Definitions

  • the invention relates to a method for producing a fiber preform for the production of a fiber composite component having a predetermined geometry and outer end contour, wherein the fiber preform is formed from a fiber material.
  • the invention also relates to a manufacturing plant for this purpose.
  • fiber composite components Components made of a fiber composite material, so-called fiber composite components, have become indispensable in the aerospace industry today. But also in the automotive sector, the use of such materials is becoming more and more popular.
  • critical structural elements are made of fiber reinforced plastics due to the high weight specific strength and stiffness with minimal weight. Due to the anisotropic properties of the fiber composite materials resulting from the fiber orientation, components can be adapted exactly to local loads and thus enable optimal material utilization in terms of lightweight construction.
  • prepregs sin-finished fiber products preimpregnated with a matrix material
  • the fibrous materials can be dry, ligated, pre-fixed or preimpregnated fabrics, nonwovens, uniaxial or multiaxial Be materials.
  • Multiaxialgelege which are composed of two or more fiber layers, either manufactured with a constant width and basis weight per meter or individually using a Tapelegers or a robot laying device.
  • the object is achieved by the method according to claim 1 and the system according to claim 10 according to the invention.
  • the invention proposes that initially a pattern by dividing the fiber preform geometry into a plurality of sub-elements which, when assembled, are to form the later fiber preform geometry with the predetermined outer end contour. Subsequently, the sub-elements are arranged to form a pattern with which the individual sub-elements are to be cut from a fiber material.
  • the generation of the pattern is carried out in dependence on the outer contour of the individual sub-elements, which are to form the geometry of the later fiber preform.
  • the determination of the geometry and arrangement of the individual sub-elements is carried out with the aid of running on a calculating machine optimization method, taking into account the outer contour of the individual sub-elements in order to minimize the waste between adjacent sub-elements of the pattern.
  • the subdivision of the fiber preform geometry in the individual sub-elements and the generation of the pattern can be done using a microprocessor-controlled pattern determination unit.
  • the outer contour of the determined sub-elements corresponds to the outer end contour of the fiber preform.
  • the fiber preform is produced from the individual partial elements by cutting the individual partial elements from the fibrous material according to the pattern by placing or depositing the partial elements before, during or after cutting to form the fiber preform.
  • the fiber preform is thus formed with its predetermined geometry and outer end contour.
  • a fiber preform is a semifinished fiber product formed from a fiber material which at least partially contains the later component form of the fiber composite component to be produced.
  • the optimization method in the sense of the present invention is the solution of an optimization problem such that a desired parameter of the task is minimized with the aid of an objective function.
  • the parameter to be minimized here is the blend, by which the excess material of adjacent sub-elements in the pattern is understood.
  • the target function can be designed in such a way that it minimizes the parameter blending with the aid of an analytical or a numerical method.
  • the steps of subdividing the geometry and generating the pattern are performed multiple times, each time generating different geometries of the individual subelements in the subdivision of the fiber preform geometry.
  • This is particularly advantageous if the application of the method is not restricted to a predefined material size, for example material width.
  • the patterns produced at each pass are then compared with respect to their respective blends, so that, for example, that particular cutting pattern is used that has the least scrap.
  • the cutting pattern of the sub-elements is further generated as a function of a predetermined fiber angle orientation, a permissible cutting angle of the fiber material and a minimum size of a sub-element.
  • the cutting pattern is produced as a function of a number of layers of the fiber preform to be built up.
  • These boundary conditions can have a significant influence on how the sub-elements are arranged within the pattern, for example, as a rule, the fiber preform must have a predetermined fiber angle orientation and thus the sub-elements can not be cut out arbitrarily from the fiber material. Rather, the sub-elements, depending on the position and arrangement within the fiber preform, must correspond to the predetermined fiber angle orientation.
  • a permissible cutting angle of the fiber material and the number of layers to be built up of the fiber preform have a relevance with regard to the arrangement of the sub-elements in the cutting pattern with respect to the fiber material.
