Description

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 connection portion having fiber composite component, a manufacturing method for producing a fiber composite component with a connection portion for connecting a connection component to the fiber composite component, a production method for producing a fiber composite component complex of at least one first fiber composite component and at least a connection component and a fiber composite component complex comprising a fiber composite component and a connection component.

In the manufacture of automobiles, a reduction in the overall weight of the automobile is of increasing importance, as a reduced total weight is associated with an improvement in driving dynamics, a reduction in fuel consumption, and a reduction in emissions. This relationship is based on the physical law of inertia, which requires a force proportional to mass to accelerate a mass at a given acceleration. A reduction in the mass of a vehicle, such as e.g. of an automobile thus means less required driving force to achieve a given acceleration.

To reduce the vehicle weight, it is known to use sheet steel components, e.g. Tubes, beams, body panels or the like, by fiber composite components, e.g. Fiber-plastic composite components (FRP components) to replace. Fiber composite components have a particularly low specific weight compared to sheet metal components with a particularly high rigidity. Fiber composite components comprise a fiber component derived from a matrix material, such as e.g. a resin, interspersed or impregnated. The production of fiber composite components, for example, by means of a resin injection process, which is also referred to as transfer molding or "Resin Transfer Molding (RTM)" or a wet pressing process.

In transfer molding, a preform made of fiber material is introduced into a transfer molding tool and impregnated or penetrated with the matrix material when the transfer molding tool is closed. In wet pressing, the preform is first impregnated with the matrix material, e.g. in a dip bath, and then compressed in a wet pressing tool. In both methods, the preform can be done, for example, by a winding process in which the fiber material is wound around a winding core.

For connecting at least two fiber composite components to a fiber composite component complex, for example in the T-joint or I-joint, additional connection devices are required in order to ensure sufficient stability of the connection point of the fiber composite components. In a T-joint, an end face of a first fiber composite component is arranged on a longitudinal side of a second fiber composite component. A T-shaped cuff is arranged laterally at the connection point and glued to the two fiber composite components. In addition, a further sleeve may be provided, which is glued from an opposite side to the connection point. In an I-shock of two tubular fiber composite components, the fiber composite components are connected to each other with their end faces. For this purpose, for example, a pipe with an inner diameter is used as the connecting device, which corresponds to the outer diameters of the fiber composite components to be joined and glued to them. In both T-joints and I-joints, fibrous material can be used as an alternative bonding device, which, for example, is wound onto a region of the attachment site and impregnated with a matrix material.

Known types of connection of fiber composite components have the disadvantage that additional connecting devices for connecting the fiber composite components are required. These connection devices must be manufactured in separate manufacturing processes as well as stored, provided and assembled. This results in high manufacturing storage and assembly costs. Furthermore, special connection devices, in particular cuffs or tubes, are required for differently formed connection points, which differ in shape and size. This can lead to a high variety of parts and an associated risk of confusion of connecting devices. Furthermore, a connection of the connecting device by gluing is often a structural weak point, which can lead to failure of the fiber composite component complex at the connection point, in particular to a tearing of the cuff under high load. Finally, sleeves to ensure sufficient stability of the fiber composite component complex require a high additional cost of materials and cause an excessive local increase in size of the fiber composite component complex in the region of the connection point.

It is therefore an object of the present invention, the disadvantages described above in a fiber composite component complex or in the context of the production of a fiber composite component complex to fix or at least partially correct. In particular, it is the object of the present invention to provide a winding core for receiving fibers for producing a connection section having a fiber composite component, a manufacturing method for producing a fiber composite component with a connection portion, a production method for producing a fiber composite component of at least one first fiber composite component and at least one attachment component and a Fiber composite component complex to provide that in a simple and cost-effective manner, an improved, in particular space-saving, material-saving, safe and / or easy to produce, allow connection of a fiber composite component with a connection component or have.

