据美国《航空周刊与空间技术》报道,在美国下一代的先进战术战斗机(ATF)的用材中,铝材的用量将下降到11%～20%,而复合材料将占主导地位,尤其是热固性树脂复合材料将占很大的比例.例如在YF-22原型机中,各种材料的重量比为(%):热固性复合材料20,热塑性复合材料15,钛合金33(其中62222合金22、6-4合金11),铝合金11,钢5,其他材料16;YF-23原型机的用材比例为(%):热固性复合材料50,钛合金20,铝合
According to the US magazine Aviation Week and Space Technology, the amount of aluminum used in the next generation of advanced ATF in the United States will fall to 11% to 20%, while composite materials will dominate, especially thermosetting For example, in the YF-22 prototype, the weight ratio of the various materials is (%): thermosetting composite 20, thermoplastic composite 15, titanium alloy 33 (62222 alloy 22,6 -4 alloy 11), aluminum alloy 11, steel 5, other materials 16; YF-23 prototype material ratio (%): thermosetting composite material 50, titanium alloy 20, aluminum
