Abstract
An enclosure comprises a thermal barrier (42) for protecting a heat sensitive component (40). The thermal barrier includes at least one endothermic layer (48, 54, 58) that includes water gelled with a thickening agent, absorbed onto a cellulose-comprising fabric or paper. The endothermic layer is sandwiched between layers comprising metal foil or sheet (49, 52, 56).

11. An enclosure comprising a casing forming a compartment surrounding a heat sensitive component, and a thermal barrier between the casing and the heat sensitive component,
wherein the thermal barrier includes at least one endothermic layer comprising water gelled with a thickening agent and absorbed onto a cellulose-comprising fabric or paper and sandwiched between layers comprising metal foil or sheet, and wherein the thermal barrier is configured to provide a support for the heat-sensitive component before and after endothermic decomposition of said at least one endothermic layer.
- 22. An enclosure comprising a thermal barrier for protecting a heat sensitive component, wherein the thermal barrier includes at least one endothermic layer comprising water gelled with a thickening agent, absorbed onto a cellulose-comprising fabric or paper and wherein said endothermic layer is sandwiched between layers comprising metal foil or sheet, and wherein said thermal barrier is configured such that a plurality of said endothermic layers surround said heat sensitive component substantially filling said enclosure.
- 30. A flight data recorder comprising a memory module in an enclosure, the memory module being surrounded by a thermal barrier that includes at least one endothermic layer comprising water gelled with a thickening agent and absorbed onto a cellulose-comprising fabric or paper and sandwiched between layers comprising metal foil or sheet, the thermal barrier providing a support for the memory module before and after endothermic decomposition of said at least one endothermic layer.
