Next to advances in engine technology, new materials to make the rest of the aircraft are critical to improving performance and durability of aircraft and Dutch scientists say theyve hit on a winner. The researchers at the Delft University of Technology said in a recent news release that their CentrAl reinforced aluminum, which is a sandwich of aluminum and composite materials, is not only stronger than carbon-fiber composites, its 20 percent lighter and virtually impervious to fatigue. The news release says use of the material could save $100 billion in maintenance and fuel costs in the world-wide aviation industry. The material was developed by the university with help from the Dutch company GTM Advanced Structures and aluminum giant Alcoa. It was unveiled at a conference on the damage tolerance of aircraft structures in Delft last week. The researchers say its main use will be in aircraft wings where weight, strength and fatigue issues are paramount.
New Material Lighter, Stronger Than Carbon Fiber
Key Takeaways:
- Dutch scientists at Delft University of Technology, in collaboration with GTM Advanced Structures and Alcoa, have developed "CentrAl reinforced aluminum," a new material for aircraft.
- CentrAl is a composite sandwich that is stronger than carbon-fiber composites, 20% lighter, and virtually impervious to fatigue.
- This material is expected to save the global aviation industry $100 billion in maintenance and fuel costs, with its primary application being aircraft wings.
