  • a method of manufacturing a fiber-metal composite has been known in which a fiber preform housed in a cassette and a filler metal are placed in an annular groove between two metal workpieces.
  • the metallic workpieces are bonded to the fiber preform and the filler metal by heat and pressure or diffusion bonding.

  • the workpiece is plastically deformed by means of the machining device.
  • the transformations are three-dimensional changes in the shape of the workpiece which are suitable for producing a non-positive and / or positive connection with a fiber layer, i.
  • the deformations should typically protrude beyond the workpiece plane in a plate-shaped workpiece or protrude from this.
  • the attachment of the fiber fabric to the workpiece preferably takes place in a form-fitting manner or in such a way that the fiber layer can be displaced together with the workpiece in the working plane after installation, without causing a relative movement between the workpiece and the fiber layer.
  • recesses provided on a fiber mat can be brought into engagement with the deformations and / or the geometry of the fiber mat can be adapted such that it fits in a form-fitting manner between the deformations.
  • the non-positive and / or positive connection can in this case take place on that machine tool which is also used to produce the deformations in the workpiece, so that a transfer of the workpiece between the forming machining of the workpiece and the bonding process between the workpiece and fiber layer is not required.
  • the inventive method thus enables automated production of a Fiber-metal composite workpiece in a single operation, so that by means of the method according to the invention fiber-metal composite workpieces can be produced in an economical and highly resilient manner.
  • a stamped machining of the workpiece for generating the deformations before and / or during non-positive and / or positive connection of the Fasergeleges with the workpiece.
  • transformations e.g. In the form of passages (round recesses whose edges are still formed at the top or bottom), beads (channel-shaped depressions), gills (beads with opening), etc. are generated. It is understood that the enumeration given here is not exhaustive, i. E. Other than the listed here types of transformations can be used to produce a positive and / or positive connection between the workpiece and the fiber fabric.

  • the step of applying the fiber fabric comprises feeding at least a portion of the fiber fabric in the form of a fiber mat to the resting on the workpiece support workpiece.
  • the fiber mat can be cut out, for example, from a fiber fabric or produced in embroidery technology. In the latter case, it can be a two-dimensional fiber fabric produced on a textile machine, in which fiber rovings are placed on a base of embroidery and, e.g. be attached to the embroidery ground by zigzag stitches.

  • the fiber mat is fixed to the workpiece and can be moved in the working plane (X / Y direction) together with the workpiece, without slipping. This is beneficial for subsequent (forming) machining to make a permanent bond between the workpiece and fiber web, since the workpiece must typically be displaced in the working plane to make the permanent connection to allow reshaping of the deformations.
  • the slippage of the workpiece can possibly also be avoided if the fiber mat has no recesses or openings, but an outer edge whose shape and size is adapted to the contour of a region on the workpiece, which is limited by several transformations. Also in this case, a positive connection or fixation can take place, which allows a joint movement of the workpiece and fiber layer. It is also possible, before attaching the fiber fabric to the workpiece pointed deformations, for example in the form of prongs to provide that prick when attaching the fiber fabric through this and thus prevent mutual slippage. During subsequent joining or forming machining these tines can be bent and pressed flat, the fibers are clamped and creates a positive connection.

  • the fiber strands are preferably supplied to the workpiece located on the workpiece support by transport from a magazine, for example by unwinding from a coil.
  • the transport comprises a feed movement of the fiber strands from the magazine, which can be realized by means of a drive, e.g. by means of a motor for unwinding the spool.

  • the fiber strands transported to the workpiece can be attached to the workpiece by means of an application device in the area of the deformations, or these can be wrapped with the aid of the application device.

  • the non-positive and / or positive connection of the fiber fabric with the workpiece comprises a deformation of the deformations generated on the workpiece.
  • the deformation of the deformations causes e.g. when using a fiber mat, that the transformations engage over the recesses in the fiber mat or clamp the fiber mat, so that the fiber mat can no longer be separated without damage from the workpiece and thus the fiber mat whose recesses were previously brought into engagement with the transformations to the workpiece is permanently fixed (joining by forming).
  • the fiber mat and / or the fiber layer formed by wrapping the deformations can be clamped by the forming machining on the deformations with the workpiece.

  • connection of the fiber mat 16 with the workpiece 2 can be done as described above in the region of the transformations 15, which also serve to fix the fiber mat 16 in the x-y direction. In this way, a form-locking connection of the workpiece fiber-covering cover sheet sandwich is achieved.
  • Umformungen not shown
  • the connection between the workpiece 2 and the fiber mat 16 can additionally or exclusively be carried out by means of these further deformations which are preferably formed adjacent to the fiber mat 16 on the workpiece 2 and which after forming or deformation at least partially overlap the workpiece surface covered by the fiber mat 16.
  • the fiber mat 16 and any cover plate may be formed together, eg in the form of a bead, to produce in this way a force and form fit.
  • FIGS. 5a, b and the FIGS. 6a, b shown procedure for non-positive and / or positive connection of fiber mat 16 and workpiece 2 can be applied analogously to the non-positive and / or positive connection of the workpiece 2 and made of fiber rovings fiber fabric. It is also understood that portions of the fiber fabric can be formed as fiber mats and other portions in the form of fiber rovings.
  • the fiber-metal composite is cut out of the workpiece 2 along a cutting contour 19 in a final processing step. This can be done by laser cutting through the laser processing head 4 or possibly by nibbling with the aid of the punching head 3.
  • the finished fiber-metal composite piece 23 (see. Fig. 7 ) can then be discharged from the machine tool 1 by means of a transport device, not shown pictorially.
  • this processing step may possibly be made elsewhere. This may be favorable if the manufacturing process described above is not as in Fig. 1 shown at a laser punching combination machine 1, but for the production of the composite workpiece 23 a punching machine is used without laser cutting function.
  • Fiber-to-metal composites 23 made in the manner described above may be used in further processing steps e.g. formed by bending three-dimensionally and then in a tool e.g. Resin Transfer Molding (RTM) process is infiltrated with resin or overmoulded with a thermoplastic material.
  • RTM Resin Transfer Molding
  • the composite is realized by a direct power transmission between the sheet and fibers by force and / or positive connection.
  • Both the machining of the metallic workpiece and the connection of the workpiece to the fiber web can be carried out in one and the same machine tool, i. the cutting of the sheet metal part, the joining of the workpiece with the fiber fabric and possibly also the production of the fiber fabric can be done in a single operation and thus fiber-metal composite workpieces are produced in a particularly economical manner.
