Abstract
A laminate sheet material comprising a first layer comprised of polymeric material and a second layer comprised of non-metallic fibers. The first and second layers at least collectively contribute to the laminate having at least one of a passing Flammability Value, Flame Propagation Value or Burnthrough Value. The laminate sheet material is useful, for example, in vehicles (e.g., aircraft), insulation blankets, insulation systems, and systems for limiting exposure of flammable insulation to an ignition source.
