Abstract

The method for producing a body or chassis component, in which a reinforcing component (4,4a;7,7a) is connected to a mechanical basic body (2,6) via an adhesive, entails carrying out the hardening of the adhesive at least partially by utilizing the residual heat from a previous thermal deformation process of at least the basic body. The reinforcing component is formed by stacked fiber substances (prepregs) which are pre-impregnated by a hardenable synthetic resin. An independent claim is included for a body or chassis component which is produced by the proposed method, wherein the basic body is a A, B or C-pillar, a roof-side frame, a sill or a bumper cross member.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Karosserie- und Fahrwerkbauteilen gemäß den Merkmalen in den Oberbegriffen der Patentansprüche 1 und 13 sowie entsprechende Karosserie- oder Fahrwerkbauteile hergestellt nach dem Verfahren gemäß Patentanspruch 1 oder 13.The The invention relates to a method for producing bodywork and chassis components according to the features in the preambles of claims 1 and 13 and corresponding Body or chassis components made by the process according to claim 1 or 13.

Es ist bekannt, Karosserie- oder Fahrwerkbauteile in Hybridbauweise herzustellen, das heißt einen metallischen Grundkörper mit einem faserverstärkten Kunststoff zumindest bereichsweise zu verstärken, um leichte Strukturen mit verbessertem Crashverhalten kostengünstig herzustellen. Neben den mechanischen und klebetechnischen Verfahren sind auch Möglichkeiten des direkten, formschlüssigen Verspritzens des Kunststoffs bekannt.It is known, body or chassis components in hybrid construction to produce, that is one metallic body with a fiber-reinforced Reinforcing plastic, at least in certain areas, to create lightweight structures to produce cost-effectively with improved crash behavior. In addition to the Mechanical and adhesive techniques are also possibilities direct, positive Splashing of the plastic known.

Die Herstellung von Hybridbauteilen ist fertigungstechnisch relativ aufwendig, da die einzelnen Bauteile miteinander verbunden werden müssen und insbesondere bei Verwendung von Faser-Kunststoff-Verbunden Aushärtezeiten und Klebezeiten zu berücksichtigen sind, welche sich in der Fertigung negativ auf die Taktzeit auswirken.The Production of hybrid components is manufacturing technology relatively consuming, since the individual components are interconnected have to and especially when using fiber-plastic composites curing times and bonding times are, which have a negative impact on the cycle time in production.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Herstellung von Karosserie- oder Fahrwerkbauteilen mit den Merkmalen in den Oberbegriffen der Patentansprüche 1 und 13 aufzuzeigen, bei welchem die Verbindungstechnik besser in den Herstellungsprozess integriert ist und Taktzeiten reduziert werden können.Of these, The invention is based on the object, a method for the production of bodywork or chassis components with the features in the preambles of claims 1 and 13 show at which the connection technology better in the manufacturing process integrated and cycle times can be reduced.

Diese Aufgabe ist bei den Verfahren gemäß Patentanspruch 1 und 13 gelöst.These Task is solved in the method according to claim 1 and 13.

Vorteilhafte Weiterbildungen sind Gegenstand der jeweils abhängigen Unteransprüche.advantageous Further developments are the subject of the respective dependent claims.

Patentanspruch 22 betrifft Karosserie- und Fahrwerkbauteile, die nach einem der Verfahren gemäß Patentanspruch 1 oder 13 hergestellt sind.claim 22 relates to body and chassis components, according to one of Process according to claim 1 or 13 are made.

