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.

A fire retardant panel comprising: a non-woven fibrous core member comprised of a first staple fiber selected from the group consisting of a polyamide, a poly(imideamide), an aramid, a glass, a sulfar, a polyether-ether ketone, a carbon fiber, and a polybenzimidazole and a second staple fiber select

A fire retardant panel comprising: a non-woven fibrous core member comprised of a first staple fiber selected from the group consisting of a polyamide, a poly(imideamide), an aramid, a glass, a sulfar, a polyether-ether ketone, a carbon fiber, and a polybenzimidazole and a second staple fiber selected from the group consisting of a polyamide, a poly(imideamide), an aramid, a glass, a sulfar, a polyether-ether ketone, a carbon fiber, and a polybenzimidazole, said first and said second fibers being selected to have differing temperature softening points, inherent fire retardancy, and low smoke generation and offgassing at elevated temperatures, said core member having a first face and a second face; a first non-woven, fibrous outer member being secured to said first face; and a second non-woven, fibrous outer member being secured to said second face.
