Description

The invention relates to a component, in particular a fiber composite component for a motor vehicle, having a planar body of a fiber composite material, in particular of fiber-reinforced plastic, and an insert inserted into a passage opening of this body with adhesive for passing or attaching connecting elements according to the preamble of claim 1.

Furthermore, the invention relates to an insert for the implementation or fastening of fasteners for gluing into a through hole of a body according to claim 9.

Such an insert, which allows the assembly of lightweight panels is z. B., from the DE 8701020 U1 known. In this case, a bushing is inserted into a bore of a lightweight board with the aid of a device and then shed.

Although this type of female insert provides a good bond between layers of a lightweight board, it is not suitable for introducing higher forces, in particular shear / tensile forces, into the lightweight board. In particular, in the automotive industry but when using lightweight components and their compounds but expected that larger forces can be absorbed and initiated at the joints. Therefore, this type of socket is not suitable for this application.

Currently come as lightweight panels more and more frequently fiber-reinforced, in particular carbon fiber reinforced plastic panels used. Of particular importance are the protection and the electrical insulation of the fibers exposed by a connection bore against penetrating media and against contact with materials of other electrical potentials. In a simple potting a socket there is a risk not to be able to isolate all exposed fibers, z. B. too narrow column, not centered sockets, trapped air, too tough potting compound, etc. Also, therefore, the bush described in the utility model with the corresponding method and apparatus when using fiber composites as a lightweight board is not suitable for use.

It is therefore an object of the present invention to provide a component, which is a performing low-force connection elements, hoses, cables u. Ä. And / or a fastening of force-introducing connecting elements allows, the component to be long-term fulfillment of this task from environmental corrosion and electrical contact corrosion to be protected at least in functional areas.

This object is achieved by a component having the features of patent claim 1 and by an insert having the features of patent claim 9. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.

The component according to the invention comprises a flat body, in particular of a fiber-reinforced plastic, with a passage opening into which an insert is glued. This insert has a resting on the body support ring and a penetrating into the through hole bushing element. Between an inner wall of the passage opening and an outer wall of the sleeve member, a Buchsenspalt is formed, which is wider in a reservoir area between tragringseitigem input of the through hole and Tragringfernem output of the through hole as in an output closer to the output area. The Buchsenspalt is filled circumferentially with adhesive in the output area. The support ring-side entrance of the passage opening is sealed against ingress of environmental influences or the contact between insert and body with adhesive and insulated.

With such a reinforcement of the passage opening of the body, a passage of strand-like elements is guaranteed. In addition, force can be introduced into the component via the bonded to the body support ring by running or fastened fasteners. The special geometry of the insert, in particular the support ring, has the effect of pressing out the excess adhesive applied in the female nip or over the passage opening by its reservoir-limiting property both in the direction of the outer support ring radius and in the direction of the passage opening exit. The excess adhesive content results from the larger volume of applied or incorporated adhesive than is available in the reservoir area in volume. The volume of the reservoir area is fixed after insertion of the insert into the passage opening. In an advantageous embodiment, a pre-applied excess of adhesive during insertion of the insert is first pressed in the direction of the support ring and the input side. The flat support ring geometry then ensures that the adhesive is pushed back towards the reservoir area by the pressure on this excess. Since there is no more fillable volume there, the excess is distributed through the flat geometry of the support ring between the support ring and the body surface and swells out possibly beyond the support ring outside diameter. Of the Supporting ring is thereby connected to the body surface, and the passage opening is sealed at the inlet and outlet sealed with adhesive. In further embodiments with subsequently applied or activated adhesive, the support ring acts as a kind of cover and also ensures an inlet and outlet side dense Verklebungsergebnis. This entry-side and exit-side adhesive seal of the through-hole provides the necessary protection against corrosion to ensure the durability of the connection as an essential feature and improvement over previous solutions.

In addition, the bonded support ring is the element of the insert, which makes it possible to initiate forces ideal shear through the most fiber-reinforced body and thus into the component. Fiber-reinforced bodies require a large area for the introduction of forces. If the area is too small, there is a high tendency for the matrix material to creep, which often leads to failure of the component. The overall geometry of the support ring and bushing form is thus the solution for the task of corrosion-resistant bonding as well as the functional performance in terms of implementation and attachment of fasteners - and the associated force application. At the same time, however, this geometry again leads to the bonding required for the introduction of forces via the support ring. Thus, the solution of the support ring geometry found for the introduction of force influences the bonding quality required for the problem solving corrosion resistance. The dense bonding required for corrosion resistance, in turn, positively influences the subject of force introduction via the support ring. The solution according to the invention is thus inseparably linked in the combination of its individual features.

