Enhanced char integrity fabric

An enhanced char integrity fabric having a warp direction and a weft direction, wherein the fabric comprises:

• a plurality of warp yarns in the warp direction, wherein the warp yarns comprise thermoplastic fibers having a melting temperature less than about 300° C.;
• a plurality of weft yarns in the weft direction, wherein the weft yarns comprise thermoplastic fibers having a melting temperature less than about 300° C.;
• and,
• a plurality of char reinforcing yarns in the weft direction, wherein the char reinforcing yarns have a different composition than the warp yarns and a different composition than the weft yarns, wherein the char reinforcing yarns comprise non-melting fibers having a decomposition temperature greater than 300° C., wherein the char reinforcing yarns are in an amount of less than about 30% wt of the warp yarns, and wherein the tensile strength of the char reinforcing yarns is about equal or less than the tensile strength of the warp yarns.
