Fire Survivability Design of a Composite Hangar Door
A flat panel sandwich composite door was designed for a helicopter hangar on a surface ship. The door is a 4.6 m by 4.6 m, 127 mm thick door, with the top 4.1 m constructed of 127 mm thick balsa sandwich composite with 6.4 mm thick carbon-epoxy skins. Due to the threat of fire from helicopter crashes and fuel spills on the adjacent landing pad area, the door design included several fire survivability features that addressed the requirements of the U.S. Navy. To reduce flame spread over the door and smoke production, a phenolic cladding was bonded and mechanically fastened over the sandwich composite portion of the door. During a fire event on the landing pad area, the door was also required to prevent flame passage into the hangar until the fire on the landing pad could be controlled. To prevent flame passage around the perimeter of the door, intumescent seals were attached to the door in parallel with the neoprene seals. Large-scale testing was conducted to verify the flame spread and smoke production of the composite part of the door and the fire resistance of the door during a UL 1709 fire exposure.
