ABSTRACT:
A composite sandwich element has at least one wall comprising phenolic resin binder and a layer of cellular polymeric foam or felt of imide polymeric material bonded thereto. In the presence of fire, the composite sandwich element has levels of heat release, flammability, smoke release and toxic gas release below predetermined levels considered suitable for use within the passenger compartment of a commercial aircraft. In preferred embodiments, there are two walls with the cellular polymeric material disposed therebetween. Preferably, the wall includes glass fibers in web form, with the polymeric resin binder serving as an adhesive or reinforcing binder. A barrier film, e.g. metallic or polymeric, may be included to render the composite sandwich element impermeable to air.