The above problem is solved by the claims. Accordingly, the object is achieved by a winding core for receiving fibers for producing a fiber composite component having a connection portion having the features of claim 1, a manufacturing method for producing a fiber composite component having a connection portion for connecting a connection component to the fiber composite component having the features of claim 6 A production method for producing a fiber composite component complex of at least one first fiber composite component and at least one connection component with the features of claim 13 and by a fiber composite component complex with at least one fiber composite component and at least one connected to the fiber composite component attachment component having the features of claim 15. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the winding core according to the invention apply, of course, in connection with the manufacturing method according to the invention, the generation method according to the invention and the fiber composite component complex according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference or can be.

According to the first aspect of the invention, the object is achieved by a winding core for receiving fibers for the production of a fiber composite component having a connection portion. The winding core has a core body for receiving fibers for producing a component main body of the fiber composite component. According to the invention, the winding core has a core attachment body for receiving fibers for producing the connection section of the fiber composite component, the core attachment being connected to the core body via a coupling section in such a way that after the fibers have been arranged on the winding core, the core attachment can be separated from the core body at the coupling section.

The winding core is useful for shaping the fibers, e.g. Carbon fibers, aramid fibers, glass fibers or the like formed. By winding or braiding the fibers can be arranged on the winding core. 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 attachment, which is connected via a coupling interface to the core body, for example, integrally formed with this, glued to this, hooked to the core body, bolted or the like. Thus, the core additive body is separable at the coupling interface with simple means of the core body.

The core body corresponds to a winding core for producing a conventional fiber composite component, which has no connection portion. Preferably, the core body is formed such that it is easily removed again from the finished fiber composite component, without thereby the fiber composite component must be damaged. It is therefore preferred that the core body has a shape that allows extraction from the fiber composite component. Alternatively or additionally, the core body may be easily destructible, so that it can be removed by destruction of the fiber composite component. The core body is preferably formed as a foam or as a water-filled body.

The core supplement body is designed for the production of a connection portion of the fiber composite component. By means of the core additional body at least one fiber arrangement can be achieved, from which the connection section, for example by means of a preforming tool in a preforming process, can be shaped. Fibers can be arranged for this purpose on the core filler body, for example, to this wound or braided. An attachment section is a section that is designed to connect a connection component, such as a further fiber composite component. The connection section has a contact surface for the attachment of the connection component. Preferably, the connection portion is formed to hold the attachment member positively in a plurality of directions relative to the fiber composite component, preferably such that the attachment member can be arranged in only one joining direction to the attachment portion as well as in a joining direction opposite separation direction of the Connection section is removable. The attachment section thus replaces a conventional connection device, such as a collar, a retaining plate or the like.

Furthermore, the core filler body is formed removable from the core body and from the arranged fibers. For this purpose, the core filler body, for example, a corresponding shape, which promotes extraction of the wound core additive body of the fibers or at least not hindered, e.g. by undercuts. Alternatively or additionally, the core filler body can be easily destroyed, so that it can be removed by destruction from the fibers. Under an easily destructible core additive body according to the invention, a core additive body understood that by thermal action, in particular heat, meltable and / or vaporizable or diffusible. Preferably, an easily destructible core filler in the context of the invention means that the core filler is easier to destroy than the core body.

The core filler body is preferably formed as a foam, water-filled body or simple plastic part.

By means of such a winding core, fiber composite components can be produced in a simple and cost-effective manner, which have a connection section for connecting a connection component, such as a connection element. a further fiber composite component, have. For the production of a fiber composite component complex, the use of additional connecting devices is thus no longer necessary. Thus, work steps can be saved in the production of the fiber composite component complex. Furthermore, by means of the connecting portion, a material insert for producing the fiber composite component complex can be reduced, since less material is required for the production of the connecting portion than for the production of a connecting device. This can further reduce costs. Moreover, the integral formation of the attachment portion with the fiber composite component enables improvement in the strength of the fiber composite component complex. Furthermore, the fiber composite component complexes that can thus be produced have smaller external dimensions at the connection section than conventional fiber composite component complexes with additional connection devices.

