Definitions

  • the erf ⁇ ndungssiee method for producing a shell body could, for example, have the method steps described below. At least two shell parts are produced from a fiber composite material, wherein each shell part has at least one boundary edge. At least one boundary edge of at least one compensation body made of a plastically deformable material is connected. In this case, for example, to each of the shell parts at each boundary edge such a compensating body be connected, it could be attached to each shell part only one compensation body, but it could also be connected to a shell part two balancing body, while attached to another shell part no such compensation body is. The thus prepared and equipped shell parts are overlapped with each other to form the shell body, so that surface seams arise between each adjacent shell parts, wherein the at least one balancing body is arranged on at least one of the seams.
  • Such a compensating body made of a plastically deformable material makes it possible to compensate for a deviation in shape between adjoining shell parts, in that the compensating body is mechanically changed in its shape.
  • the shell parts are designed, for example, as cylinder jacket segments whose boundary edges run parallel to the longitudinal axis of a resulting cylindrical shell body, these boundary edges could diverge lengthwise in the case of particularly large shell parts.
  • the shell parts would not touch flat and flush in the intended seam, so that would result in connecting the two shell parts in the seam and tension damage to the shell parts.
  • the plastically deformable compensating bodies would be very easy to correct in shape, so that a flat contact produced within the seam can be. As a result, tension and damage to the shell parts can be prevented.
  • the assembly work for the shell body can be reduced by the number of shell divisions is reduced. Ideally, it would be conceivable to assemble only two shell parts to form a shell body, whereby only two flat seams arise, in each of which at least one compensation body is arranged. However, the method according to the invention can also be extended to more composite shell parts, whereby the advantages according to the invention are not affected.
  • Shell parts also made possible in CFRP construction, so that the shell division can be reduced.
  • a two-shell design of a shell body is therefore quite easy to handle. Due to the larger shell parts made possible overall, a reduction of the assembly effort. Compared to conventional manufacturing process, the number of shell parts and thus of seams also reduces the number of stapling elements required for joining the shell parts due to the reduced number, so that this results in weight savings.
  • Another, particularly great advantage is that the power transmission between the interconnected shell parts is particularly good due to the flat seams and also homogeneous, compared with linear seams.
  • the compensating body is laminated into the fiber composite material of the relevant shell part.
  • the shell part made of a fiber composite material usually fiber mats or fiber fabric are associated with a matrix material, so that, for example, introduced in a boundary edge, a compensation body before curing of the fiber composite material and then after curing of the fiber composite material could be firmly connected to this.
  • the balancing body could have recesses, recesses or the like in a region which is enclosed by the fiber composite material. As a result, an improved adhesion of the compensation body could be achieved - similar to a wire reinforcement.
  • the compensation body could be brought to the affected shell part by a positive connection method.
  • any suitable recesses, rivets, bushes or the like could be provided on the shell part to allow the most ideal possible load introduction into the compensation body.
  • a plurality of compensation bodies is arranged on the shell parts, so that in each case at least one compensation body is arranged in all seams.
  • the compensation body could be designed as a fold-like element whose contour is continuous with the contour of the shell part. As a result, local structural load peaks can be reduced.
  • shell parts can be formed in an advantageous development of the method at least partially each as a cylinder shell segment, so that a compensation body could be realized, for example, as an elongated, strip-like extension to the boundary edges of the shell parts. This is particularly easy to manufacture and particularly easy to adjust in shape to correct form deviations.
  • the at least one compensating body could be produced from a metallic material.
  • a metallic material such as aluminum, copper, and other materials.
  • a shell part made of a fiber composite material having at least one boundary edge on which at least one compensating body made of a plastically deformable material at the at least one boundary edge arranged to compensate for deviations in form. From several such shell parts, for example, a shell body could be assembled. It would be possible to reduce the production costs but also that
  • Shell part is connected with two boundary edges and one compensating body at a boundary edge with a shell part, which has two boundary edges, but no own compensation body.
  • the adaptation of the shape deviations could be achieved accordingly by changes in shape of the compensation body of a shell part according to the invention.
  • the invention is achieved by a shell body made of a fiber composite material having at least one above shell part according to the invention.
