and 29 layers of glass fiber. Glare is currently made by GKN-Fokker and Premium AEROTEC. GKN-Fokker manufactures 22 of the 27 A380 Glare fuselage shells at its in Papendrecht, Netherlands, which uses an autoclave with a length of and a diameter of . The company produces sheets of , which incorporates the milling of door and window cutouts on a 5-axis milling machine. Premium AEROTEC manufactures the remaining five shells in Nordenham, Germany in an autoclave with a usable length of and an internal diameter of . The company also produces the Glare2A butt straps for the A400 program. Its output was per month as of 2016. With Airbus ending production of the A380 in 2021, Glare will go out of volume production unless it is selected for another airplane manufacturing program. Future developments Since around 2014, Airbus, its two current Glare suppliers, and Stelia Aerospace have been collaborating to manufacture Glare in a high-volume, automated production setting that will deliver larger fuselage panels for aluminum aircraft. Using robots for tape laying and other tasks, automated production will involve a single-shot bonding process that will cure aluminum, pre-preg, stringer, and doublers simultaneously in the autoclave, followed by a single nondestructive testing (NDT) cycle, instead of the stringers and doublers requiring a second bonding and NDT cycle in the existing process. The belief is that the material will reduce fuselage weight by 15 to 25 percent compared to the aluminum sections they would replace on single-aisle aircraft such as the Boeing 737 and the Airbus A320. (Before the announcement of the A380 production stoppage, the automation program was also intended to lower the weight the A380 Glare sections by at a manufacturing cost of 75% of the existing A380 Glare panels.) To support these single-aisle aircraft production goals, GKN-Fokker planned to open an automated production line at its site in 2018, with a goal of manufacturing panels of up to in size and increasing the production rate by a factor of ten. In targeting a fifty-fold increase of Glare production capacity to per month, Premium AEROTEC planned to update its automated test cell in summer 2018 to manufacture demonstrator panels of . This size will match the largest Glare panels to be potentially used by Airbus in short-range and medium-range aircraft. The Glare automation process for prototypes reached technology readiness level (TRL) 4 in late 2016, exceeded TRL 5 as of