According to a preferred further development of the invention, it can be provided in a winding core that the core additive body 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 extension than an extension of the body in at least one direction transverse to a longitudinal extension direction of the core attachment End section has. According to the invention, a longitudinal extension of the core additional body is understood in particular to mean a direction which points 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 filler body has a grading change of the extension from the end portion to the intermediate portion. This facilitates removal of the core filler from the fibers.

Preferably, the core filler has a core filler thickness that is less than a core body thickness of the core body. The core base body is therefore preferably for producing a hollow component and the core filler body for producing a wall which is deformable by preforming to the connection portion.

It is inventively preferred that the coupling portion is formed as a predetermined breaking point. Such a predetermined breaking point preferably has a geometric configuration with increased notch effect, such. at least one acute angle or at least one notch at an acute angle, on. Alternatively or additionally, the predetermined breaking point may have a reduced cross-sectional area. The predetermined breaking point may alternatively or additionally comprise an altered chemical composition as the core body or the core filler body, such as e.g. a relatively weak adhesive, which is arranged between the core body and core filler body. For example, a low adhesion adhesive is an adhesive that forms a bond that is easy to dissolve, such as adhesive. manually, preferably without additional aids, by heating or by vibrations. Predetermined breaking points have the advantage that a detachment of the core filler body from the core body is thus facilitated. The risk of damage to the fiber assembly due to detachment of the core filler from the core body is thus reduced.

It may be provided according to the invention that the core filler body is arranged on an end face or on a flank region of the core body. In this way, differently configured connections between fiber composite components can be achieved. Particularly preferred is an arrangement of the core additive body on an end face of the core body, since thus a good connection of a flank region of a connection component can be achieved.

According to a second aspect of the invention, the object is achieved by a manufacturing method for producing a fiber composite component with a connection section for connecting a connection component to the fiber composite component. The manufacturing process comprises the following steps:

• Providing a winding core according to the invention,
• Producing a fiber arrangement by arranging fibers on the winding core, wherein a base fiber arrangement is produced on the core body and an additional fiber arrangement is produced on the core attachment body,
• Removing the core filler of the winding core from the additional fiber arrangement,
• Preforms of the additional fiber arrangement by means of a molding tool,
• - Impregnating the fiber assembly with a matrix material, and
• - Hardening of the matrix material for producing the fiber composite component.

The winding core according to the invention is preferably mounted on a fiber arranging device for arranging fibers on the winding core, e.g. a winding device or a braiding device provided. Subsequently, by means of the fiber arranging device, a fiber arrangement is produced on the core body and the core filler by adding fibers, in particular continuous filaments. The fiber arrangement arranged on the core body is referred to as a base fiber arrangement and the fiber arrangement arranged on the core supplementary body as an additional fiber arrangement. The generation of the fiber arrangement can be effected for example by braiding, winding or the like.

Subsequently, the core additive body is separated from the body. This is preferably done at a time when the additional fiber assembly is completed or substantially completed. Subsequently, the core additive body is removed from the additional fiber assembly. The removal can also take place according to the invention during preforming. In the context of the invention, a core filler body which is deformed in the context of preforming and thus becomes part of the connection section is also considered removed.

In a subsequent method step, the connection section is produced from the additional fiber arrangement by preforms by means of a preforming tool. In this case, the fibers of the additional fiber arrangement are preferably compressed and brought into a shape of the connection section. The attachment portion preferably has a concave or substantially concave shape for secure reception of the attachment component. Thus, detachment of the connection component from the connection section is limited in a form-fitting manner, at least in several directions. The preforming preferably takes place substantially locally with the additional fiber arrangement.

It can be provided that during preforming a portion of the base fiber assembly, which is adjacent to the additional fiber assembly is also pre-formed.

