Nonwoven flexible composites |
摘要 |
Embodiments of the present invention provide systems and methods for using nonwoven materials for evacuation slides, life rafts, life vests, and other life-saving inflatable devices. The nonwoven materials have a substrate layer with continuous filament fibers formed in various directions. The substrate layer then has a first and second layer of polyurethane. The first and second layers of polyurethane may be laminated or coated to a nonwoven substrate of the filament fibers. An isocyanate-based adhesive or primer may be particularly useful in causing cross-linking of the materials to one another. |

1. An inflatable evacuation slide, life raft, life vest, or other emergency flotation or inflatable device, comprising:
a flexible composite material, comprising
a substrate of nonwoven material comprising a plurality of straight laid fibers;an isocyanate-based adhesive or primer; anda first layer of polyurethane on one surface of the substrate of nonwoven material and a second layer of polyurethane on a second surface of the substrate of nonwoven material; wherein the flexible composite material is a high-strength lightweight material with a tensile strength of at least about 190 pounds per inch and a weight of about 8 ounces per square yard or less, wherein the flexible composite material is adhered to itself to form a tubular structure or is adhered to another flexible composite material. |