Ein Verstärkungsteil aus einem Faser-Kunststoff-Verbund benötigt eine bestimmte Aushärtungszeit, die entweder für die Härtung des Klebstoffs oder für die Härtung der Matrix des Verstärkungsteils erforderlich ist. Die Aushärtung des Klebstoffs oder auch der Matrix kann durch eine Temperaturerhöhung beschleunigt werden. Das bedingt jedoch eine Energiezufuhr. Bei der Erfindung ist nunmehr vorgesehen, dass die in der Regel warmumgeformten metallischen Grundkörper beispielsweise in Form einer A-, B- oder C-Säule, eines Dachseitenrahmens, eines Schwellers oder eines Stoßfängerquerträgers im Anschluss an den Warmumformvorgang mit dem Verstärkungsteil verbunden werden, wobei der zeitliche Abstand zwischen der Warmumformung und dem Beginn des Verklebens so gering ist, dass die Restwärme des wenigstens einen metallischen Grundkörpers, der mit dem Verstärkungsteil verbunden wird, zu einer festen Verbindung zwischen dem Verstärkungsteil und dem wenigstens einen metallischen Grundkörper führt. Ziel ist es, einen möglichst raschen und festen Verbund zwischen dem wenigstens einen metallischen Grundkörper und dem Verstärkungsteil zu schaffen, um zumindest sicherzustellen, dass das Verstärkungsteil bis zum nächsten Fertigungsschritt, der beispielsweise in einer kathodischen Elektrotauchlackierung zu sehen ist, hinreichend fixiert ist. Gerade die Fixierung vor dem kathodischen Elektrotauchlackieren ist von besonderer Bedeutung, da auf dem Markt befindliche Lösungen wie konventionelle, zum kathodischen Elektrotauchlackieren geeignete Epoxidharz-Klebstoffe, in einem separaten Fertigungsschritt bis zum Beginn des kathodischen Elektrotauchlackierens fixiert werden müssen.One reinforcing part from a fiber-plastic composite needs a certain curing time, which either for the hardening of the adhesive or for the hardening the matrix of the reinforcement part is required. The curing of the adhesive or of the matrix can be accelerated by an increase in temperature become. However, this requires an energy input. In the invention is now envisaged that the usually hot-formed metallic body for example in the form of an A, B or C pillar, a roof side frame, a sill or a bumper cross member in connection be connected to the hot forming process with the reinforcing member, the time interval between the hot forming and the beginning the bonding is so low that the residual heat of at least one metallic base body, the with the reinforcement part is connected to a fixed connection between the reinforcing member and the leads at least one metallic body. The goal is to be as quick as possible and solid bond between the at least one metallic base body and the reinforcement part to at least ensure that the reinforcement part until the next production step, for example, in a cathodic electrodeposition coating can be seen, is sufficiently fixed. Just fixation cathodic electrocoating is of particular importance because there are solutions on the market like conventional, suitable for cathodic electrodeposition coating Epoxy adhesives, in a separate manufacturing step up must be fixed to start the cathodic electrodeposition coating.

Andere Lösungen, wie das Direkteinspritzen des Faser-Kunststoff-Verbunds sind hingegen noch aufwendiger und setzen eine teure Prozesstechnik voraus. Das Verkleben der Bauteile wird daher als das effizienteste und kostengünstigste Verfahren in der Serienfertigung angesehen.Other Solutions, like the direct injection of the fiber-plastic composite, however, are even more complicated and require an expensive process technology. The Gluing the components is therefore considered to be the most efficient and cost effective Process considered in mass production.

Zur Realisierung der Verbindung zwischen dem wenigstens einen Verstärkungsteil und dem wenigstens einen metallischen Grundkörper wird die Restwärme des Warmumformvorgangs wenigstens eines der genannten metallischen Grundkörper genutzt, so dass entweder ein zwischen dem metallischen Grundkörper und dem Verstärkungsteil angeordneter Klebstoff oder eine entsprechende Matrix des Verstärkungsteils aushärtet oder bei geeigneter Materialwahl sogar beide aushärten.to Realization of the connection between the at least one reinforcement part and the at least one metallic base body, the residual heat of Hot forming process used at least one of said metallic body, so that either one between the metallic body and the reinforcement part arranged adhesive or a corresponding matrix of the reinforcing part cures or even cure both with a suitable choice of material.