The fiber assembly, that is the base fiber assembly, as well as the pre-formed auxiliary fiber assembly are then bonded to a matrix material, such as e.g. a thermosetting matrix material, in particular a resin or a thermoplastic matrix material, impregnated. This is preferably done in a transfer molding tool. It can also be provided that the impregnation takes place before or during the preforming. After curing of the matrix material, a fiber composite component with connection portion is finished. According to the invention, further processing steps, such as e.g. Removing the core body from the fiber composite component, pressing the component body or the component body and the connection portion before and / or after and / or after impregnation, trimming of protruding fibers, deburring or the like, be provided to improve the fiber composite component in the production process of the invention. Preferably, the completion of the fiber composite component takes place by means of a transfer molding process.

In the described manufacturing method, all advantages that have already been described for a winding core for receiving fibers for the production of a connection portion having fiber composite component according to the first aspect of the invention. Consequently, by means of the inventive manufacturing method according to the invention fiber composite components can be produced by simple means as well as cost-effective, which have a connection section for connecting a connection component, such as another fiber composite component. For the production of a fiber composite component complex, the use of additional connecting devices is thus no longer necessary. Thus, work steps can be saved in the production of the fiber composite component complex. Furthermore, by means of the connecting portion, a material insert for producing the fiber composite component complex can be reduced, since less material is required for the production of the connecting portion than for the production of a connecting device. This can further reduce costs. Moreover, the integral formation of the attachment portion with the fiber composite component enables improvement in the strength of the Fiber composite component complex. Furthermore, the fiber composite component complexes that can thus be produced have smaller external dimensions at the connection section than conventional fiber composite component complexes with additional connection devices.

Preferably, the fiber assembly is created by braiding. This is preferably done on a braiding device designed for this purpose. By braiding, a braid is created in which the fibers are intertwined. Such braids may, for example, have particularly advantageous isotropic and / or anisotropic mechanical properties. As a result, fiber composite components can be produced, which are optimally designed for certain load conditions. Furthermore, by means of braiding a fiber arrangement can be produced, which has a high intrinsic stability and high mechanical strength and is particularly suitable for further processing into a fiber composite component.

It is inventively preferred that the base fiber assembly and additional fiber assembly is produced as a continuous fiber assembly. In the context of the invention, a continuous fiber arrangement is understood to mean a fiber arrangement in which at least part of the fibers is associated both with the base fiber arrangement and with the additional fiber arrangement. These fibers thus extend partially across the base fiber assembly and partially over the additional fiber assembly. Preferably, the fiber arrangement is designed such that between the base fiber array and the additional fiber array no joints are formed. As a result, a cohesion of base fiber assembly and additional fiber assembly is improved.

In an advantageous development of the production method according to the invention, a binder is applied at least on the additional fiber arrangement prior to preforming. The binder is designed to bind the fibers of the additional fiber assembly to each other, so that the additional fiber assembly has an increased dimensional stability than fibers without binder. The application of the binder is carried out according to the invention at least before the preforming is completed. It can be provided according to the invention that the core additive body already has the binder before the fiber arrangement is produced, or is formed as a binder. More preferably, the preforms are made such that the binder hardens during preforming or at least partially cures. As a result, it is ensured by simple means as well as inexpensively that the additional fiber arrangement does not relax again after the preforms and thus the connection section deforms.

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 can be hardened or hardened by cooling. By means of such a thermoplastic adhesive is a preforming under temperature easily possible. Furthermore, a dimensional stability of the connection section can be achieved by cooling the pre-formed connection section.

According to a preferred embodiment of the method, heat is introduced into the additional fiber arrangement during preforming. This is particularly advantageous when using a thermoplastic binder, since a viscosity of the binder can be reduced by heating.

It is preferably provided according to the invention that the preforming and impregnation are carried out in the same molding tool, such as e.g. a transfer molding tool. Preferably, the mold is not opened between the preforming and the impregnation. Such a molding tool has the advantage that fewer work steps are required to carry out the method. Removal of the fiber arrangement after preforming from a preforming tool and insertion of the fiber arrangement in a transfer molding tool are eliminated. As a result, manufacturing costs of fiber composite components can be reduced by simple means.

