  • Patent number: 6358591
    Abstract: An insulation blanket is disclosed that contains fire-blocking materials for preventing rapid penetration of fire into an aircraft fuselage in case of a fire outside the aircraft. The insulation blanket contains at least one layer of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers of fire-blocking material. The fire blocking material is wider than the thermal-acoustic insulation so that it may be folded against and attached to adjacent structural frame members of the fuselage. In the alternative, a thermal-acoustic insulation material is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members of the aircraft using attachment posts or spring clips.

  • Patent number: 6228784
    Abstract: There is disclosed a heat resistant cloth for fire fighting. At least an inner surface of a fluororesin film is subjected to plasma discharge treatment to form a treated surface. A vacuum-deposition film made of a bright metal such as aluminum is formed on the treated surface of the fluororesin film without use of a primer. The vacuum-deposition film on the treated surface is bonded to an outer surface of a substrate fabric through use of a silicone rubber adhesive in order to form a heat-reflecting layer on the outer surface of the substrate fabric. Since no primer coating layer is used, the heat reflecting layer can prevent a decrease in brightness, which would otherwise occur due to cracks generated in the primer coating layer. Thus, a decrease in heat reflectivity at high temperature is prevented. Since no flammable synthetic resin layer is used at the surface of the heat reflecting layer, flame resistance can be improved.

    Abstract: An improved bituminized flame-retardant textile material is provided that effectively overcomes bitumin adhesion difficulties associated with products of the prior art wherein the flame-retardant present on the surface of a textile support interfers with and hinders the achievement of bitumin adhesion. An anti-flame agent is applied in a quantity of 20 to 100 grams per square meter over 30 to 90 percent of the upper surface of the textile support. The remaining portions of the upper-surface of the textile support are free of the anti-flame agent. It surprisingly has been found that the surface portions of the textile support that are free of the anti-flame agent provide areas for the achievement of optimum bitumin adhesion with the textile support while still making possible entirely satisfactory flame retardancy for the overall product.

  • Patent number: 5891553
    Abstract: A film having a width of at least about one foot as defined by the cross machine direction thereof and a substantially uniform average thickness of less than about 10 mils is formed of a crosslinkable thermoplastic olefin polymer, a crosslinking agent, and preferably a flame retardant. The film can be combined with a suitable substrate to form a prepreg or coated substrate, and the prepreg or coated substrate can be subsequently treated under conditions to crosslink the olefin polymer and to form a rigid composite structure. The composite structure is particularly useful for printed circuit board applications.

  • Patent number: 5863846
    Abstract: A slurry is molded from ceramic fibers and/or microparticles to form a soft felt mat which is impregnated with a sol prior to drying the mat. A catalyst for the sol is caused to diffuse into the mat by exposing the mat to the catalyst and subjecting the mat to a soak time during which the catalyst diffuses into the mat and causes the sol to gel. The sol-gel binder forms bonds so that the mat is dimensionally stabilized. The mat is dried to produce ceramic insulation.Ceramic insulation having a consistent microstructure and a fully gelled sol-gel binder through its entire thickness is also provided.

  • Patent number: 5756406
    Abstract: A method for making a soft trim composite, and a resulting improved soft trim composite, used for example as a motor vehicle interior trim component or a seat covering component, comprises laminating a surface covering onto an expanded cellular layer, where a cellular layer is provided, to form a bilaminate, and placing a heat barrier insert, comprising nonwoven fibers coated on one side with thermoplastic resin in a mold between the bilaminate and a substrate created in a molding step. The heat barrier insert dissipates heat from substrate molding, permitting a substantially uniform and complete bonded relation to be achieved between substrate and insert, as well as between insert and bilaminate, virtually simultaneously with creation of the substrate, and without causing substantial damage to the bilaminate. An improved soft trim composite made by the method described, is also provided.

  • Patent number: 5698477
    Abstract: The present invention provides an adhesive cloth tape for bundling the component wires of a wiring harness for use, for example, on an automobile. Conventional adhesive polyvinyl chloride tapes and adhesive acetate cloth tapes have problems that wiring harnesses bundled by these adhesive tapes generate fluttering and rustling noise while the automobile is running, and conventional adhesive cotton cloth tapes reduce the efficiency of bundling work because these tapes have high tear strength, though their noise preventing performance is excellent. The present invention provides an adhesive cloth tape solving the foregoing problems in the conventional adhesive cloth tapes, having a tensile strength of 8 kgf/19 mm or higher with respect to the direction of its length, and comprising: a woven base cloth of 0.