Im Rahmen der Erfindung ist es grundsätzlich möglich, das Verstärkungsteil zwischen zwei metallische Grundkörper einzubetten, so dass gewissermaßen eine Sandwichstruktur entsteht. Wenigstens einer der metallischen Grundkörper weist dabei eine hinreichende Restwärme auf, die zur Härtung des Klebstoffs beiträgt. Für eine vollständige Aushärtung des Klebstoffs kann eine separate Wärmezufuhr erforderlich sein. Die zuzuführende Wärmemenge ist jedoch geringer, wenn bereits die Restwärme aus dem vorhergehenden Warmumformvorgang ausgenutzt werden kann und daher zumindest eine sichere Fixierung des Verstärkungsteils ermöglicht wird.in the Under the invention, it is possible in principle, the reinforcing member between two metallic bodies to embed, so to speak a sandwich structure is created. At least one of the metallic ones body has a sufficient residual heat, which is used to cure the adhesive contributes. For one full Curing the Adhesive can be a separate heat to be required. The supplied heat However, it is lower if already the residual heat from the previous one Hot forming process can be exploited and therefore at least one secure fixation of the reinforcement part allows becomes.

Das Verstärkungsteil ist insbesondere von gestapelten, das heißt von mehrlagig angeordneten und mit einem härtbaren Kunstharz vorimprägnierten Faserstoffen, den sogenannten Prepregs gebildet. Bei den Prepregs werden die Verstärkungsfasern exakt orientiert und mit der Harzmatrix kombiniert. Der Fasertyp bestimmt im Wesentlichen die Festigkeit, das E-Modul und andere wichtige Eigenschaften des Faser-Kunststoff-Verbunds. Die gebräuchlichsten Ausgangsstoffe sind Glas-, Aramid-, Graphit- und insbesondere Carbonfasern in Verbindung mit Epoxid- und Phenolharzen. Beim Erwärmen der Prepregs verflüssigt sich das Kunstharz für einen kurzen Zeitraum, wobei die Fasern des Faser-Kunststoff-Verbunds durchtränkt werden. Anschließend beginnt das Kunstharz zu härten. Prepregs haben eine lange Haltbarkeit und eine hohe Lagerfähigkeit. Die chemische Beständigkeit ebenso wie Temperatur- und Witterungsbeständigkeit ist hoch.The reinforcing member is formed in particular of stacked, that is of multi-layered and pre-impregnated with a curable synthetic resin fibers, the so-called prepregs. In prepregs, the reinforcing fibers are exactly oriented and combined with the resin matrix. The fiber type essentially determines the strength, the modulus of elasticity and other important properties of the fiber-plastic composite. The most common starting materials are glass, aramid, graphite and especially carbon fibers in conjunction with epoxy and phenolic resins. As the prepregs are heated, the resin liquefies for a short period of time, saturating the fibers of the fiber-plastic composite. Then the resin begins to harden. Prepregs have a long shelf life and a high shelf life. The chemical resistance as well as temperature and weather resistance is high.

Die Verbindung eines derartig hergestellten Verstärkungsteils mit dem Grundkörper kann dadurch erfolgen, dass Klebstoff auf den wenigstens einen Grundkörper aufgetragen wird und anschließend das Verstärkungsteil auf den mit Klebstoff versehenen Bereichen platziert wird. Der Klebstoff kann mittels Roboter aufgetragen werden oder alternativ als abschließende Außenlage bei einem entsprechenden Gewebe einen Klebefilm bilden. Das heißt, der Klebstoff ist auf die einem Grundkörper zugewandte Seite des Verstärkungsteils aufgetragen. Das bedeutet, dass in einem Prepreg-Stapel unterschiedliche Prepregs verwendet werden. Zumindest ein äußeres, mit dem Grundkörper zu verbindendes Prepreg kann mit einer Klebstoffimprägnierung oder mit einer nach außen weisenden Klebstoffbeschichtung versehen sein.The Connection of such a reinforcing member made with the body can be done by applying adhesive to the at least one body and then the reinforcing part is placed on the areas provided with adhesive. The adhesive can be applied by robot or alternatively as a final outer layer form an adhesive film at a corresponding tissue. That is, the glue is on the one body facing side of the reinforcing part applied. This means that in a prepreg stack different prepregs be used. At least an outside, with the main body To be joined prepreg can with an adhesive impregnation or with an outward be provided facing adhesive coating.

