Definitions

  • the invention relates to a device for producing a fiber composite component and to a method for producing a fiber composite component with such a device.
  • the invention has for its object to provide an aforementioned device and an aforementioned method with which problems of the prior art can be achieved and in particular it is possible to produce fiber composite components very quickly in consistently high and accurate quality with the lowest possible machinery.
  • the device has at least a first part form and a second part form, which together form the shape for the fiber composite component. There may also be provided more sub-forms than only these two, but it is advantageous two.
  • the two partial shapes have inner sides, each with an inner contour, facing each other during production of the fiber composite component.
  • the inner contours form an interior of the mold consisting of the two partial shapes, wherein this interior is advantageously relatively flat or particularly advantageously has a relatively small thickness, which should not exceed 10 mm or more than 20 mm. This means that the fiber-composite component to be produced can be curved or can have another form deviating from the planar shape, but not too large Thickness, even if this should be given only in certain areas. For one thing, a lot of material is needed for that.
  • the inner sides of the part shapes are just facing each other.
  • the partial shapes are circumferentially around and largely closing or closed to each other. They are connected by means of connection, which will be discussed in more detail later.
  • a resin supply is provided which leads from the outside into the interior.
  • resin removal from the interior is also provided, which, on the one hand, naturally allows air and, on the other hand, excess resin to escape from the interior.

This is procedurally well controlled and allows a cost-effective and rapid production of such forms or the corresponding part shapes.
  • An embodiment of the part shapes as disposable parts has the great advantage that the molds or part shapes then no longer need to be cleaned consuming after removing the finished fiber composite components.
  • the provision of bonding means on the part molds enables the dies no longer to remain in the press apparatus after curing of the part molds together to form the fiber composite member and curing to cure the resin for the fiber material until the resin is cured which takes a few minutes, typically 5min to 20min.
  • the mold with the fiber material and resin can be removed from it much earlier in the press, for example, even if the resin just begins to gel. After pressing in the resin-introduced press, all air should be removed from the fiber material and from the entire mold. Because the fiber material itself is usually quite soft or flexible, there are no major forces in not yet cured resin, which act on the mold or the part shapes and could cause deformation again.
  • the two partial shapes are formed substantially square in plan view of their essential surface.

  • a distance of the inner contour to the edge regions may be a few centimeters, for example 1 cm to 5 cm.
  • the tool or the mold is tight or even vacuum-tight. This allows air pockets to be minimized when introducing resin.
  • this can also be done by pressing or pressing in an autoclave.
  • Sealant or a seal may be formed circumferentially. It can generally be inserted as a separate part in the part shapes, alternatively it can be molded on.
  • a circumferential seal need not be a seal in the classical sense, so with additional elastic or elastic material, but can alternatively be created by welding the two part shapes, which of course also seals obviously. Then there is a disposable concept, since the part forms must be destroyed to remove the finished component.
  • the inner sides of the part shapes are formed corresponding to each other.
  • a distance between these inner sides can be between 1 mm and 10 mm in the assembled state of the two partial shapes.
  • the distance is in At least 50% of the inner sides between 1 mm and 3mm, which then gives the thickness of the finished fiber composite component.

In a second stage, they are then firmly or maximally compressed. Due to the automatic connection, no manual or additional work step is necessary, which would be difficult to carry out, for example, in a pressing device. Thus, the part shapes can only be compressed in the final position in the pressing device.
