Composite wall lining, esp. for aircraft - comprises fire resistant, low smoke-and gas-generating cork core with higher modulus faces

摘要

A composite component for use as an interior wall lining, esp. for aircraft comprises a cork core with faces of a higher modulus material. The cork is saturated in a binder which is fire resistant, prevents heat build up and does not produce toxic gas in a fire, therefore acting as a self-extinguishing agent. The panel comprises a core (1) of cork saturated in a fire resistant binder with low smoke and toxic gas generation. Higher modulus faces (4, 5) are bonded (2, 3) to each side of the core (1) with adhesive e.g. phenol or polyurethane based. The faces (4, 5) may be fibre reinforced plastic e.g. glass reinforced phenol formaldehyde or metal plate e.g. steel, aluminium. USE/ADVANTAGE - The composite panel can be used as a wall lining or partition within passenger aircraft and is fire resistant without increasing cost.