  • the fiber preform may, for example, be produced in such a way by initially depositing fiber material of a partial element at least partially. Before it is finally deposited, it is cut according to the pattern at its last cut edge. This is particularly advantageous when the sub-elements are deposited from a fiber endless material, so that the process step of cutting and depositing coincides.
  • the sub-elements inevitably have to be stored next to each other, but in terms of their position within the fiber preform according to pattern.
  • the sub-elements are cut from the fiber material according to the pattern and then the cut sub-elements are stored for the production of the fiber preform. It is advantageous if the cut sub-elements are sorted prior to depositing with respect to their position within the fiber preform and stored sorted in a material storage.
  • the deposition order for the cutting of the sub-elements is relevant, but the order of the cut elements primarily result from the minimization of the waste, it is particularly advantageous the cut sub-elements are sorted prior to depositing with respect to their position within the fiber preform, so that during the deposition process by means of the fiber laying unit, the individual sub-elements can be successively removed from the material storage and stored. As a result, the productivity of the laying process can be increased despite the increased cost when cutting the partial elements.
  • the fiber preform geometry is subdivided into a plurality of strip-shaped sub-elements having a predetermined strip width and the individual strip-shaped sub-elements as Fiber strips cut one after another from a Faserendlosmaterial.
  • This is desirable, for example, when the laying process for the production of the fiber preform is based on the fact that individual fiber strips are to be laid from a continuous fiber material with a predetermined material width.
  • the pattern is thereby produced by arranging the individual fiber strips one after the other on the fiber endless material, the sequence of the fiber strips on the fiber endless material being determined by means of the optimization method for waste optimization as a function of the outer contours of the fiber strips.
  • the individual fiber strips are arranged with respect to their order so that, for example, identical or similar outer contours, which correspond to a cut edge in the cutting of the fiber strips of the continuous material, are arranged adjacent, whereby the waste is minimized when cutting the fiber strips.
  • the cutting edge between two adjacent fiber strips each form the contiguous outer contours of the fiber strips.
  • the outer contours would be identical in terms of their cutting process.
  • the fiber strips on the continuous filament material to be arranged with respect to their sequence in such a way that those fiber strips are arranged adjacent whose outer contours are congruent within a predetermined tolerance range. This also minimizes waste.
  • the course of the cutting edge between subelements adjacent to each other in the cutting pattern can be optimized by means of the optimization method, for example by selecting cutting profiles which lead to a minimal scrap, even if the desired outer contour of the subelement is not realized by the cutting edge can be and this can lead to a final contour trimming. While this is at the expense of productivity, it does increase it at the same time significant savings in wastage.
  • all partial elements or at least one part have a cutting edge which corresponds to the outer contour of the fiber preform.
  • targeted partial elements can be produced with a finished outer contour, which can increase productivity, as a subsequent contouring is eliminated.
  • firstly all partial elements or at least a part thereof are cut according to the generated pattern and the cut partial elements are temporarily stored in a material storage prior to deposition, so that the entire deposition process can be carried out without the process step of cutting.
  • the individual sub-elements are additionally stored temporarily in the material store before they are deposited.
  • the number of sub-elements in the cutting pattern is minimized by means of the optimization method running on the calculating machine.
  • the productivity can be significantly increased since, with fewer sub-elements, the process step of depositing the individual sub-elements is reduced / shortened.
  • the optimization method can be so with the specifications of a minimum number of sub-elements and a minimum In terms of productivity, it is important to achieve a balance between the waste that needs to be reduced and the amount of waste that needs to be reduced. By appropriate specifications, such as increasing productivity or reducing waste, an optimum can be found here with respect to these specifications.
  • the sub-elements consist of unidirectional, mutually parallel and just prepared continuous fibers.
  • the sub-elements consist for example of fabric, fleece or multiaxial material.
  • the sub-elements may consist of dry, prebent, pre-fixed or already preimpregnated fiber material.
  • certain sub-elements may also consist of other auxiliary materials, for example binder fleece, visible fabric or special foils.
  • a sub-element advantageously always has two mutually parallel sides. The mutually parallel sides then advantageously run parallel along an existing fiber angle orientation.
