Abstract
A flexible device with fire-barrier properties has a plurality of fibrous sheets and dry particles comprising molecules that are chemically and physically stable at room temperature and that generate an endothermic reaction upon raising the temperature. The sheets are joined together and the dry particles are inserted between the fibers of each sheet by needle-punching.
Claims21
A flexible device having fire-barrier properties, comprising:
- a plurality of sheets, wherein each sheet comprises inorganic fibers;
- and
- dry particles comprising molecules that are chemically and physically stable at room temperature and that generate an endothermic reaction upon raising the temperature,
- wherein said sheets are joined together by needle-punching and said dry particles are inserted between said fibers in adjacent ones of the plurality of sheets by needle-punching, the dry particles being substantially homogeneously dispersed within each of the sheets by the needle-punching.
