    Description
    Title of the invention: Fireproof cover using thermal insulation layers
    Technical Field This description relates generally to fluid conduits and flame retardant covers which can be used in connection with them, such as in aerospace applications.
    Context This general description is given below only for context establishment purposes. Thus, any aspect of this general description, insofar as it does not otherwise constitute a prior state of the art, is neither expressly nor implicitly admitted as being a prior state of the art with respect to the present invention.
    Fluid transport products, such as conduits, hoses, fittings, couplings and tubes, can be used in locations exposed to fire. In such applications, a fire protection mechanism can be used to ensure that the product does not fail (for example, to leak) during a specified period of time (for example, 5 to 15 minutes) under specified conditions. Some fire protection technologies include built-in silicone covers and silicone-coated fiberglass sleeves.
    In aerospace applications, as aircraft systems have evolved, fire test requirements have become more stringent, posing challenges to demonstrate compliance with existing fireproofing technologies. For example, some current fire blankets may not consistently meet the AS 1055 and TSO fire performance requirements that allow some fluid flow through the fluid carrier during testing, let alone the requirements without flow of AS1055 from new generation fluid transport products.
    There is a desire for solutions / options that minimize or eliminate one or more challenges or weaknesses of the fluid transport products, so as to meet more stringent requirements without flow. The foregoing discussion is intended only to illustrate examples in this area and should not be viewed as a disavowal of the scope.
    Summary [0006] In embodiments, a flame retardant blanket for fluid transport products can include an inner layer including a first polymer, an intermediate layer including a thermally insulating material, and / or an outer layer including a second polymer. The first polymer and / or the second polymer may include silicone. The first polymer and the second polymer may or may not be identical. One or more additional intermediate layers may be disposed at least partially between the inner layer and the outer layer. The intermediate layer can include fiberglass and can be arranged around the inner layer. The additional intermediate layer (s) may include (i) a first layer of basalt ribbon wrapped around the intermediate layer, (ii) a layer of fiberglass wrapped around the first layer of basalt ribbon, and (iii) a second layer of basalt ribbon wrapped around the layer of fiberglass. The outer layer may be disposed at an outer surface of the second layer of basalt ribbon.
