Secondary Structures

Solutions for particular challenges

Secondary Structures encompass a wide range of components across the wings, fuselage and tail of an aircraft. Fairings, access panels and non-pressurized doors require a unique combination of properties and processing. Many of these are sandwich structures which present particular challenges for design and manufacture. The applications require high mechanical performance and lightweight with cost effective manufacturing.
