  • Publication number: 20230312114
    Abstract: An aircraft evacuation slide assembly may be comprised of a plurality of composite textiles. Each composite textile may comprise a fabric substrate, an inner polyurethane coating, and an outer heat reflective coating. The outer heat reflective coating may comprise nanofillers that improve polymer properties, such as mechanical, barrier, thermal, flame retardancy, and electrical properties. Moreover, the outer heat reflective coating may comprise nanofillers that enable hot air welding and radio frequency welding of the plurality composite textiles to form the aircraft evacuation slide assembly.

  • Publication number: 20220153422
    Abstract: A self-healing fabric for an inflatable of an evacuation system may comprise a fabric layer, an interior thermoplastic polymeric layer formed over a first side of the fabric layer, and an exterior thermoplastic polymeric layer formed over a second side of the fabric layer. The interior thermoplastic polymeric layer may include a first healing agent. The exterior thermoplastic polymeric layer may include a second healing agent.

  • Publication number: 20210403728
    Abstract: A biocidal composite wall or surface fabric installable within an aircraft cabin or other vehicle interior space includes a flexible woven layer. The woven layer is treated on its outer surface with a biocidal polymer coating. For example, the polymer coating may incorporate biocidal microcapsules or nanocapsules configured for controlled release of biocidal compounds in response to physical contact or other stimuli. The released biocidal compounds compromise or kill microbial compounds deposited on the outer surface, e.g., via physical contact by passengers or crewmembers. The woven layer includes additional biocidal molecules incorporated into its fibers and strands, the biocidal molecules capable of biocidal action in response to contact with the fabric.

  • Patent number: 10399302
    Abstract: A packaged inflatable life raft includes a non-inflated life raft and an enclosure around the non-inflated life raft. The enclosure includes a film with a first layer that is innermost toward the non-inflated life raft, a second layer outer from the first layer, a third layer outer from the second layer, and a fourth layer that is outermost from the non-inflated life raft. Additionally, the first layer includes a heat-sealable polymer selected from polyethylene, polypropylene, or a halogenated polymer. At least one of the second and third layers includes a metal foil or a polymer vapor barrier. At least one of the second, third, and fourth layers includes a polyester or polyamide. At least one of the first, second, third, and fourth layers includes a halogenated polymer, or a polymer composition comprising a halogenated or non-halogenated polymer and a fire retardant.
