Description

The present invention is characterized by the ratio of the advantageous mass and resistance, alone, or strands (strand) or used to form the rope, the outer mantle (mantle) and textiles realized in metallic material It relates to a specific type of wire with an interior that contains .

An example known in the prior art is application number US2010 / 330365. In this document,
A strand-like composite material including carbon nanotube (CNT) spun yarn is described, and a metal element covers the CNT spun yarn to form a composite material, the composite material has a cross section, and the metal element material is The shape of the base material extends across the cross section of the composite material, and the CNT spun yarn accounts for 4% to 10% of the composite material volume.

In the prior art, different types of wires or strands and ropes obtained from the wires are currently known. And it is all realized with steel or other metallic materials and has certain advantages, for example:
-High axial resistance.
-High lateral load resistance.
-High environmental resistance.
-High corrosion resistance.

The device has the following major drawbacks as well, for example.
-There is little resistance to fire or, more generally, exposure to high temperatures, at the expense of significant metal resistance.
-A large material specific gravity that inevitably leads to the high weight of the entire product realized with this specific gravity.

  This latter aspect represents the most important drawback of the known device. In fact, especially when vertical extension structures are mentioned (eg as cableways, offshore cranes, drift mines, etc.), in the case of much higher and larger structures, the single unit used to withstand the load The weight of the member must be taken into account.

  Also, if the device is intended for use in water, hydrostatic pressure is obtained where the overall weight of the device is reduced to the order of 13%, but aspects related to material specific gravity are still important. In fact, it is clear that the weight reduction effect associated with buoyancy is the same in proportion, even when the specific gravity of the material used is smaller. As a possible solution to the resizing associated with the large specific gravity of the structural material, it is possible to use materials other than metal, for example fibers. This type of structure selection leads to the realization of wires with highly developed mechanical properties and thus guarantees a significant reduction in the final product weight.

However, it is impossible to realize a rope or strand made entirely of fibers. In fact, even if it is certainly highly developed mechanical properties of the material, wire, strands, and in the realization of the rope, that would prevent the use of textiles as a single structural materials, for example, the following important There are more points.
-Problems associated with rapid wear.
-Vulnerability to axial stress.
-Greater exposure due to metal material damage.
-Little possible damage is detected.

  The object of the present invention is to provide a solution that can solve the main problems of specific gravity, efficiency, and heat resistance unique to the prior art by means of an apparatus that can optimize the ratio of mass and resistance and maintain the performance of the internal fibers. That is.

  Another object of the present invention is to provide an apparatus that can be used differently with respect to the type of material in the structural state and with respect to the type of treatment being applied.

  The object is solved by a new type of composite wire characterized by an outer mantle of metallic material and an interior with fibers and / or pultruded rods, which can take advantage of the structural advantages obtained by the use of these latter, The protective covering mantle further avoids problems related to wear exposure and damage.

  These and other features of the present invention will be emphasized in the following description of preferred embodiments with reference to Figures 1/3, 2/3, and 3/3.

FIG. 3 is a cross-sectional view of a preferred embodiment of a strand comprising several wires, each wire characterized by an interior comprising a metallic outer mantle and fibers. Of a strand comprising several wires characterized by a metallic outer mantle, a first inner layer of fibers, and a second inner layer represented by a pultruded rod, after each wire has undergone a total compression treatment 1 is a cross-sectional view of a preferred embodiment. FIG. 3 is a cross-sectional view of a preferred embodiment of a rope with each wire having an interior that includes a metallic outer mantle and fibers , each strand is characterized by several wires and is arranged in sequence . 3 is a three-dimensional view of a preferred embodiment of a wire characterized by an interior comprising a linear outer mantle of metallic material and fibers arranged in parallel bundles. Three-dimensional view of a preferred embodiment of the wire characterized by a second inner portion which includes a first inner portion, and a pultrusion rods comprising linear outer mantle of a metal material, the fibers arranged in parallel bundles . FIG. 3 is a three-dimensional view of a preferred embodiment of a wire characterized by an interior comprising a linear outer mantle of metallic material and fibers wrapped around each other . FIG. 3 is a three-dimensional view of a preferred embodiment of a wire characterized by an interior comprising a spiral outer mantle of metallic material and fibers arranged in parallel bundles.

