It's extremely easy to form, very strong, and very light. Carbon fiber is the material they make super cars, racing motorcycles, and yes, aircraft from. However, it's very expensive and can be brittle if it's compromised. It can also be welded using nothing more than a superglue-like substance known as C.A. glue (cyanoacrylate or Superglue).
Aluminum is also light and strong. However, it's bendable and more flexible. It's less expensive, readily available, and can make an effective airframe. It is also used in cars, racing motorcycles, and aircraft. It cannot...
