Description

[0001] The present invention relates to an improved production of a fiber composite component complex. In particular, the present invention relates to a winding core for receiving fibers for the production of a fiber composite component having a connection section, a production method for producing a fiber composite component with a connection section for connecting a connection component to the fiber composite component, a production method for producing a fiber composite component complex from at least one first fiber composite component and at least one connection component, and a fiber composite component complex comprising a fiber composite component and a connection component.

[0002] In automobile manufacturing, reducing the overall weight of the vehicle is of increasing importance, as a lower weight is linked to improved driving dynamics, reduced fuel consumption, and lower emissions. This relationship is based on the physical law of inertia, according to which accelerating a mass to a given acceleration requires a force proportional to that mass. Therefore, reducing the mass of a vehicle, such as an automobile, means that less driving force is required to achieve a given acceleration.

[0003] To reduce vehicle weight, it is common practice to replace sheet steel components, such as pipes, beams, body panels, and the like, with fiber-reinforced composite components, such as fiber-reinforced plastic (FRP) components. Compared to sheet metal components, fiber-reinforced composite components exhibit a particularly low specific weight combined with exceptionally high stiffness. Fiber-reinforced composite components consist of a fiber component that is permeated or impregnated with a matrix material, such as a resin. Fiber-reinforced composite components can be manufactured, for example, using a resin injection molding process, also known as injection molding or resin transfer molding (RTM), or a wet pressing process.

[0004] In injection molding, a preform made of fiber material is placed in an injection mold and, with the mold closed, impregnated or permeated with the matrix material. In wet molding, the preform is first impregnated or permeated with the matrix material, for example in an immersion bath, and then compacted in a wet mold. In both processes, the preform can be produced, for example, by a winding process in which the fiber material is wound around a core.

[0005] To join at least two fiber composite components to form a fiber composite component complex, for example in a T-joint or I-joint, additional joining devices are required to ensure sufficient stability at the connection point. In a T-joint, an end face of a first fiber composite component is positioned against a longitudinal side of a second fiber composite component. A T-shaped sleeve is positioned laterally at the connection point and bonded to both fiber composite components. An additional sleeve may be provided, which is bonded to the connection point from the opposite side. In an I-joint of two tubular fiber composite components, the fiber composite components are joined at their end faces.For this purpose, a pipe with an inner diameter corresponding to the outer diameters of the fiber composite components to be joined is used as a connecting device and bonded to them. For both T-joints and I-joints, fiber material can be used as an alternative connecting device; this material is, for example, wound onto an area of ​​the connection point and impregnated with a matrix material.

[0006] Known methods for joining fiber-reinforced composite components have the disadvantage that additional joining devices are required to connect the components. These devices must be manufactured, stored, prepared, and assembled in separate production processes. This results in high manufacturing, storage, and assembly costs. Furthermore, different connection points require special joining devices, particularly sleeves or tubes, which vary in shape and size. This can lead to a high degree of part diversity and a corresponding risk of confusing joining devices. Additionally, bonding the joining device by adhesive often represents a structural weak point that, under high load, can lead to failure of the fiber-reinforced composite component complex at the connection point, particularly to sleeve tearing.Finally, sleeves designed to ensure sufficient stability of the fiber composite component complex require a significant amount of additional material and cause excessive local expansion of the fiber composite component complex in the area of ​​the connection point.

[0007] It is therefore an object of the present invention to eliminate, or at least partially eliminate, the disadvantages described above in a fiber composite component complex or in the production of a fiber composite component complex. In particular, it is an object of the present invention to provide a winding core for receiving fibers for the production of a fiber composite component having a connection section, a manufacturing method for producing a fiber composite component with a connection section, a production method for producing a fiber composite component complex from at least one first fiber composite component and at least one connection component, and a fiber composite component complex that enable or feature an improved, in particular space-saving, material-saving, secure and / or easily manufacturable, connection of a fiber composite component with a connection component in a simple and cost-effective manner.

