Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/796,395, filed May 1, 2006, which is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The present invention relates generally to insulating materials, and more particularly to insulating materials and tubular sleeves constructed at least partially from basalt continuous filaments.
- 2. Related Art
- Automotive, aeronautical, rail and marine components positioned in engine compartments or near heat sources such as exhaust manifolds may be subjected to harsh thermal environments. Further, undesired heat transfer may also occur between heat sources such as engines, exhaust systems and/or transmissions and the passenger compartment of an automobile, aircraft, train or boat. Oil and gas exploration and drilling tools also need protection from exposure to heat and spark and fire. It is known in the art to use insulating materials to form insulating panels or sleeves to reduce heat transfer from a heat source to other adjacent components. The insulating materials must be suitable for their intended use and are subject to testing under extreme conditions to insure their suitability. In the aerospace industry, for example, where temperature deviations are extremely large and components are unusually sensitive to temperature, the insulating materials must be capable of protecting components from especially harsh environments and conditions. These harsh environments may include exposure to open flames, so it is also beneficial if the insulating material is fire-resistant.
- The prior art is replete with materials that are used as a heat insulating layer of such panels. For example, it is known to use various fibrous materials, and compositions of the same, to act as an insulating material of such panels or sleeves. Mineral fibers, such as fiberglass, silica, basalt and ceramic fibers are all known in the art as insulating materials. Each of these materials has different characteristics, for example, different physical and mechanical properties, operating temperature limits, thermal properties and chemical resistance, that make each material better suited for certain applications.
- Modern engines run at higher temperatures than engines of several years ago and, accordingly, heat insulating materials for the modern engines are required to perform under more demanding conditions than those used in even the recent past. Some modern applications require protection to components in extreme temperatures that some of the prior art materials are incapable of providing. Thus, motor vehicle, aeronautical, train and boat manufacturers are required to use newer and more robust materials to provide adequate performance for such applications. Furthermore, many new demanding applications requiring protection against extreme heat have emerged due to the increased use of heat sensitive components (e.g., sensors) in close proximity to heat generating or conducting bodies.
- A textile insulating material is fabricated at least in part from a plurality of texturized basalt continuous filaments. In accordance with various aspects of the invention, the texturized basalt continuous filaments can be knitted, woven and/or braided into a fabric, sleeve or other construction suited for the intended use. The fabric, sleeve or other construction can be coated with high temperature coatings, such as acrylic, polyester, urethane, epoxy, silicone and the like.
- According to another aspect of the invention, a textile insulating material can be fabricated with a plurality of twisted basalt continuous filaments. The twisted basalt continuous filaments may, similarly to that of the texturized basalt continuous filaments mentioned above, be knitted, woven or braided into a fabric, sleeve or other construction suited for the intended use. The fabric, sleeve or other construction may be coated with high temperature coatings, such as acrylic, polyester, urethane, epoxy, silicone and the like.
- In view of the above, the insulating materials fabricated in accordance with the invention have robust performance characteristics and are capable of providing protection to temperature sensitive components against extreme temperatures. The materials are also easily manipulated and capable of wide use throughout a vehicle by, for example, being capable of taking various shapes, and be formed into resilient constructions. In addition, the materials are generally economical in design, manufacture and use. The materials of the invention will find application in any of a number of fields including, without limitation, automotive, marine, aeronautical, train, and oil and gas exploration and drilling equipment.
