Definitions

  • the invention relates to a fiber-reinforced plastic molded part.
  • a fiber-reinforced plastic mold shows z. B. EP 0 531 840 B1.
  • a fiber malt provided with a binder from a resin-hardener system at a temperature at which the resin-hardener system behaves thermoplastic, preformed and then cured thermoset to the preform.
  • SMC molding compound UP resin, glass fiber reinforced
  • antennas here are generally transmitting and / or receiving antennas such.
  • the invention has for its object to save space with fiber-reinforced antennas To connect molded plastic parts.
  • this object is achieved in that the fiber-reinforced Plastic molding at least one antenna is integrated. This creates new designs possible e.g. B. in portable radio, television or cell phones.
  • the fibers are used to reinforce the molded part be used, an electrical conductivity.
  • the antenna is made of these fibers or the antennas are formed.
  • Carbon fibers have proven to be particularly useful since they are both have electrical conductivity as well as good tensile strength.
  • the molded part made of up to 60 percent by weight carbon fibers.
  • metal fibers preferably copper fibers (wires).
  • a fabric is pressed into the molded part, which in the warp or weft direction carbon fibers and / or metal fibers (wires), preferred Has copper fibers (wires).
  • the tissue is pressed in e.g. B. after processes specified in EP 0 531 840 B1.
  • the thickness and / or length of the fibers is selected depending on the required antenna tuning.
  • Conveniently are the carbon fibers and / or metal fibers (wires) in the fabric Spaced from each other. A distance of 5 mm has been found in tests proven advantageous. After contacting, there were good reception qualities in the Radio.
  • the fibers or the fabric are cured UP or vinyl ester resin coated. This can prevent any damage or displacement the fiber strands take place during further processing into the SMC molded part.
  • the molded parts described can be particularly advantageous with the integrated Arrange the antenna or antennas on a vehicle, e.g. B. in the trunk lid or in or on the bumper.
  • This Metal shielding is advantageously a synthetic vapor-coated with aluminum Fiber fabric or fleece.
  • the insertion of the antenna into the molded part can be done by weaving in as described the electrically conductive fibers or wires in the warp or weft direction in the Tissue. But it can also be sewn on (e.g. zigzag stitch) or Glue on the fabric.
  • FIG. 1 shows a top view of a carbon fiber laminate which forms a molded part 4.
  • the individual carbon fibers 1 are arranged in parallel at a distance of approximately 5 mm. If these carbon fibers 1 are contacted, an antenna can be formed from them.
  • FIG. 2a shows a fabric made of carbon fibers 1 with glass fibers 2.
  • the carbon fibers 1 are each arranged adjacent to a glass fiber 2 and vice versa, the fibers are arranged parallel and at a distance from each other.
  • Fig. 2b shows a fabric like Fig. 2a only the fabric is additionally pretreated here, so that the crossing points 5 are fixed. A fixed crossing point 5 is highlighted as an example in FIG. 2b.
  • This fabric is coated with hardened UP or vinyl ester resin. The dimensional stability is hereby achieved.
  • FIG. 3a shows a fabric 4 with carbon fibers 1.
  • the fabric here is as in FIG. 2b pre-treated.
  • 3b shows this fabric deformed and hardened. This is shown in FIG. 3c
  • the carbon fibers 1 in these Molded parts can then be used as antennas.
  • FIG. 4a, b show pressed-in receiving antennas in the primary molded part 3a (FIG. 4a) and in the secondary molding 3b (Fig. 4b).
  • the antenna is identified by reference number 7.
  • 5a, b show a similar arrangement, but for transmit antennas.
  • additional another metal-coated (preferably aluminum-coated) fabric 8 for Shielding provided.
  • the figures only show the arrangement of Antennas 7 in one form 3.
