Building aircraft wings with a special aluminium fibre combination makes them nearly immune to metal fatigue. The application of this technology, partly developed atDelft University of Technology，将导致大量节省。这种特殊材料的异常品质（称为中央，中央钢筋的缩写）可以为开发真正节能的“绿色”飞机做出重大贡献。降低燃油消耗和降低维护成本可能会导致全球节省高达750亿欧元。
疲劳是一种现象，它会在长期暴露于循环负荷后影响材料。欧洲杯足球竞彩由于负载的变化，骨折最终发生。新型高质量的中央铝制结构比最近在飞机机翼（如波音787）中使用的碳纤维增强塑料（CFRP）结构强，而使用中央机翼结构，可以将重量减少20次。与CFRP构建体相比。此外，使用中心结果大大降低制造和维护成本。
中心概念包括纤维金属层压板（FML）的中心层，夹在一个或多个厚的高品质铝层之间。这会产生强大的建筑材料，不仅非常强大，而且对疲劳不敏感。中央技术允许立即进行简单的维修，就像铝制构建体中一样，但使用CFRP构造时并非如此。
This patented new concept is one of the results of an intensive collaboration between the company GTM Advanced Structures, founded in The Hague in 2004 and specialising in new aircraft materials and constructions, the American aluminium company Alcoa, and the Faculty of Aerospace Engineering of Delft University of Technology. During a conference in Delft (Conference on Damage Tolerance of Aircraft Structures: 25-28 September 2007), GTM and Alcoa have presented the new concept to international experts in the field of metal fatigue and damage sensitivity of aircraft constructions. The US Air Force, Alcoa and GTM will also shed new light on the fact that the new CentrAl materials create possibilities for so-called ‘Carefree structures’. These are aircraft constructions that are less sensitive to damage caused, for example, by fatigue, hail storms, other weather phenomena, trucks that collide with the aircraft and corrosion. Carefree aircraft constructions will be characterised by significantly reduced maintenance costs.
