Two materials play major roles in modern aerospace: aluminum alloys for airframes and skin, and composites for structures. Here’s a look at both.
There are some aviation observers who predict composites and titanium will rule the roost when it comes to aerospace airframes and structures. But that seems rather unlikely. Aluminum is still lightweight, technically advanced in terms of forming and alloying, and it relatively low cost, especially when compared to titanium and composites....More
