Abstract
An enhanced char integrity fabric containing a plurality of warp yarns in the warp direction and a plurality of weft yarns in the weft direction. The warp yarns and the weft yarns contain thermoplastic fibers having a melting temperature less than about 300° C. The enhanced char integrity fabric also contains a plurality of char reinforcing yarns in at least the warp direction. The char reinforcing yarns have a different composition than the warp yarns and the weft yarns and contain non-melting fibers having a decomposition temperature greater than 300° C. The char reinforcing yarns are in an amount of less than about 30% wt of the warp yarns and the tensile strength of the char reinforcing yarns is about equal or less than the tensile strength of the warp yarns.
