a specified amount of constituent elements followed by hot rolling, cold rolling to a predetermined thickness and softening under predetermined conditions. CONSTITUTION:An alloy consisting of 5.1-8.2% Zn, 1.8-3.4% Mg, 1.2-2.6% Cu, <=0.20% Ti, and the balance Al and impurities or further ...
In addition to processes that result in materials with specific high-performance properties, chemical engineers continue to design new processes for the low-cost manufacture of polymers. 除了这些可以得到具有特别高性能的材料的加工过程,化学工程师们还设计一些新的工艺过程以生产低成本的聚合物。 2.Polymer ...
In a process to manufacture an aircraft fuselage stringer in composite material, a form core has a hollow profile with longitudinally segmented folding sides. The form core is converted as required from open to closed (A) presentation for carbon fiber layup. On completion of the fiber and ...
the original material (in some cases up to 90%), which should be recycled as part of the sustainable engineering approach to aircraft production. The manufacture of compositecomponents also results in trimmed and dust materials, which can also be recycled using the same processing methods as used...