It is particularly advantageous if the Buchsenspalt is filled annularly in the bearing ring side entrance of the passage opening with adhesive. This ensures that no environmental influences can penetrate the fibers which may be exposed in the passage opening.

• – mechanisch kombiniert: durch Verringerung des Reservoirvolumens beim Einschieben des Einsatzes in die Durchgangsöffnung und einer entsprechenden Buchsen-/Tragringsgeometrie mit vorappliziertem Klebstoff,
• – chemisch und/oder thermisch durch aktivierbaren vorapplizierten Klebstoff oder
• – mechanisch addiert: durch einen nach dem Einfügen des Einsatzes applizierten Klebstoff, der über eine Zugangsöffnung mit Druck in die Spalte eingepresst wird und bei Überfüllung der größeren Spalte durch die entstehende Druckerhöhung bei weiterem Einpressen des Klebstoffs auch in die schmalsten Spalte bis zur Entlastung beim Austreten gepresst wird, wobei dieser Effekt durch geringe Kohäsionskräfte im Klebstoff und hohe Adhäsionskräfte und Kapillarwirkung unterstützt werden kann.

For a continuous over the inner surface of the passage opening corrosion protection, it is advantageous if the Buchsenspalt is completely filled with adhesive. The adhesive has an insulating effect between possibly different potentials of fibers exposed in the wall of the passage opening on the one hand and the material of the insert on the other hand. In addition, adhesive rings would have trapped voids between the through-hole and use of indeterminacy with respect to moisture or foreign matter that might have been trapped in these voids. This can lead to moisture-related corrosion or chemical-mechanical corrosion during operation. The emergence of these indeterminate cavities is avoided by the special bushing geometry, the accurate bore as a through hole and a geometry and bonding process compliant filling and overfilling of the reservoir area with adhesive. To distribute the adhesive in both the narrow gap at the exit area of the passage opening and at the entrance area, the principle of overfilling a reservoir is used. This overcrowding can be achieved

• Mechanically combined: by reducing the reservoir volume when the insert is inserted into the passage opening and a corresponding bushing / support ring geometry with pre-applied adhesive,
• Chemically and / or thermally by activatable pre-applied adhesive or
• - Added mechanically: by an applied after inserting the adhesive, which is pressed through an access opening with pressure in the column and overfilling of the larger column by the resulting pressure increase with further pressing of the adhesive in the narrowest column to discharge on emergence This effect can be supported by low cohesive forces in the adhesive and high adhesion and capillary action.

It is also advantageous if the support ring is glued annularly with a top surface of the body. This can ensure that no contact corrosion between the support ring and body surface can occur. In addition, seals an annular bonding of the support ring and the input side of the passage opening against environmental influences.

A further advantageous embodiment of the invention provides the complete filling of the support ring gap between the underside of the support ring and a surface of the body, because on the surface connection of the support ring with the body large forces can be initiated nondestructive in the component. At the same time, as large an area and annular bonding as possible provides lasting protection against contact corrosion, the penetration of environmental influences, as well as the inclusion of moisture in cavities. Any exposed fibers of the insert and / or the body may be protected by avoiding these influences from contact and / or environmental corrosion caused by conditions rooted under the support ring.

Preferably, the surfaces which are bonded with adhesive are mechanically processed prior to bonding mechanically to an optimum surface roughness for the adhesive, and then chemically cleaned and possibly etched. This type of preparation has the advantage that the opening in the body and the insert can be manufactured with relatively high tolerances, in order to be prepared accordingly only in the actual application. The mechanical and chemical preparation offers an influence on the parameters of surface properties and, if necessary, geometry properties for gap dimension adjustment for an optimum, lasting connection result.

A particularly advantageous embodiment of the invention has been shown using thermally activatable and / or foamable adhesive. The adhesive can be unexpanded, and thus without hindering the insertion process with the necessary for the overcrowding excess volume to be brought into the gap. Only with final positioning of the insert in the passage opening of the adhesive is activated. The result is an all-around uniformly foamed or fixed insert in the passage opening with a secure sealing of the inlets and outlets of the passage opening against environmental influences and potential differences between the insert and the body.

