Abstract
Abstract A nonwoven textile panel for use as a fire retardant and sound deadening barrier in the interiors of aircraft, comprised of three layers of nonwoven textile fibers of polyphenylene sulfide fibers and Nomex brand aramid fibers that have been carded, cross-lapped, needle punched and thermally bonded by heating the panel to the temperature softening point of the polyphenylene sulfide fibers. The fibers are capable of being thermoformed and retaining a permanent shape due to the thermoplastic properties of the polyphenylene sulfide fibers.