[0008] The aforementioned problem is solved by the patent claims. Accordingly, the problem is solved by a winding core for receiving fibers for the production of a fiber composite component having a connection section, comprising the features of claim 1; a manufacturing method for producing a fiber composite component with a connection section for connecting a connection component to the fiber composite component, comprising the features of claim 6; a production method for producing a fiber composite component complex comprising at least one first fiber composite component and at least one connection component, comprising the features of claim 13; and a fiber composite component complex comprising at least one fiber composite component and at least one connection component connected to the fiber composite component, comprising the features of claim 15. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings.Features and details described in connection with the winding core according to the invention naturally also apply in connection with the manufacturing process, the production process, and the fiber composite component complex according to the invention, and vice versa, so that the disclosure regarding the individual aspects of the invention always refers to each other or can refer to each other.

[0009] According to the first aspect of the invention, the problem is solved by a winding core for receiving fibers for the production of a fiber composite component having a connection section. The winding core has a core body for receiving fibers to create a component body of the fiber composite component. According to the invention, the winding core has an additional core body for receiving fibers to create the connection section of the fiber composite component, wherein the additional core body is connected to the core body via a coupling section such that, after the fibers have been arranged on the winding core, the additional core body can be separated from the core body at the coupling section.

[0010] The winding core is designed for shaping fibers, such as carbon fibers, aramid fibers, glass fibers, or the like. The fibers can be arranged on the winding core by winding or braiding. The winding core thus defines a fiber-free space or a cavity surrounded by fibers. According to the invention, the winding core has two sections: a core body and at least one core extension body, which is connected to the core body via a coupling interface, for example, formed integrally with it, glued to it, hooked onto the core body, screwed on, or similarly. Thus, the core extension body can be easily separated from the core body at the coupling interface.

[0011] The core body corresponds to a winding core for the production of a conventional fiber composite component that has no connection section. Preferably, the core body is designed such that it can be easily removed from the finished fiber composite component without damaging the component. It is therefore preferred that the core body has a shape that allows it to be pulled out of the fiber composite component. Alternatively or additionally, the core body can be designed to be easily destroyed, so that it can be removed from the fiber composite component by breaking it. The core body is preferably designed as a foam or as a water-filled body.

[0012] The core component is designed for the production of a connection section of the fiber composite component. At least one fiber arrangement can be achieved using the core component, from which the connection section can be formed, for example, using a preforming tool in a preforming process. Fibers can be arranged on the core component for this purpose, for example, by winding or braiding them around it. A connection section is a section designed for attaching a connecting component, such as another fiber composite component. The connection section has a contact surface for the attachment of the connecting component.Preferably, the connection section is designed to hold the connection component positively in several directions relative to the fiber composite component, preferably such that the connection component can be arranged on the connection section in only one joining direction and removed from the connection section in a separation direction opposite to the joining direction. The connection section thus replaces a conventional connecting device, such as a sleeve, a retaining plate, or the like.

[0013] Furthermore, the core additive body is designed to be removable from the core base body and from the arranged fibers. For this purpose, the core additive body has, for example, a shape that facilitates or at least does not hinder the removal of the wrapped core additive body from the fibers, e.g., by means of undercuts. Alternatively or additionally, the core additive body can be designed to be easily destroyed, so that it can be removed from the fibers by breaking it. According to the invention, an easily destroyed core additive body also includes a core additive body that can be melted and / or vaporized or diffused by thermal action, in particular by the application of heat. Preferably, within the scope of the invention, an easily destroyed core additive body means that the core additive body is more easily destroyed than the core base body.

[0014] The core additive body is preferably designed as a foam, water-filled body or simple plastic part.

[0015] Using such a winding core, fiber composite components can be manufactured simply and cost-effectively. These components feature a connection section for attaching other components, such as another fiber composite part. This eliminates the need for additional connecting devices to create a fiber composite component complex, thus saving production steps. Furthermore, the connection section reduces material usage, as less material is required to manufacture the connection section than a separate connecting device. This further reduces costs. Moreover, the integrated design of the connection section and the fiber composite component improves the overall strength of the fiber composite component complex.Furthermore, the fiber composite component complexes that can be produced in this way have smaller external dimensions at the connection section than conventional fiber composite component complexes with additional connecting devices.