Das Verfahren zur Herstellung des Karosserie- oder Fahrwerkbauteils gliedert sich also in folgende Schritte:
Zunächst werden mehrere Prepregs gestapelt, die vor oder nach dem Stapeln entsprechend der gewünschten Geometrie des wenigstens einen Grundkörpers zuschnitten werden. Anschließend wird das gestapelte Prepreg in einem separaten formgebenden Verfahren zu einer dreidimensionalen Vorform umgeformt. Dieser vorgeformte, dreidimensionale Körper, die Vorform, wird mit einem Klebstoff beschichtet bzw. der Grundkörper wird mit einem Klebstoff versehen. Anschließend wird die Vorform und der wenigstens eine durch den vorhergenden Warmumformvorgang noch warme Grundkörper miteinander verpresst, wobei das Härten des Klebstoffs beginnt. Anschließend werden die Bauteile entweder ausgelagert, um das vollständige Aushärten zu erreichen bzw. um durch Temperaturerhöhung das Aushärten zu beschleunigen. Grundsätzlich sollte die Restwärme zu Beginn des Klebens in einem Temperaturbereich von 100°C bis 200°C liegen.The method for producing the body or chassis component is thus divided into the following steps:
First, several prepregs are stacked, which are cut before or after stacking according to the desired geometry of at least one body. Subsequently, the stacked prepreg is formed into a three-dimensional preform in a separate molding process. This preformed, three-dimensional body, the preform, is coated with an adhesive or the base body is provided with an adhesive. Subsequently, the preform and the at least one by the previous hot forming process still warm body is pressed together, wherein the curing of the adhesive begins. Subsequently, the components are either outsourced to achieve complete curing or to accelerate by increasing the temperature curing. Basically, the residual heat should be at the beginning of gluing in a temperature range of 100 ° C to 200 ° C.

Als Alternative zum separaten Auftragen eines Klebstoffs auf den Grundkörper oder die Vorform ist vorgesehen, dass ein äußeres, mit dem wenigstens einen Grundkörper zu verbindendes Prepreg bzw. eine Prepreglage der Vorform mit einer Klebstoffimprägnierung oder mit einer nach außen weisenden Klebstoffbeschichtung versehen ist. Auf diese Weise entfällt zumindest das separate Auftragen eines Klebstoffs auf den Grundkörper.When Alternative to the separate application of an adhesive on the body or the preform is provided that an outer, with the at least one body to be joined prepreg or a prepregulation of the preform with a adhesive impregnation or with an outward facing adhesive coating is provided. In this way, at least eliminated the separate application of an adhesive on the body.

Das Verkleben des Faser-Kunststoff-Verbunds mit dem Grundkörper erfolgt grundsätzlich in einer zweiteiligen Pressform, wohingegen die Aushärtung des Klebstoffs außerhalb der Pressform insbesondere bei Raumtemperatur erfolgt.The Bonding of the fiber-plastic composite with the base body takes place in principle in a two-part mold, whereas the curing of the Adhesive outside the mold is carried out in particular at room temperature.