Hierbei wird zunächst ein erstes Faserverbundbauteil mittels eines erfindungsgemäßen Herstellungsverfahrens hergestellt. Anschließend wird das Anbindungsbauteil an dem Anbindungsabschnitt des ersten Faserverbundbauteils angeordnet und fixiert. Durch das Anordnen ist das Anbindungsbauteil zumindest in mehrere Richtungen formschlüssig an dem ersten Faserverbundbauteil gehalten. Das Fixieren erfolgt insbesondere durch Verkleben mittels eines Klebstoffs und/oder durch Verklemmen, wie z.B. mittels einer Schelle oder dergleichen. According to a third aspect of the invention, the object is achieved by a production method for producing a fiber composite component complex from at least one first fiber composite component and at least one attachment component. The production process comprises the following steps:

• - Producing at least one connecting portion having a first fiber composite component by means of a manufacturing method according to the invention, and
• - Arranging and fixing the connection component at the connection portion of the first fiber composite component.

Here, first, a first fiber composite component is produced by means of a manufacturing method according to the invention. Subsequently, the connection component is arranged and fixed on the connection section of the first fiber composite component. By arranging the connection component is held at least in several directions form-fitting manner on the first fiber composite component. The fixing takes place in particular by bonding by means of an adhesive and / or by jamming, such as by means of a clamp or the like.

In the described production method, all the advantages already described for a winding core for receiving fibers for the production of a connection portion having fiber composite component according to the first aspect of the invention and in a manufacturing method for producing a fiber composite component with a connection portion according to the second aspect of the invention have been. Consequently, by means of the generation method according to the invention fiber composite component complexes can be produced by simple means as well as inexpensively, in which at least one fiber composite component is connected via a connection portion to a connection component, such as a further fiber composite component. To produce the fiber composite component complex, the use of additional connectors is not required. Thus, work steps can be saved in the production of the fiber composite component complex. Furthermore, by means of the connecting portion, a material insert for producing the fiber composite component complex can be reduced, since less material is required for the production of the connecting portion than for the production of a connecting device. This can further reduce costs. Moreover, the integral formation of the attachment portion with the fiber composite component enables improvement in the strength of the fiber composite component complex. Furthermore, the fiber composite component complexes thus produced have smaller external dimensions at the connection portion than conventional fiber composite component complexes with additional connection devices.

It is preferred that the connection component is formed as a second fiber composite component. The second fiber composite component may have a connection section for connecting a further connection component. It can be inventively provided that the second fiber composite component has no connection portion. The fiber composite component complex preferably has a plurality of second fiber composite components, which are connected to the first fiber composite components via such attachment portions, which are each formed integrally with a first fiber composite component.

According to a fourth aspect of the invention, the object is achieved by a fiber composite component complex. The fiber composite component complex has a first fiber composite component with a component main body and a connection portion and a connection component, which is attached to the connection portion. The fiber composite component complex is produced by means of a production method according to the invention. The connection portion is thus formed integrally with the component main body.

In the described fiber composite component complex, all the advantages already present for a winding core for receiving fibers for the production of a connection portion having fiber composite component according to the first aspect of the invention, in a manufacturing method for producing a fiber composite component with a connection portion according to the second aspect of the invention and a production method for producing a fiber composite component complex according to the third aspect of the invention have been described. Consequently, the fiber composite component complex according to the invention can be produced by simple means as well as inexpensively. Moreover, the fiber composite component complex has high stability because at least one fiber composite component is connected via a connection portion to a connection component such as a connection member. another fiber composite component is connected. The fiber composite component complex does not require any additional connection devices. Thus, work steps can be saved in the production of the fiber composite component complex. Furthermore, by means of the connecting portion, a material insert for producing the fiber composite component complex is reduced, since less material is required for the production of the connection portion than for the production of a connecting device. This can further reduce costs. Moreover, the integral formation of the attachment portion with the fiber composite component enables improvement in the strength of the fiber composite component complex.