[0016] According to a preferred embodiment of the invention, a winding core can be provided with a core extension body that has an end section facing the core body and at least one intermediate section facing away from the core body, wherein the intermediate section has a greater extent in at least one direction transverse to a longitudinal direction of the core extension body than the extent of the end section. According to the invention, a longitudinal extent of the core extension body is understood to be, in particular, a direction pointing away from the core body. A direction transverse to the longitudinal extent preferably runs parallel or substantially parallel to a longitudinal direction of the core body. Particularly preferably, the core extension body has a graduated change in extent from the end section to the intermediate section. This facilitates the removal of the core extension body from the fibers.

[0017] Preferably, the core addition body has a core addition body thickness that is less than the core base body thickness. The core base body is therefore preferably used to produce a hollow component, and the core addition body is used to produce a wall that can be deformed by preforming to form the connection section.

[0018] According to the invention, it is preferred that the coupling section is designed as a predetermined breaking point. Such a predetermined breaking point preferably has a geometric design with increased notch effect, such as at least one acute angle or at least one notch with an acute angle. Alternatively or additionally, the predetermined breaking point can have a reduced cross-sectional area. The predetermined breaking point can also alternatively or additionally have a different chemical composition than the core body or the core accessory body, such as a relatively weak adhesive arranged between the core body and the core accessory body. A weak adhesive is, for example, an adhesive that forms a bond that can be easily released, such as manually, preferably without additional tools, by heating, or by vibration.Predetermined breaking points have the advantage of facilitating the separation of the core extension body from the core base body. This reduces the risk of damage to the fiber assembly resulting from the separation of the core extension body from the core base body.

[0019] According to the invention, the core additive body can be arranged on an end face or on a flank region of the core base body. In this way, differently configured connections between fiber composite components can be achieved. An arrangement of the core additive body on an end face of the core base body is particularly preferred, as this allows for a good connection of a flank region of a connecting component.

[0020] According to a second aspect of the invention, the problem is solved by a manufacturing process for producing a fiber composite component with a connection section for connecting a connecting component to the fiber composite component. The manufacturing process comprises the following steps: – Providing a winding core according to the invention, – Creating a fiber arrangement by arranging fibers on the winding core, wherein a basic fiber arrangement is created on the core body and an additional fiber arrangement is created on the core supplementary body, – Removal of the core add-on body of the winding core from the add-on fiber arrangement, – Preforming the additional fiber arrangement using a molding tool, – Impregnating the fiber arrangement with a matrix material, and – Curing of the matrix material to produce the fiber composite component.

[0021] The winding core according to the invention is preferably provided on a fiber arrangement device for arranging fibers on the winding core, such as a winding device or a braiding device. Subsequently, a fiber arrangement is created on the core body and the core extension body by adding fibers, in particular continuous fibers, using the fiber arrangement device. The fiber arrangement arranged on the core body is referred to as the base fiber arrangement, and the fiber arrangement arranged on the core extension body is referred to as the extension fiber arrangement. The fiber arrangement can be created, for example, by braiding, winding, or the like.

[0022] The core additive body is then separated from the base body. This preferably occurs when the additive fiber arrangement is completed or substantially completed. The core additive body is then removed from the additive fiber arrangement. According to the invention, this removal can also take place during preforming. For the purposes of the invention, a core additive body that is deformed during preforming and thus becomes part of the connection section is also considered removed.

[0023] In a subsequent process step, the connection section is produced from the additional fiber arrangement by preforming using a preforming tool. The fibers of the additional fiber arrangement are preferably compressed and shaped into the form of the connection section. The connection section preferably has a concave or substantially concave shape to securely receive the connection component. This ensures that detachment of the connection component from the connection section is positively limited in at least several directions. Preferably, the preforming is carried out substantially locally with the additional fiber arrangement.