Bei Karosserie- oder Fahrwerkbauteilen, die in Sandwichbauweise hergestellt werden, das heißt bei welchen zwischen zwei metallischen Grundkörpern ein Verstärkungsteil aus einem Faser-Kunststoff-Verbund eingebettet ist, kann eine zusätzliche stoffschlüssige Fixierung durch Laserschweißen oder Punktschweißen erfolgen, wobei diese Art der stoffschlüssigen Fixierung insbesondere in Bereichen mit geringer Umformung erfolgt. Diese Bereiche können anschließend einem weiteren Umformschritt unterzogen werden. Mehrere derartiger Verbundbauteile können in weiteren Fertigungsschritten miteinander verbunden werden, so dass nach dem Fügen dieser Karosserie- oder Fahrwerkbauteile eine Art Sandwichstruktur entsteht. Ziel ist es, eine belastungsangepasste Leichtbauweise von insbesondere crashrelevanten Karosserie- und Fahrwerkbauteilen aufzuzeigen.at Body or suspension components made in sandwich construction be, that is at which between two metallic bodies a reinforcing part is embedded from a fiber-plastic composite, can be an additional cohesive fixation by laser welding or spot welding take place, this type of cohesive fixation in particular occurs in areas with low deformation. These areas can then be one be subjected to further forming step. Several such composite components can be connected in further production steps, so that after joining this Body or chassis components a kind of sandwich structure arises. The aim is to provide a load-adapted lightweight construction of particularly crash-relevant Show body and chassis components.

Bei den metallischen Grundkörpern kann es sich um Stahl-, Magnesium-, Titan- oder Aluminiumstrukturen handeln.at the metallic basic bodies it can be steel, magnesium, titanium or aluminum structures.

Mit dem erfindungsgemäßen Verfahren lassen sich besonders vorteilhaft hochbelastete Fahrwerkbauteile verstärken. Erfahrungsgemäß kommt es bei einem Seitencrash eines Personenkraftwagens zu erheblichen Zugspannungen im mittleren Bereich der B-Säule in Richtung Schweller und Dachseitenrahmen. Gerade im Bereich der B-Säule können Verstärkungsteile mit entsprechender Faserorientierung auf sehr kostengünstige und effiziente Weise als Verstärkungen integriert werden. Das Verstärkungsteil kann entweder als Halbzeug gefertigt werden oder als Prepreg aufgelegt werden.With the method according to the invention can be particularly advantageous highly loaded suspension components strengthen. Experience shows it in a side crash of a passenger car to considerable tensile stresses in the middle area of the B-pillar towards sills and roof side frames. Especially in the field of B-pillar can reinforcement parts with appropriate fiber orientation on very cost-effective and efficient way as reinforcements to get integrated. The reinforcement part can be made either as a semi-finished product or as a prepreg become.

