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.
Claims52
A flexible laminate sheet material comprising:
- a first layer comprised of a film of high temperature stable polymeric material, wherein the high temperature stable polymeric material is stable at a temperature of about 150° C.;
- and
- adhesively bonded to the first layer by a flame-retardant adhesive material a second layer comprised of a fabric of non-metallic fibers;
- wherein the average thickness of the laminate sheet material range from about 75 to about 1200 micrometers;
- wherein the laminate sheet material retains its integrity when the laminate sheet material is wrapped once around a 6 millimeter diameter rod and then unwrapped;
- wherein at least the first and second layers collectively contribute to the laminate sheet material having at least one of a passing Flammability Value I, a passing Flammability Value II, a passing Flame Propagation Value I, a passing Flame Propagation Value II, or a passing Burnthrough Value.
A system for limiting exposure of flammable insulation material to an ignition source comprising:
- a flexible laminate sheet material comprising:
- a first layer comprised of a film of high temperature stable polymeric material, wherein the high temperature stable polymeric material is stable at a temperature of about 150° C.;
- and
- adhesively bonded to the first layer by a flame-retardant adhesive material a second layer comprised of a fabric of non-metallic fibers;
- wherein the average thickness of the laminate sheet material ranges from about 75 to about 1200 micrometer;
- wherein the laminate sheet material retains its integrity when the laminate sheet material is wrapped once around 6 millimeter diameter rod and then unwrapped;
- wherein at least the first and second layers collectively contribute to the laminate sheet material having at least one of a passing Flammability Value I, a passing Flammability Value II, a passing Flame Propagation Value I, a passing Flame Propagation Value II, or a passing, Burnthrough Value;
- wherein the laminate sheet material is positioned between the flammable insulation material and the ignition source such that the first layer of the laminate sheet material is adjacent to the flammable insulation material.
An insulation system comprising:
- flexible laminate sheet material comprising:
- a first layer comprised of a film of high temperature stable polymeric material, wherein the high temperature stable polymeric material is stable at a temperature of about 150° C.;
- and
- adhesively bonded to the first layer by a flame-retardant adhesive material a second layer comprised of a fabric of non-metallic fibers;
- wherein the average thickness of the laminate sheet material ranges from about 75 to about 1200 micrometers;
- wherein the laminate sheet material retains its integrity when the laminate sheet material is wrapped once around a 6 millimeter diameter rod and then unwrapped;
- wherein al least the first and second layers collectively contribute to the laminate sheet material having at least one of a passing Flammability Value I, a passing Flammability Value II, a poising Flame Propagation Value I, a passing Flame Propagation Value II or a passing Burnthrough Value;
- and
- insulation material;
- wherein the laminate sheet material and the insulation material are positioned such that the first layer of the laminate sheet material is adjacent to the insulation material.
An insulation blanket comprised of:
- a flexible laminate sheet material comprising:
- a first layer comprised of a film of high temperature stable polymeric material, wherein the high temperature stable polymeric material is stable at a temperature of about 150° C.;
- and
- adhesively bonded to the first layer by a flame-retardant adhesive material a second layer comprised of a fabric of non-metallic fibers;
- wherein the average thickness of the laminate sheet material ranges from about 75 to about 1200 micrometers;
- wherein the laminate sheet material retains its integrity when the laminate sheet material is wrapped once around a 6 millimeter diameter rod and then unwrapped;
- wherein at least the first and second layers collectively contribute to the laminate sheet material having at least one of a passing Flammability Value I, a passing Flammability Value II, a passing Flame Propagation Value I, a passing Flame Propagation Value II, or a passing Burnthrough Value;
- and
- insulation material;
- wherein the laminate sheet material and the insulation material are positioned such that the first layer of the laminate sheet material is positioned adjacent to the insulation material.
