a construction material that is not only solid but also resistant to metal corrosion.

Metal corrosion is a condition that reduces the quality of metal after a long time of use. Under the impact of the load, cracks will gradually appear and weaken the structure of the metal.

The aircraft produced by CentrAl will have much greater durability than the wing made of carbon fiber reinforced plastic (CFRP) - the material being used to manufacture wings of many types of aircraft, in there is Boeing 787.

Not only super durable, CentrAl also helps aircraft wings about 20% lighter than wings made from CFRP. At the same time, CentrAl also facilitates aircraft wing repairs made much simpler and faster than wings with CFRP.

Moreover, this new, high-quality material also helps the aircraft wing consume less energy and does not require expensive maintenance.

With the advantage of reducing production costs and saving maintenance costs, this new material, when widely used, will save a cost of up to US $ 100 billion worldwide.

According to the team, with all these characteristics, CentrAl will contribute significantly to the production of truly "green" and energy-efficient aircraft.

At the recent 4-day (September 25-28) conference in Delft (Netherlands) on 'Aircraft structural damage tolerance', two companies GTM and Alcoa presented this new material. before international experts.

Alcoa, GTM and the United States Air Force also stressed that CentrAl is capable of creating so-called "non-worrying structures" - that is, structures that are less sensitive to damaging factors, such as needle corrosion. type, hail, collision between aircraft and truck, as well as other adverse conditions during use.
