Abstract:
An embodiment relates to an article and a method for producing an article including a plurality of substrates, and an adhesive bonded between at least two of the plurality of substrates. The adhesive can include a polycarbonate copolymer that includes reacted resorcinol, siloxane, and bisphenol-A. Another embodiment relates to an article having a first polyimide substrate, a second polyimide substrate, and an adhesive bonded between the first substrate and the second substrate. The article can have a 2 minute integrated heat release rate of less than or equal to 65 kilowatt-minutes per square meter (kW-min/m 2 ) and a peak heat release rate of less than 65 kilowatts per square meter (kW/m 2 ) as measured using the method of FAR F25.4, in accordance with Federal Aviation Regulation FAR 25.853(d).
Abstract:
A composition for the manufacture of a porous, compressible article, the composition comprising a combination of: a plurality of reinforcing fibers; a plurality of polyimide fibers; and a plurality of polymeric binder fibers; wherein the polymeric binder fibers have a melting point lower than the polyimide fibers; methods for forming the porous, compressible article; and articles containing the porous, compressible article. An article comprising a thermoformed dual matrix composite is also disclosed, wherein the composite exhibits a time to peak release, as measured by FAR 25.853 (OSU test), a 2 minute total heat release, as measured by FAR 25.853 (OSU test), and an NBS optical smoke density of less than 200 at 4 minutes, determined in accordance with ASTM E-662 (FAR/JAR 25.853).

Abstract:
A shaped composite article is prepared by a process wherein an aesthetic laminate having a clear outer arylate layer and a colored compatible resin layer is thermoformed into a desired shape, and then compression molded together with a reinforced resin material containing compatible resin to form a color composite of the desired shape having an outer layer of clear arylate polyester polymer with the compatible resin layer forming an adherent bond with the compatible resin in the resin reinforced material.
