Definitions

  • the present invention relates to a particular kind of wire comprising an outer mantle realized in metallic material and an inner portion comprising fibers, to be used autonomously or for the creation of strands or ropes, characterized by advantageous mass-resistance ratio.
  • a strand-like material composite comprising : carbon nanotubes (CNT) yarns; a metallic component enveloping the CNT yarns to form the material composite, the material composite having a cross section, the metallic component being in the form of a matrix which spans the cross section of the material composite, wherein the CNT yarns occupy 4 to 10% by volume of the material composite.
  • CNT carbon nanotubes
  • the aspects linked to the specific weight of the materials is yet significant; it is in fact clear that the effect of weight reduction of the weight linked to the floatation push is, in percentage, as greater as the specific weight of the used materials is lower.
  • a possible solution for re-dimensioning the problems linked to the high specific weight of the construction materials lies in the possibility to use materials other than metals, as for example fibers: a constructive choice of this kind leads to the realization of a wire with highly developed mechanical features, thus guaranteeing a drastic reduction of the final product weight.
  • Aim of the present invention is to provide a solution which is able to overcome the main problems of specific weight, efficiency and heat resistance, peculiar to the state of the art, by means of a device which can optimize the ratio between mass and resistance thus preserving the inner fiber performance.
  • Another aim of the present invention is to provide a device which can be used differently in relation to the material kind in the constructive phase and in relation to the kind of treatment received.
  • the aim is solved by means of a new kind of composite wire, characterized by an outer mantle in metallic material and an inner portion comprising fibers and/or pultruded bars, able to conjugate the constructive advantages deriving from the use of these latter, and avoiding as well the problems in terms of wear exposure and damages by means of a protective coating mantle.
  • object of the present invention is a particular and innovative kind of composite wire 10, having an outer mantle 1 in metallic material with protective functions, and an inner portion comprising fibers 2, able to overcome the problems linked to the specific weight and little resistance to high temperatures and pressures at the state of the art, and characterized by an advantageous mass-resistance ratio.
  • Figures 4 to 7 represent tridimensional views of preferred embodiments of the invention, some of them being made up of only two layers, i.e. a linear ( figures 4 and 6 ) or helical ( figure 7 ) outer mantle l in metallic material, and an inner portion comprising fibers 2 arranged in parallel bundles ( figures 4 and 7 ) or twisted around each other ( figure 6 ), the other one comprising also another inner portion represented by a pultruded bar 3 ( figure 5 ).
  • the use for example of a bar in glass fiber 3 as innermost portion of the wire 10 ( figures 2 and 5 ) contributes sensibly to implement its features of resistance and of high temperatures and transversal pressures bearing.
  • the axial and transversal, dimensional and resistance features as well as the elasticity of the composite wire 10 can be differently modulated using metal outer mantle 1 with different resistance, diameter or thickness, possibly helically wound as well, in turn in variable combination with different combinations of fibers 2 and/or pultruded bars 3, which can be used in parallel or helical bundles ( figures 4 to 7 ) as well.
  • the external features of corrosion resistance of the wire 10 can be differently determined by choosing materials for the realization of the outer mantle 1, as well as the respective superficial finishing with the longitudinal edges to be welded; in this last case, considering all the other features for certain, an increase of the torsional resistance of the wire 10 can be detected.
  • said composite wires 10 can be used autonomously, as long as they are provided with specific ends or connections, or they can constitute portions of the bundles, strands 12 ( figure 1 ), these ones also being compacted ( figure 2 ), or of ropes 13 made up of said strands 12 ( figure 3 ).
  • said wire can be also used as vehicle for conducting electric energy, using fibers 2 coated with an aluminum mantle 1 : such a possibility would allow to solve many problems linked to the weight and the high thermal expansion of the solutions currently available, which are mainly characterized by the use of steel and aluminum cables.
