Modern aircraft should ensure reduced fuel consumption as well as reduced CO2, NOx, and noise emission. To this end, airframe and engine manufacturing improvements are necessary. This implies the use of lightweight materials for airframes and engines and advanced turbine materials for discs and blades. The most widely used advanced high strength alloys for airframes are aluminium and refractory alloys and lightweight composite materials like Fiber Reinforced Plastic (FRP), Carbon or Glass Fiber Reinforced Polymer (C/GFRP), and Titanium Metal Matrix Composites (TiMMCs), and for aircraft engines, nickel and titanium alloys. These materials also have great potential for the automotive and biomedical sectors.

现代飞机应确保减少燃料消耗，减少二氧化碳、氮氧化物和噪音排放。为此，改进机身和发动机制造是必要的。这意味着机身和发动机使用轻质材料，而叶轮和叶片使用先进的涡轮材料。用于飞机机身的最广泛使用的先进高强度合金是铝和耐火合金以及轻质复合材料，如纤维增强塑料（FRP）、碳或玻璃纤维增强聚合物（C/GFRP）和钛金属基复合材料（timmc），以及用于飞机发动机的镍和钛合金。这些材料在汽车和生物医学领域也有很大的潜力。