[0024] It may be provided that during preforming, a sub-area of ​​the base fiber arrangement, which is adjacent to the additional fiber arrangement, is also preformed.

[0025] The fiber arrangement, i.e., the base fiber arrangement and the preformed additional fiber arrangement, is subsequently impregnated with a matrix material, such as a thermosetting matrix material, in particular a resin, or a thermoplastic matrix material. This is preferably carried out in an injection mold. It can also be provided that the impregnation takes place before or during preforming. After the matrix material has cured, a fiber composite component with a connection section is complete. According to the invention, further processing steps, such as removing the core body from the fiber composite component, pressing the component body or the component body and the connection section before and / or during and / or after impregnation, trimming protruding fibers, deburring, or the like, can be provided within the scope of the manufacturing process according to the invention to improve the fiber composite component.Preferably, the fiber composite component is finished using an injection molding process.

[0026] The described manufacturing process offers all the advantages already described for a winding core for receiving fibers for the production of a fiber composite component with a connection section, according to the first aspect of the invention. Consequently, fiber composite components with a connection section for attaching a connecting component, such as another fiber composite component, can be produced simply and cost-effectively using this manufacturing process according to the invention. Therefore, the use of additional connecting devices is no longer necessary for producing a fiber composite component complex. This eliminates the need for several work steps in the production of the fiber composite component complex.Furthermore, the connection section reduces the amount of material required to produce the fiber composite component complex, as less material is needed to manufacture the connection section than to produce a separate connecting device. This allows for further cost reductions. Moreover, the one-piece design of the connection section and the fiber composite component improves the strength of the fiber composite component complex. Additionally, the resulting fiber composite component complexes have smaller external dimensions at the connection section than conventional fiber composite component complexes with additional connecting devices.

[0027] Preferably, the fiber arrangement is produced by braiding. This is preferably done on a braiding device specifically designed for this purpose. Braiding creates a mesh in which the fibers are interwoven. Such meshes can, for example, exhibit particularly advantageous isotropic and / or anisotropic mechanical properties. This makes it possible to produce fiber composite components that are optimally designed for specific load conditions. Furthermore, braiding can produce a fiber arrangement that exhibits high inherent stability and high mechanical strength and is particularly suitable for further processing into a fiber composite component.

[0028] According to the invention, it is preferred that the base fiber arrangement and the additional fiber arrangement are produced as a continuous fiber arrangement. Within the scope of the invention, a continuous fiber arrangement is understood to be a fiber arrangement in which at least some of the fibers belong to both the base fiber arrangement and the additional fiber arrangement. These fibers thus extend partially over the base fiber arrangement and partially over the additional fiber arrangement. Preferably, the fiber arrangement is designed such that no separation joints are formed between the base fiber arrangement and the additional fiber arrangement. This improves the cohesion of the base fiber arrangement and the additional fiber arrangement.

[0029] In an advantageous embodiment of the manufacturing process according to the invention, a binder is applied to at least the additive fiber arrangement before preforming. The binder is designed to bind the fibers of the additive fiber arrangement together, resulting in increased dimensional stability compared to fibers without a binder. According to the invention, the binder is applied at least before the preforming process is complete. It is also possible, according to the invention, for the core additive body to already contain the binder before the fiber arrangement is formed, or to be designed as a binder. More preferably, the preforming is carried out such that the binder hardens, or at least partially hardens, during preforming. This ensures, simply and cost-effectively, that the additive fiber arrangement does not relax after preforming and thus prevents deformation of the bonding section.

[0030] Preferably, a thermoplastic adhesive is used as the binder. A thermoplastic adhesive has the advantage that it can be softened or liquefied by heating and hardened or solidified by cooling. Preforming under heat is easily possible using such a thermoplastic adhesive. Furthermore, dimensional stability of the preformed connection section can be achieved by cooling it.

