Abstract: A non woven fire blocking seat fabric particularly suited for aircraft applications is disclosed. The fabric is a nonwoven, multiplied flame resistant fabric comprised of at least two felted plies, each ply being further comprised of fibers selected from the group consisting of aramid fibers, polybenzimidazole fibers, and phenolic fibers, wherein the combined percentage by weight of said aramid and phenolic fibers is approximately 80% by weight of said felted ply with the aramid fibers being present in the range of about 10% to 60% and the phenolic fibers being present in the range of about 20% to 70%.; and the plies are united into a single fabric by fibers which are needled from the respective ply into the other ply. In the preferred fabric a stabilized woven scrim is positioned between the plies of the fabric. In the preferred fabric the scrim is of glass material.
