 While typically being a time-consuming and somewhat uncommon process, an aircraft's aft pressure bulkhead can be wholly replaced.During the twenty-first century, various parties became increasingly interested in developing aft pressure bulkheads composed from composite materials, seeking benefits such as lower manufacturing costs, easier sealing, elimination of corrosion risk, along with weight and part count reductions.During the early 2000s, Airbus Group developed the largest manufactured resin film infusion structure then in production to function as the aft pressure bulkhead for their double-decker A380 airliner.
