Definitions

  • the present invention relates to filiform elements, called fibers, which can be used for reinforcing moldable materials with a binder of the hydraulic type or not.
  • fiber reinforcement provides an increase in the breaking energy of the composite material compared to the brittle matrix material.
  • the increase in energy required for breaking corresponds to the energy required for lengthening and breaking the fibrous reinforcement.
  • the behavior of the fiber depends on the behavior of the hooks in the matrix.
  • Fibers with sinusoidal undulations distributed over their entire length are Fibers with sinusoidal undulations distributed over their entire length.
  • the unfolding energy is again much lower than the breaking energy by traction of the fiber; the number of undulations along a fiber does not compensate for the too large radius of curvature of each undulation.
  • Straight smooth fibers comprising in their length flattened parts which can also be located at their ends.
  • the matrix can be sheared by the flattened parts, resulting in harmful loosening.
  • the breaking energy of the composite material would be that of the fragile matrix, increased by that of the fibrous reinforcement.
  • the present invention relates to a steel fiber for example, intended to reinforce a matrix material, concrete for example by never removing shoes from it, neither because of the fiber itself, nor because of the matrix by breaking thereof in the vicinity of 1 'the anchor.
  • the reinforcing fiber comprises at each end according to the invention an anchoring device consisting of one or more volumes of any shape whose all transverse dimensions are greater than the diameter of the filiform body.
  • the anchoring device can be constituted at each end of a single volume called the head, which can have a shape which is increasingly swollen towards the ends of the fiber and even have a part with symmetry of revolution.
  • the generating curve of this solid of revolution can be such that the intersection of the tangent at any point of this curve with the external lateral surface of the filiform body of the fiber is always in the very volume of the head; the heads can however also be partly or entirely of cylindrical shape.
  • the desired fiber must have a filiform body provided at each of its ends with a head whose internal part, that is to say the part in contact with the filiform body, is of solid form of revolution such that the angle between the tangent at any point of the generating curve and the axis of the filiform body has a maximum value between - 20 and 60 °.
  • the value of this angle will depend, to obtain the ideal behavior, on the nature of the material constituting the fiber.
  • steel for increasingly weak mechanical qualities requires increasingly higher head angles and for increasingly high mechanical qualities requires increasingly weak head angles.
  • the filiform elements called "fibers” described above can be manufactured by the use of several methods.
  • a filiform element of indefinite length with a diameter equal to the largest transverse dimension of the head is subjected, by passage between a pair of grooved rolling cylinders, the grooves of which are provided with notches spaced from one another. , a reduction of dia meter over its entire length except that heads are formed at the locations of the notches cut along the grooves of the rolling rolls.
  • the next step in this process is to regularly cut the continuous laminated filamentary member to produce fibers of precise length with a head at each end.
  • Another method is carried out by striking a hammer on each end of a filiform element, without a head, having a diameter equal to that of the body of the fiber, each end being maintained during striking by a matrix so as to obtain a head of desired shape.
  • a third process is carried out by forming a drop at the ends of the filiform body at a temperature close to the melting point of the constituent material. After this forming, it can be quenched to improve the mechanical qualities of the fiber.
  • the wound wire generally designated by the reference notation 1 is drawn towards a rolling apparatus 2 consisting of a pair of fluted rolling cylinders regularly provided over their length with matrix slots of the fiber heads, of which FIGS. 7 and 8 give an example so as to reduce the diameter of the wire as a base material up to the diameter of the filiform body of the fiber except at the location of the heads of these fibers.
  • This rolling apparatus 2 provides a wire of diameter smaller than the initial diameter and provided with regular spacing of swellings.
  • the shearing device 4 cuts the wire thus obtained at mid-volume of each swelling to create the fibers provided with their heads.
  • the wound wire generally designated by the reference numeral 1 is drawn towards a shearing apparatus producing straight filiform elements 6 of short constant length which must be gripped individually, pinched at their ends between two dies, as in figure 9, generating with the help of hammers striking the desired heads in their exact form.
