Definitions

  • the invention relates to fire resistant materials. More specifically, the invention relates to flexible laminate material for acting as a fire barrier to hold back flames of a fire from critical areas for a period of time.
  • Patent No. 2,801,427 discloses a fire barrier product including a glass fiber fabric laminated to an impermeable film or foil.
  • Patent No. 3,913,309 describes a blend of fibers in a yarn or a fabric, wherein some of the fibers of the com ⁇ posite have lower melting points than others so that on exposure to heat, melting of some fibers occurs, accom ⁇ panied by the formation of deposits which are said to increase heat resistant properties.
  • Patent No. 4,001,477 also discloses blends of fibers in a flame resistant cloth. Synthetic fibers may be blended with one another or with fire resistant fibers including glass fibers.
  • Patent No. 4,348,450 is directed to a packaging mater ⁇ ial having fire retardant properties.
  • the material is laminated of several layers including a metal foil sheet bonded to a non-woven glass fiber paper-like sheet.
  • Patent No. 4,690,851 is directed to a textured glass fiber and carbon fiber product in which the fabric is impregnated with a phenolic resin, in order to produce a SUBS TITUTE SHEET fabric having fire resistance, good mechanical strength and light weight.
  • the fabric was intended for use in articles in an aircraft interior.
  • Patent No. 4,690,859 relates to a fire barrier fabric for upholstered furniture and bedding, including a glass fiber abric coated with an encapsulating coating intended to minimize self abrasion by the glass fibers.
  • the coat ⁇ ing adheres to the glass fabric even when subjected to heat and flames.
  • the coating is said to avoid contributing to the fuel value of the fabric and to be "breathable", i.e. having at least some degree of porosity.
  • the encapsulating coating was applied to the glass fiber fabric in the form of a foam.
  • a primer coating may first be applied to the glass fiber fabric to improve adhesion of the encapsulating coating.
  • None of the fire barrier products or constructions previous to this invention embraces a cloth or fabric which is very thin, flexible, very light in weight, wear resist- ant, tough and resistant to tearing, and substantially impervious to moisture. It is an object of the present invention to provide a lightweight fire barrier fabric having all these advantageous properties, the product being particularly useful in aircraft applications. Disclosure of the Invention
  • a fire barrier fabric product achieves the advantages of lightness in weight, a barrier to moisture, protection against destructive wear of the fire barrier fibers, high strength with resistance to tearing, and an efficient barrier against burn through of flame for an appreciable and useful length of time.
  • the plastic film provides a moisture barrier with low moisture vapor transmission and preferably is adhered to the glass fiber fire barrier mesh by an adhesive.
  • the plastic film in conjunction with the adhesive tends to hold the brittle fibers in place, tending to prevent self-abrasion, and it also provides a protective, low-friction surface which protects the brittle fibers against abrasion from other adjacent materials and stabilizes the fabric for handling and processing.
  • Figure 1 is a perspective, exploded view illustrating the construction of a preferred fire barrier material in accordance with the invention.
  • Figure 2 is a plan view showing one side of a section of the material, greatly enlarged as compared with Figure 1.
  • Figure 3 is a cross-sectional view of the material, generally as seen along the lines 3-3 in Figure 2.
  • Figure 1 shows in exploded view one preferred construction of a fire barrier material 10 of the invention.
  • the fire barrier material 10 illustrated in Figure 1 has the qualities of being thin, flexible, not creasing when wrinkled, maintains shape, light in weight, wear resistant, tear resistant and substantially impervious to
  • the fire barrier material 10 includes a woven glass fiber mesh fabric 12, a scrim webbing 14, a heat seal adhesive coating 16 and a thin film 18 which is substantially impervious to moisture.
  • Figure 1 is an enlarged view with the components shown considerably larger than actual size; for example, the spacing in the scrim webbing 14 may be about 1/16 to 1/2 of an inch. Also, the scale and relationship of sizes and thicknesses of the various components is not intended to be accurate.
  • the glass fiber mesh fabric 12 may be a style 108 or 1080 glass fiber fabric (as designated by manufacturer Burlington Industries, for example) finished with a silane coupling agent or chromate coupling agent to give a permanent bond to the glass fiber.
  • 1080 glass fabric comprises 60 X 47 yarns per inch of 900 1/2 E-glass yarns, a relatively light but very tight weave. Such fabric is common in the printed circuit field as a con ⁇ struction material for PC board stock.
