Fabric reinforcement for reinforcing alkaline cementitious matrix including warp yarns and weft yarns. To increase cohesive tensile strength of intersection points of the fabric the fabric has sufficient resinous coating over a substantial portion of the warp and weft yarns, before the fabric reinforcement is embedded within, or adhesively or mechanically bonded to the cementitious matrix, wherein the coating includes organic or inorganic adhesives/polymers, or the fabric has uncoated fabric modified by adhering fabric strands together where machine direction and cross-machine strands intersect, for example with cyanoacrylate or epoxy. Bond strength of the intersecting yarns of the fabric and the corresponding mechanical bond strength of the fabric to the cementitious matrix may also be enhanced by increasing roughness and/or surface area of the yarns and resulting fabric. Methods for making fabric, cementitious boards employing the fabric, and methods for making the cementitious board are also provided.

A sleeve for protecting an elongate member, including a bus-bar of a battery pack, and method of construction thereof are provided. The sleeve includes a knit wall having a circumferentially continuous outer surface extending along a longitudinal axis between opposite open ends. The knit wall is formed at least in part by multifilament flame-resistant yarn. The multifilament flame-resistant yarn is knit to form both the knit wall, and also first ribs extending lengthwise along the circumferentially continuous outer surface or second ribs extending annularly about said circumferentially continuous outer surface. An impervious, flame-resistant coating is bonded to an outer surface of the circumferentially continuous knit wall.