[0031] According to a preferred embodiment of the process, heat is introduced into the additive fiber arrangement during preforming. This is particularly advantageous when using a thermoplastic binder, as the viscosity of the binder can be reduced by heating.

[0032] According to the invention, it is preferably provided that preforming and impregnation are carried out in the same mold, such as an injection mold. Preferably, the mold is not opened between preforming and impregnation. Such a mold has the advantage that fewer work steps are required to carry out the process. Removing the fiber assembly from a preforming mold after preforming and inserting the fiber assembly into an injection mold are eliminated. This allows the manufacturing costs of fiber composite components to be reduced using simple means.

[0033] According to a third aspect of the invention, the problem is solved by a manufacturing process for producing a fiber composite component complex consisting of at least one first fiber composite component and at least one connecting component. The manufacturing process comprises the following steps: – Manufacturing at least one first fiber composite component having a connection section by means of a manufacturing process according to the invention, and – Arranging and fixing the connecting component to the connection section of the first fiber composite component. First, a first fiber composite component is manufactured using a manufacturing process according to the invention. Then, the connecting component is arranged and fixed to the connection section of the first fiber composite component. By arranging the connecting component, it is positively locked to the first fiber composite component in at least several directions. Fixing is achieved in particular by bonding with an adhesive and / or by clamping, for example, using a clamp or the like.

[0034] The described manufacturing process offers all the advantages already described for a winding core for receiving fibers for the production of a fiber composite component with a connection section according to the first aspect of the invention, as well as for a manufacturing process for producing a fiber composite component with a connection section according to the second aspect of the invention. Consequently, fiber composite component complexes can be produced simply and cost-effectively using the manufacturing process according to the invention, in which at least one fiber composite component is connected via a connection section to a connecting component, such as another fiber composite component. The use of additional connecting devices is not required for the production of the fiber composite component complex. Thus, several work steps in the production of the fiber composite component complex can be saved.Furthermore, the connection section reduces the amount of material required to produce the fiber composite component complex, as less material is needed to manufacture the connection section than to produce a separate connecting device. This allows for further cost reductions. Moreover, the one-piece design of the connection section and the fiber composite component improves the strength of the fiber composite component complex. Additionally, the resulting fiber composite component complexes have smaller external dimensions at the connection section than conventional fiber composite component complexes with additional connecting devices.

[0035] It is preferred that the connecting component is designed as a second fiber composite component. The second fiber composite component may have a connecting section for attaching a further connecting component. According to the invention, it may be provided that the second fiber composite component does not have a connecting section. The fiber composite component complex preferably comprises a plurality of second fiber composite components, which are connected to the first fiber composite components via such connecting sections, each of which is formed integrally with a first fiber composite component.

[0036] According to a fourth aspect of the invention, the problem is solved by a fiber composite component complex. The fiber composite component complex comprises a first fiber composite component with a base body and a connection section, and a connection component that is attached to the connection section. The fiber composite component complex is manufactured using a production method according to the invention. The connection section is thus integrally formed with the base body.

[0037] The described fiber composite component complex offers all the advantages already described for a winding core for receiving fibers for the production of a fiber composite component with a connection section according to the first aspect of the invention, for a manufacturing method for producing a fiber composite component with a connection section according to the second aspect of the invention, and for a production method for producing a fiber composite component complex according to the third aspect of the invention. Consequently, the fiber composite component complex according to the invention can be manufactured simply and cost-effectively. Furthermore, the fiber composite component complex exhibits high stability because at least one fiber composite component is connected via a connection section to a connecting component, such as another fiber composite component. The fiber composite component complex requires no additional connecting devices.This allows for the elimination of work steps in the production of the fiber composite component complex. Furthermore, the connection section reduces material usage for the production of the fiber composite component complex, as less material is required for its manufacture than for a connecting device. This further reduces costs. Moreover, the one-piece design of the connection section with the fiber composite component improves the strength of the fiber composite component complex. Finally, the fiber composite component complex according to the invention has smaller external dimensions at the connection section than a conventional fiber composite component complex with an additional connecting device.
