Abstract: A barrier article comprises a multilayer article that includes a plurality of core layers and a plurality of binder layers, wherein at least one core layer includes a woven or nonwoven fiber mat or fabric, and wherein at least one binder layer includes a silicone material. The plurality of core layers and binder layers are arranged in an alternating manner. The barrier article is operatively adapted to survive or withstand at least seven cycles of the Torch and Grit Test. The barrier article can be flexible and can provide a thermal insulation and blast protection barrier in, for example, a rechargeable electrical energy storage system.

Abstract: A three dimensional flame barrier is described herein. The three dimensional flame barrier comprises a flame resistant material, wherein the flame resistant barrier has a complex geometry that is defined by a height, width and length, wherein the height of the complex geometry is substantially greater than the thickness of the flame resistant material from which it is formed wherein the flame resistant material comprises inorganic fibers, inorganic particles and an inorganic binder. In some embodiments, the flame barrier article can further comprise a fire protection coating disposed on a first major surface of the flame barrier material.
