Definitions

  • the invention relates to a device and a method for producing a molded body from a fiber material.
  • Carbon fibers are increasingly in demand as substitute materials for traditional materials due to their mechanical and functional properties.
  • Carbon fiber reinforced structural components have a very high strength and at the same time are low in weight.
  • high demands are placed on the quality and processing characteristics of the components to be manufactured from the carbon fibers.
  • a semi-finished fiber product provided with a binder material is first formed into a preform in a preform tool;
  • the binder material is activated by the action of heat in the preform tool and the three-dimensional shape of the preform is fixed in this way.
  • the fiber orientation of the fiber preform is determined.
  • the preform is then infiltrated with a resin using an infusion process (for example resin transfer molding (RTM) or vacuum assisted resin infusion (VARI)), which is then cured by the action of heat.
  • RTM resin transfer molding
  • VARI vacuum assisted resin infusion
  • the semi-finished fiber product or the fiber preform is usually heated by means of a heating device that is integrated in the preform tool or in the infusion tool.
  • fiber material should be understood to mean any desired textile starting material, the fibers of which are provided with a hardenable binder material. From this fiber material, a sheet-like textile structure, in particular a special fabric, knitted fabric, braid, etc. is made and brought into a three-dimensional shape. This three-dimensional shape is then made by a Fixed hardening process in which the binder material is activated. This hardening is conventionally carried out in a molding tool.
  • the textile structure, which forms the starting material for the production of the preform is typically produced by a weaving process. Such a textile structure is present in particular as a flat fiber mat, which is cut into the desired shape in the preform tool prior to reshaping.
  • the object of the present invention is to propose a method for producing a molded body from a fiber material, with the aid of which the above-mentioned problems can be circumvented. Furthermore, it is the object of the invention to create a device with the help of which such molded fiber bodies can be produced.
  • the method according to the invention provides that a textile structure is first produced from the fiber material by means of textile technology in a manufacturing unit.
  • the textile structure is provided with a binder material, the binder material either being applied to the fiber material before the textile processing or to the fiber material during or after the textile processing
  • Fiber material is applied.
  • the textile structure is then formed three-dimensionally in a predetermined manner in a deformation step, and the deformation of the textile structure produced thereby is fixed by activating the binder material.
  • the binder material is activated iteratively.
  • An “iterative" activation should be understood to mean that the binder material is activated step by step in some selected areas of the textile structure (and the shape of the structure is thereby fixed in these areas) before activation / fixation in other areas of the textile structure he follows.
  • the fixing in the method according to the invention thus takes place in regions or sections.
  • a selected area of the textile structure is first brought into the desired shape by reshaping and then fixed by activating the binder material.
  • adjacent areas can be shaped and fixed in such a sequence that wrinkling of the fiber mats is effectively prevented.
  • the basic idea of the method according to the invention is to cure the textile structure step by step and locally immediately after its production and to position the already cured areas during the curing process in such a way that the part of the textile to be cured len structure is in the correct / desired position / orientation.
  • the hardened areas stabilize the three-dimensional shape of the finished areas and support the forming process.
  • the iterative activation of the binder material takes place during the process, i.e. with a temporal overlap with the technical textile production of the textile structure, so that the textile structure emerging from the finishing unit is reshaped and fixed in certain areas, while other areas of the structure are still in the production process in the finishing unit .
  • the fixing unit can influence the finishing unit by setting the textile tension higher or lower in certain areas; In this way, for example, wrinkling and / or internal stresses in the textile structure can be prevented or at least reduced. This textile tension can also be reduced for positioning / aligning the textile structure, so that it is possible to “rotate” the structure.
  • the reshaping of the textile structure also advantageously takes place in a temporal overlap with the fixing of the binder material.
  • the textile structure is brought into the desired three-dimensional shape locally, for example, and locally hardened by activating the binder material contained in the textile structure.
  • the area hardened in this way is thus fixed in the desired shape and thus forms a support for other areas that are to be reshaped and fixed.
  • the reshaping of the textile structure is preferably carried out with the help of Manipulato Ren, which can be designed as a movable stamp, gripper, etc.
  • Manipulators can be positioned and operated in particular with the help of industrial robots.
  • tools can be used that consist of a large number of movable pressure stamps, hold-down devices, etc.
  • the textile structure can be reshaped in a variety of ways in order to automatically produce molded fiber bodies with a wide variety of geometries.
  • the programming of the manipulators can be modified quickly in order to achieve changes in the geometry of the shaped bodies to be produced. The programming could also take place during the entire process - modifications or programming could therefore be carried out as long as the molded fiber body has not yet reached the area to be changed.
  • the programming / modification could take place between the production of individual molded fiber bodies.
  • the textile structure can in particular be a fabric that has been produced using a web process.
  • Fabrics are flat structures that consist of two Fadensyste men, warp threads and weft threads that cross each other in a pattern. The warp threads run in the longitudinal direction of the fabric, parallel to the fabric edge, and the weft threads in the transverse direction, parallel to the fabric edge.
  • weaving processes are also known from the prior art, with the help of which fiber structures of different thicknesses can be woven.
  • complex multi-layer weaving methods with layer-to-layer interlocking and methods for weaving in three dimensions are known. By using a suitable weaving technique, a wide range of textile structures can be produced.
  • the textile structure woven in this way can then, for example, be locally hardened in areas or immediately after each weaving step, and during the hardening process the already woven and hardened area can be positioned in such a way that the area to be newly hardened is in the correct position / Alignment is.
  • the invention thus enables the production of complex woven and three-dimensional structures from a fiber material.
  • the binder material can be activated in particular by electromagnetic radiation, in particular by infrared radiation.
  • the area of the textile structure to be fixed is heated with the aid of an infrared source.
  • the binder material is a thermoplastic material, in particular a thermoplastic powder, it is melted by the heat, solidifies when it cools and fixes the local shape of the textile structure.
  • the binder material is a thermoset, the action of heat triggers a crosslinking reaction that fixes the shape.
  • the textile structure contains electrically conductive fibers (e.g. carbon fibers)
  • the binder material can also be activated by an electric current. Selected electrically conductive fibers of the textile structure are connected to a power source. In the area of the crossing points of the energized fibers, heating takes place. The current strength is chosen so that the temperature in the area of the crossing points is so high that the binder material melts or is crosslinked and fixes the three-dimensional shape of the textile structure there.
  • the binder material can also be activated chemically, in particular by applying a correspondingly effective substance, for example in the form of a hardener.
  • a device for producing a molded body comprises a finishing unit with a textile-technical system in which a textile structure is produced from a fiber material.
  • the textile-technical system can in particular be a loom, for example a single-phase loom.
  • the device comprises a fixing unit for iterative spatial fixing of the textile structure emerging from the textile-technical system.
  • the fixing unit advantageously contains a shaping unit with the aid of which the textile structure emerging from the technical textile system can be spatially shaped in a predetermined manner before the shape created in this way is permanently fixed.
  • This forming unit can comprise a large number of controlled and / or regulated moveable and activatable manipulators, in particular grippers, tongs, stamps, etc., which act on the textile structure emerging from the textile-technical system.
  • manipulators in particular grippers, tongs, stamps, etc.
  • the manipulators can be guided and operated with the aid of industrial robots. Direct use of a robot as a manipulator is also conceivable.
