What is the material of the 787 airframe?

The 787 Dreamliner offers a number of operational benefits due to the airframe comprising approximately half (by weight) carbon fiber reinforced plastic and other composites. As airlines add the 787 to their fleets, they are increasingly interested in repair methods for the airplane's composite structure.