As described above, the object of the present invention is to overcome the problems related to the specific gravity and the vulnerability to high temperature and high pressure in the conventional example, and to have a protective function characterized by an advantageous mass-to-resistance ratio. A particular innovative type of composite wire having an outer mantle 1 and an interior containing fibers 2.

  By using the outer mantle 1 realized by a metal material, it is possible to eliminate damage and vulnerability to the problem of lateral load unique to the fiber 2.

Similarly, by introducing the interior including the fibers 2 and / or the pultruded rods 3, the following significant advantages can be obtained, for example.
A significant reduction in the specific gravity of the structural material (for example in a possible preferred embodiment of the wire 10 40% is made of steel and the remaining 60% is made of high-resistant fibers with a specific gravity of about 1.4; (The final device has a specific gravity corresponding to 50% of the specific gravity of water or 40% in water.)
-Higher fire resistance.
-Higher resistance at high temperatures, especially when the composite wire 10 contains the core inside the glass fiber 3;
The possibility of delaying the internal temperature rise of the wire 10 when exposed to high temperatures for a long time.
-Contribution to the overall load capacity.

4-7 represent three dimensional views of a preferred embodiment of the present invention. Some of them consist of only two layers. That is, the outer mantle 1 made of a metal material having a linear shape (FIGS. 4 and 6) or a spiral shape (FIG. 7) and a parallel bundle shape (FIGS. 4 and 7) or wound around each other (FIG. 6). Only the inside including the fibers 2 arranged in (). The other one also comprises another interior represented by the pultruded rod 3 (FIG. 5). For example, the wire 10 using a rod glass fiber 3 as the most inner part of the (FIGS. 2 and 5) contributes significantly to confer resistance and high temperature and lateral compression load characteristics of the.

Obviously, the axial and lateral dimensions and resistance characteristics, as well as the elasticity of the composite wire 10, are made of a metal that has different resistances, diameters, or thicknesses and, if possible, is further helically bent . The outer mantle 1 can be used to adjust differently by sequentially changing the combinations with different combinations of fibers 2 and / or pultruded rods 3 that can be used for further parallel or helical bundles (FIGS. 4 to 7).

Further, the outer characteristics regarding the corrosion resistance of the wire 10 may be determined differently depending on the material selection for realizing the outer mantle 1, regardless of the presence or absence of welding of the edge portion in the major axis direction, similarly to the respective surface finishes. . In this last case, all other features can be reliably taken into account and an increase in torsional resistance of the wire 10 can be detected.

  Finally, the different ways of treating and impregnating the fibers 2 (resins, lubricants, buffers) contribute to other implications of the materials used.

  As described above, the composite wire 10 may be used alone as long as a specific end or connection is provided, or the strand 12 (FIG. 1) that is part of a bundle. These strands may also be compressed or may form part of the rope 13 consisting of the strands 12 (FIG. 3) described above.

  Given these characteristics of lightness and resistance specific to the subject of the present invention, in all areas where aspects related to the specific gravity of the various elements are particularly important (offshore deep seas, mine shafts, aviation, construction) Obviously, it is primarily intended for use of the device. However, the above use represents a preferred use possibility and does not exclude other possible and appropriate uses.

In particular, it should be emphasized that the wire can also be used as a means of conducting electrical energy using fibers 2 coated with an aluminum mantle 1 . This possibility solves many of the problems associated with weight and thermal expansion for currently available solutions primarily characterized by the use of steel and aluminum cables.

  Only a portion of the preferred embodiments of the present invention have been described. It is intended that modifications and / or variations can be made without departing from the spirit of the invention as defined by the following claims.
