Boeing’s $1 billion composite wing center (CWC) will start fabricating the first spar for the 777X wing this year, marking the start of a process of composite wing making on a scale never before tried in a commercial aircraft program. Inside the 1.3-million-square-foot building in Everett, Washington, a single autoclave over the past year has baked composite parts for preproduction test articles such as stringers, panels and wing skins, in preparation for low-rate production and assembly at Boeing’s adjacent horizontal build line.