- Further scope of applicability of the present invention will become apparent from the following detailed description and claims. However, it should be understood that the detailed description and specific examples, while indicating presently preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
- These and other aspects, features and advantages of this invention will become readily appreciated when considered in connection with the detailed description of presently preferred embodiments and best mode, appended claims and accompanying drawings, in which:
-
FIG. 1 is partial cross-sectional view of a textile material constructed using a plurality of basalt continuous filaments in accordance with one presently preferred embodiment of the present invention; -
FIG. 2 is a fragmentary perspective view of a tubular closed wall textile sleeve constructed using a plurality of basalt continuous filaments in accordance with another presently preferred embodiment of the present invention; -
FIG. 3 is a fragmentary perspective view of a tubular open wall textile sleeve constructed using a plurality of basalt continuous filaments in accordance with another presently preferred embodiment of the present invention; and -
FIG. 4 is a fragmentary perspective view of another tubular textile sleeve constructed using a plurality of basalt continuous filaments in accordance with another presently preferred embodiment of the present invention. - Referring in more detail to the drawings,
FIG. 1 illustrates atextile insulating material 10 constructed from a plurality of basaltcontinuous filaments 12 in accordance with one presently preferred embodiment of the invention. The basaltcontinuous filaments 12 are fire-resistant and can provide thermal protection against extremely high (e.g., 760° C.) and extremely low temperatures (e.g., −260° C.) as well. A fabric sheet, panel, sleeve or other construction fabricated with the interlacedcontinuous basalt filaments 12 in accordance with the invention is superior to, and may be used to supplement or replace, many insulating and fire-resistant materials in use today. As non-limiting examples,sleeves FIGS. 2-4 , respectively, wherein thesleeves continuous filaments 12 and, thus, may be used to insulate pipes exposed to extremely high heat (such as exhaust pipes having temperatures of 500° C. to 760° C.) or insulate cryogenic pipes or tanks (such as liquid nitrogen or compressed natural gas tanks, which may reach temperatures as low as −191° C. and −161° C., respectively), for example. - According to one aspect of the present invention, a plurality of the basalt
continuous filaments 12 are arranged to form a yarn or yarn-like strand 18. In one presently preferred embodiment, the yarn-like strand 18 is texturized to increase the volume of thestrand 18 and create air pockets within the body of thestrand 18. By texturizing the basaltcontinuous filament yarn 18, it can provide enhanced thermal protection with a reduced weight yarn, while also providing enhanced acoustic properties. In one presently preferred embodiment, the strand ofyarn 18 is air-texturized and has a density of about 1800 tex. In another presently preferred embodiment, the strand ofyarn 18 is subjected to a draw texturization rather than an air texturization. As such, theyarn 18 can be texturized to achieve any suitable density. Generally speaking,finer yarns 18 are used to make more flexible materials andheavier yarns 18 are used to provide increased coverage. Therefore, the choice of the yarn density, and the selection of the basalt filaments to be used depends on the type of material being constructed and the intended application for the resulting material. In yet another presently preferred embodiment, the strand ofyarn 18 is twisted, instead of being texturized. In this construction, theyarn 18 has a density of about 260 tex and is twisted to 120 turns per meter, although any strand density and turns per meter may be used depending on the desired application. It has been found that the abrasion resistance of the insulating material increases as the degree of twisting increases. In yet another presently preferred embodiment, thestrand 18 is first texturized, and then twisted. Many of these texturized and/or twisted basaltcontinuous filament yarns 18 are created and utilized to construct an insulating material of unitary construction, as described more fully below. - Having obtained a number of the basalt continuous filament strands of
yarn 18, thestrands 18 are then arranged in a configuration to create the desired structure of insulating material. In one embodiment, thestrands 18 are woven to create theinsulating material 10 orsleeves strands 18, including but not limited to knitting, weaving, sewing, crocheting, embroidering and braiding. Depending on the application, one or more of the aforementioned methods of construction may be preferred. For example, in some instances, a braided texturized basalt continuous filament sleeve may be preferred for its ability to attain greater coverage and lighter weight. - Furthermore, the insulating
textile material 10 may formed in any configuration, including but not limited to thetextile fabric 10 andsleeves sleeves FIG. 2 ), or an open wall 20 (FIG. 3 ) construction withlongitudinal edges sleeve 15. Further, thesleeves FIG. 4 , the insulatingsleeve 16 may be created as a single layer knitted sleeve folded back onto itself to form the twolayers sleeve 16, or a single layer knitted sleeve may be folded back and forth on itself to form the multi-layer sleeve. In addition, any of thesleeves FIG. 2 , that contains pigments if a color other than that of natural basalt is desired. - According to another aspect of the invention, layers, such as represented generally at 23 in
FIG. 1 , for example, in addition to the insulatinglayers 20 constructed of basalt continuous filament, may be present on thematerial 10 orsleeves additional layers 23 may include, for example, silicone, rubber, aluminum or other metal, epoxy, carbon-fiber, ceramic and plastic, or compositions thereof. As such, the insulatingsleeves continuous filaments 20 with thelayer 23, for example, a silicone-rubber coating, applied to an exterior surface of the insulatingmaterial 20. In addition to the aforementioned material layers, other types of material layers may be used, such as in an application suitable for use of the described insulatingmaterial 10 andsleeves material 10 and/orsleeves FIG. 3 . Theintumescent coating 25 can be adhered to the material 10 orsleeves continuous filament sleeve intumescent coating 25 may be applied to only the outer-most surface of thesleeves material 10, or to all surfaces if desired. - The insulating and fire-
resistant material 10 andsleeves sleeves continuous filament yarn 18 may be used to insulate exhaust pipes to prevent extremely high heat produced by the exhaust pipe from damaging nearby temperature sensitive components in the vehicle. A knitted construction of thesleeve sleeve continuous filament yarn 18 may be texturized or twisted, with the texturized version being preferred in many applications. - The foregoing discussion discloses and describes an exemplary embodiment of the present invention.