Für die Verbindungstechnik, das heißt Verkleben, können sowohl Einkomponenten(1K)- als auch Zweikomponenten(2K)-Systeme genutzt werden. Im Gegensatz zu den 1K-Systemen bieten 2K-Systeme die Möglichkeit einer belastungsgerechteren Auslegung der Verbindung. Eine besondere Anforderung an den Kleber ist die sogenannte KTL-Fähigkeit (KTL = kathodisches Elektrotauchlackieren). Die bislang verwendeten KTL-fähigen 1K-Epoxidharz(EP)-Klebstoffsysteme sind aufgrund ihrer hohen Scherzugfestigkeit bei einer Verbindung eines Verstärkungsteils aus einem Faser-Kunststoff-Verbund mit Stahl aufgrund unterschiedlicher Wärmeausdehnungskoeffizienten als kritisch zu beurteilen. Es wird daher als vorteilhaft angesehen, wenn 2K-Polyurethan(PU)-Klebstoffe zum Einsatz kommen, mit welchen die Energieaufnahme und das maximale Kraftniveau besser einstellbar sind. Der Vorteil der Verwendung von 2K-PU-Klebstoffen ist, dass bei vergleichbaren Crasheigenschaften ein einfacherer Ausgleich der Wärmeausdehnungsproblematik durch die dickeren und flexibleren Klebstoffsysteme erzielt werden kann. Ein großer Vorzug von 2K-PU-Klebstoffen liegt in der Möglichkeit, die Reaktion durch einen Beschleuniger zu beeinflussen, um die Härtezeiten zu verkürzen, was sich ebenfalls positiv auf die Taktzeit des Herstellungsverfahrens auswirkt. Auch 2K-EP-Klebstoffe sind zur Warmaushärtung geeignet.For the bonding technique, ie bonding, both one-component (1K) and two-component (2K) systems can be used. In contrast to the 1K systems, 2K systems offer the possibility of a more load-balanced design of the connection. A special requirement for the adhesive is the so-called KTL capability (cathodic electrocoating KTL). Due to their high shear tensile strength, the KTL-compatible 1K epoxy resin (EP) adhesive systems used hitherto are critical in connection with a reinforcing part made of a fiber-plastic composite with steel due to different thermal expansion coefficients to judge. It is therefore considered advantageous if 2-component polyurethane (PU) adhesives are used, with which the energy absorption and the maximum strength level are better adjustable. The advantage of using 2K PU adhesives is that with comparable crash properties, a simpler compensation of the thermal expansion problem can be achieved by the thicker and more flexible adhesive systems. A great advantage of 2K PU adhesives is the ability to influence the reaction by an accelerator to shorten the cure times, which also has a positive effect on the cycle time of the manufacturing process. 2-component EP adhesives are also suitable for hot curing.

Grundsätzlich erfolgt bei der Verwendung eines Klebstoffs nicht nur eine Erwärmung des Klebstoffs, sondern auch der Matrix, so dass bei entsprechenden Matrix-Kunststoffen auch eine zumindest teilweise Härtung der Polymermatrix erfolgt. Dadurch wird natürlich die Auslagerungszeit weiter reduziert.Basically when using an adhesive not only a heating of the Adhesive, but also the matrix, so that with appropriate matrix plastics also at least partial hardening the polymer matrix takes place. This of course, the outsourcing time further reduced.

Ein weiterer Ansatz, das Verfahren zur Herstellung eines Karosserie- und Fahrwerkbauteils zu verbessern, wird darin gesehen, die Restwärme aus einem vorhergehenden Warmumformvorgang des wenigstens einen Grundkörpers zur Härtung der polymeren Matrix des Faser-Kunststoff-Verbunds zu nutzen. Auch bei dieser Vorgehensweise wird es als vorteilhaft angesehen, wenn die Restwärme zu Beginn des Härtens in einem Temperaturbereich von 100°C bis 200°C liegt. Auch lassen sich die oben beschrieben Sandwichbauteile durch die Anordnung eines Faser-Kunststoff-Verbunds zwischen zwei Grundkörpern herstellen, die ebenfalls zusätzlich stoffschlüssig insbesondere durch Punktschweißen miteinander verbunden werden können. Auch die Verwendung von Prepregs mit entsprechender Matrix einschließlich der Herstellung von dreidimensionalen Vorformen ist analog zu dem eingangs beschriebenen Verfahren möglich, bei welchem die Restwärme zur Härtung des Klebstoffs verwendet worden ist.One Another approach, the method for producing a body and chassis components to improve, is seen in the residual heat from a previous hot forming operation of the at least one base body for hardening use the polymeric matrix of the fiber-plastic composite. Also in this approach, it is considered advantageous if the residual heat at the beginning of hardening in a temperature range of 100 ° C to 200 ° C. Also, let the sandwich components described above by the arrangement of a fiber-plastic composite between two basic bodies produce, which also additionally cohesively in particular by spot welding together can be connected. Also, the use of prepregs with appropriate matrix including the Production of three-dimensional preforms is analogous to the beginning described method possible, in which the residual heat for hardening of the adhesive has been used.