  • the glass fabric 12 provides substantially all the fire barrier qualities of the fire barrier material 10.
  • the 1080 glass fabric has a thickness of about .002 inch and a weight of approximately 1.44 ounce per square yard.
  • the scrim webbing 14 imparts tear resistance to the fire barrier material 10, in both the warp direction (warp fibers 14a, Figures 1 and 3) and the fill direction (fill fibers 14b).
  • the warp and fill fibers of the scrim webbing 14 may both be, synthetic or glass fibers for example, 70d nylon.
  • the fill yarn fibers 14b preferably are adhesive soaked, with the warp yarn fibers having adhesive applied at crossover points.
  • the adhesive layer 16 may be a heat-seal coating
  • the heat-seal adhesive coating may comprise, for example, polyurethane adhesive with fire retardants added.
  • the thin film 18, the bottom layer of the composite laminate material 10 as seen in Figure 1, may be a polyest ⁇ er film of approximately .0002 inch thickness. For ex ⁇ ample, this may be 20C Mylar, trademark Dupont.
  • the film 18 serves several purposes: it is substan ⁇ tially impervious to moisture, and, in conjunction with the heat sealable coating, it bonds to the glass fiber mesh fabric 12 to protect the glass fiber mesh against abrasion and wear.
  • the film 18 and the coating layer 16 prevent self-abrasion by shifting movement of the glass fiber mesh 12 in use, by substantially fixing the individual glass fibers in place and preventing them from deleterious wear against one another, which over time will break the brittle fibers.
  • the film layer 18 also prevents abrasion of the glass fibers of the mesh 12 by adjacent materials on the film side of the fire barrier material 10. Importantly, the thin film 18 (and the coating 16) do not alter the fire resistant character of the glass fiber fabric 12.
  • the invention also encompasses the lamination of the scrim webbing 14 to a glass fiber mesh fabric 12 (such as by heat seal adhesion), without the thin film 18.
  • a lamina ⁇ tion still provides an advantageous fire barrier product having the qualities of being very thin, flexible, not creasing when wrinkled, light in weight, tear resistant and wear resistant to some degree.
  • the scrim webbing 14 provides some wear resistance on one side, and the use of adhesive still has some beneficial effect in tending to fix individual glass fibers in place, reducing self-abrasion.
  • the invention in its broadest aspects also encompasses a lamination as shown in Figures 1 and 3 but without the scrim webbing 14.
  • a laminate fire barrier has sub-
  • SUBSTITUTESHEET stantially all the qualities listed above for the preferred embodiment, but with less tear resistance.
  • a fire barrier product in accordance with the invention can also have additional elements.
  • the scrim webbing 14, adhesive layer 16 and thin film 18 can be laminated to the upper side of the glass fiber fabric 12 (as viewed in Figure 1), in addition to being laminated to the lower side as shown.
  • a fire break laminate material comprises a central glass fiber fabric 12 r surrounded by a reinforcing scrim webbing 14 on either side and with outer layers of protective, substantially moisture-impervious thin film 18 adhered to the composite laminate at both outer surfaces.
  • the glass fiber fabric 12 can be replaced with a fabric of ceramic fibers.
  • the laminated products of the present invention provide a fire barrier combined with an extremely lightweight, reinforced insulation covering.
  • these fire barrier laminates possess excellent moisture resistant, wear resistant, tear resistant, crease resistant and fire blocking properties.
  • the film surface of the fire barrier laminates presents excellent resistance to chemicals, solvents and petroleum products, and the laminate materials have excellent sewing characteristics.
  • Flammability Zero flame time , zero glow tine per FAR Part 25, App. No drippings Vertical Burn Length Less than 5 inches

Abstract

Le matériau pare-feu léger décrit (10) comprend une toile en fibre de verre tissée doublée sur au moins l'un de ses côtés d'une membrane ou d'un film mince et dur (18) ayant de préférence un faible coefficient de friction et une bonne résistance à l'abrasion. Le film ou la membrane est maintenue contre la toile résistante au feu au moyen d'un adhésif (16) et sert à bloquer ou à geler les fibres de verre en position, enfin d'empêcher l'auto-abrasion des fibres entre elles. Cette structure stratifiée peut être renforcée par un grillage de renforcement à canevas léger (14) collé entre la toile résistante au feu et le film ou la membrane. Le produit pare-feu ainsi obtenu résiste, en cas d'incendie, à l'avance des flammes pendant une période appréciable, en particulier lorsqu'il est utilisé dans des avions. Un tel produit est particulièrement utile comme cloison pare-feu pour le confinement de parois de cabines d'aéronefs.