  • a partial element can also have any outer contour that corresponds to the outer contour of the fiber preform at the position of the partial element.
  • the sub-elements advantageously have uniform widths. So it is advantageously only one or two give different widths of subelements. However, it is also conceivable that significantly more different widths are available or completely dispensed with uniform widths.
  • FIG. 1 shows in three variants A to C the respective material consumption.
  • a fiber preform 100 is to be produced by means of fiber strips 110, 112, 114 and 116, wherein the respective fiber strips are to be cut out of a continuous fiber material and thus have a predetermined solid material width.
  • the fiber preform 100 has a circular geometry and outer end contour.
  • the fiber strips are successively cut off from a continuous filament ribbon of material by means of a substantially rectangular angle of intersection.
  • this variant has the largest waste, since the difference to the outer end contour of the fiber preform 100 is greatest due to the rectangular geometry of the individual fiber strips.
  • the order of the arrangement and the cutting angle is optimized, so that the waste is minimized.
  • the cutting angles are generated in such a way that the cutting edge resulting from the cutting angle corresponds in each case to two successive fiber strips.
  • variant B is the FIG. 1 shown that the fiber strips 110 and 116 on have at least one side an identical cutting angle, so that these fiber strips 110 and 116 can be arranged on the FaserstMailendlosmaterial successively and have a common cutting edge. As a result, the material consumption compared to the first variant A can be reduced.
  • variant C of FIG. 1 has been chosen a different arrangement of the fiber strips, which now give common cut edges of the fiber strips 110 and 112 and the fiber strips 114 and 116 and beyond the fiber strips 112 and 116 may also have a common cutting edge. According to this arrangement, the material consumption and thus the waste can be reduced again compared to the variant B.
  • the central fiber strips 112 and 114 are first arranged on the fiber strip endless material, whereupon the outer left fiber strip 110 and then the outer right fiber strip 116 follow. It can also be seen that the fiber strip 110 has no bevelled cutting angle on its lower side, so that it can be cut off with the cutting edge 114 previously arranged on the fiber strip endless material with a cut edge.
  • the two inner fiber strips are arranged on the fiber strand endless material outside, while the two outer fiber strips are then arranged centrally thereof.
  • the fiber strips can thus each be different be arranged on the FaserstMailentlosmaterial, in which case a respective intersection angle between the two fiber strips is determined, which generates a minimum waste.
  • the generation of the cutting pattern with the aid of the optimization method can thus take place in two stages, on the one hand by an optimal arrangement of the individual fiber strips with respect to their required outer contour to form the outer end contour of the fiber preform 100, and on the other hand by the determination of an optimum cutting edge, so that in the sum of the waste is minimized.
  • FIGS. 2a and 2b show two different variants, as two fiber strips can be arranged with their required outer contour, so that there is an optimal angle of intersection.
  • FIG. 2a This is the safest and simplest variant, since the cutting angles of the two fiber strips 210 and 220 do not intersect within the material region. It is irrelevant whether at the cutting edge 212 or 222, the two fiber strips are separated from each other, since in both cases a final contour trimming is necessary and the waste remains the same.
  • both cut angles would intersect within the material area because the two fiber strips 210 and 220 are placed directly adjacent one another.
  • the cutting edge for cutting off the two fiber strips would then take place at the cutting edge 222, wherein the waste when cutting the outer contour for the fiber strip 210 with respect to the variant of FIG. 2a is lower.
  • FIG. 3 shows an embodiment in which the fiber preform is not generated from a plurality of fiber strips with the same fiber strip width, but by individually tuned sub-elements.
  • the fiber preform 300 with its desired geometry and final contour is in subdivided a plurality of sub-elements 310, 312, 314, 316, 318 and 320, wherein these individual sub-elements are then arranged on a fiber material 330 correspondingly so that the waste is minimized.
  • a cutting pattern is produced, which has optimally matched cutting contours in the base material in order to reduce the waste while at the same time increasing productivity, since fewer strips have to be deposited and thus less transport effort or less necessary movement of the robotics when depositing the fiber strips lead to a significant reduction in production time.