Der Matrix-Kunststoff ist typischerweise ein Duroplast, wie z.B. Epoxidharz. Die Matrix sollte neben dem (härtbaren) Duroplast noch einen (nicht härtbaren) Thermoplasten enthalten, das heißt thermoplastmodifiziert ausgebildet sein. Auf diese Weise ist es möglich, auf den Einsatz von Klebstoff zu verzichten, da der Verbund zwischen dem Verstärkungsteil und dem wenigstens einen Grundkörper durch das als Klebstoff fungierende Matrixsystem realisiert wird.Of the Matrix plastic is typically a thermoset, such as Epoxy resin. The matrix should be next to the (curable) Duroplast still one (not curable) Contain thermoplastics, that is formed thermoplastic modified be. In this way it is possible to dispense with the use of glue, as the bond between the reinforcement part and the at least one main body is realized by acting as an adhesive matrix system.

Die Erfindung wird nachfolgend anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert. 1 zeigt eine perspektivische Ansicht einer Stoßfängeranordnung 1 mit einem Grundkörper 2 in Form eines Stoßfängerquerträgeres und mit endseitigen Crashboxen 3. Im mittleren Bereich des Stoßfängerquerträgers 2 ist ein flächiges Verstärkungsteil 4 angeordnet, das mit den in Richtung zu den Crashboxen 3 weisenden hinteren Enden der Stege des im Querschnitt U-förmig profilierten Stoßfängerquerträgers verbunden ist.The invention will be explained in more detail with reference to the embodiments illustrated in FIGS. 1 shows a perspective view of a bumper assembly 1 with a basic body 2 in the form of a bumper crossmember and with end crash boxes 3 , In the middle area of the bumper cross member 2 is a planar reinforcement part 4 arranged that with the toward the crash boxes 3 facing rear ends of the webs of the cross-sectionally U-shaped profiled bumper cross member is connected.

Die Verbindung erfolgt durch Ausnutzung der Restwärme aus einem vorhergehenden Warmumformvorgang des Grundkörpers.The Connection takes place by utilizing the residual heat from a previous one Hot forming process of the body.

Das Ausführungsbeispiel der 2 unterscheidet sich von demjenigen der 1 dadurch, dass das Verstärkungsteil 4a nicht nur im Bereich der Enden der Stege des Stoßfängerquerträgers verbunden ist, sondern der U-förmigen Konturierung folgt. Dadurch ist eine weitaus größere Fläche des Verstärkungsteils 4a mit dem Grundkörper 2 verklebt.The embodiment of 2 is different from the one of 1 in that the reinforcing part 4a not only connected in the region of the ends of the webs of the bumper cross member, but follows the U-shaped contouring. This is a much larger area of the reinforcement part 4a with the main body 2 bonded.

Die gleichen Prinzipien, wie sie bei der Stoßfängeranordnung 1 zu Einsatz gekommen sind, können auch bei einer B-Säulen-Anordnung 5 angewendet werden. Die 3 und 4 zeigen B-Säulen, die jeweils einen metallischen Grundkörper 6 umfassen, der mit einem Verstärkungsteil 7, 7a aus einem Faser-Kunststoff-Verbund versehen ist. Die Verstärkungsteile 7, 7a sind in diesem Ausführungsbeispiel mit dem metallischen Grundkörper 6, 6a über einen Klebstoff verbunden. Die Aushärtung des Klebstoffs erfolgt zumindest teilweise unter Ausnutzung der Restwärme aus einem vorhergehenden Warmumformvorgang.The same principles as in the bumper assembly 1 can also be used with a B-pillar arrangement 5 be applied. The 3 and 4 show B-pillars, each with a metallic body 6 include that with a reinforcement part 7 . 7a made of a fiber-plastic composite. The reinforcing parts 7 . 7a are in this embodiment with the metallic body 6 . 6a connected via an adhesive. The curing of the adhesive takes place at least partially by utilizing the residual heat from a previous hot forming process.