Conveniently, a polymeric material, in particular an epoxy resin is selected for bonding the insert with the body. Extensive experience, easy handling, automatic processing and advantageous properties in the expected for a vehicle component climatic and kinetic conditions of use make this adhesive particularly suitable for use. In addition, this adhesive offers a wide range of properties due to the possibility of adding additives and fillers. In particular, added glass granules offer the possibility to set a certain minimum height of columns for bonding, so that a gap width optimum of 0.35 mm-0.7 mm can be achieved for most epoxy resins to achieve a secure connection. The use of granules ensures that a minimum distance is achieved in the bushing area through the distribution of the adhesive. In addition, these spacers guarantee in a bushing geometry, the mechanical displacement of the pre-applied adhesive requires that not the complete adhesive mass during insertion of the insert or when pressing the support ring can be displaced and thus no unclosed point in the region of the adhesive rings at the inlet and outlet of the through hole , This also ensures a dense and therefore contact and environmental corrosion resistant connection to fulfill the functions. The setting of the optimal adhesive gap height to achieve a good connection performance of the adhesive component is also particularly advantageous for creating a connection of the support ring with the body surface for the adoption of force introduction functions.

The second aspect of the invention relates to an insert which is provided for the passage or fastening of connecting elements for gluing into a passage opening, in particular a flat body of a motor vehicle component made of fiber composite material. The insert comprises a rotationally symmetrical bushing element and a support ring which is integrally connected to the bushing element. In a bearing ring near area, the socket element has a smaller diameter than in a tragringferneren collar area. The outer diameter of the support ring is greater than the maximum outer diameter of the collar portion of the female member. This insert is suitable for mass production as well as for an automated gluing process part, which is characterized by its simple design z. B. can be represented as injection molding or extrusion. The sealing against corrosion-causing influences (eg acids, salts, moisture and potential difference) and the introduction of forces by the insert can be realized by the geometric design of the support ring, bushing and by the creation of a reservoir area, by insertion of the insert is formed in a passage opening with the inner wall of a passage opening and its overfilling with adhesive leads to a reliable closing of the gap formed between the outside of the sleeve member and the passage opening.

In a particularly advantageous embodiment of the bushing of the insert, a steady increase in the outer diameter of a tragringnahen to a tragringfernen area is provided. There is thus room in the area of smaller diameter to apply an adhesive bead. When inserting the bushing into a passage opening of a body, the bush in the waistband area is centered and guided in this passage opening. During the insertion of the bush, the reservoir area is initially completely filled. This is done by an excess of adhesive in the bead and the adhesion forces acting between body, socket and adhesive. In addition, the support ring reduces the volume of the reservoir area when inserting the insert and exerts pressure on the adhesive. Upon further insertion, the excess adhesive is pushed out of the support ring gap as well as towards the waistband area. The adhesive has, on the one hand, a viscosity which, depending on the gap width, on the bushing collar is sufficiently fluid that it can be pressed into this gap by the pressure on the excess adhesive in the reservoir. On the other hand, the adhesive has to be sufficiently tough so that pressure can actually be absorbed by the adhesive in the reservoir area. This will achieved a dense and complete bonding without stripping the adhesive and defects with an empirically confirmed setting of the held adhesive amount.

In a further advantageous embodiment of the invention, the bushing element diameter is constant from the bearing ring near to the tragringfernen area. In the waistband it has a sudden increase in diameter to the maximum sleeve diameter. This shape of the bushing element creates a particularly advantageous reservoir area between the support ring and collar, which can be filled and prepared with tough or firm, later activatable adhesive. The waistband area is useful as a guide when inserted into a through hole. The gap between the waistband and the support ring is safely foamed and filled by activating the adhesive. In addition, no risk of contamination due to adhesive mass occurs during insertion. The insert can be precisely and effortlessly positioned and adhered reliably, tightly and with power transmission.

In addition, an advantageous embodiment of the invention results from the fact that an annular groove which opens to an outer wall of the sleeve member and is located between the support ring and collar region is connected via a leading to a top surface of the support ring filling passage. This allows, after insertion of the insert into a through hole, the groove and over the collar and under the support ring resulting gap areas over the filling with low-viscosity or liquid adhesive to fill, which displaces the air over the gap until the adhesive on the collar area, protruding under the support ring and / or passage port exit. The insertion process and the bonding process can be separated into individual process steps.

It has proven to be particularly advantageous if the support ring tapers in cross-section through a decrease in material relative to its outside diameter. This is achieved in particular by a chamfer on the underside of the support ring. This design allows a steady increase in the elastic adhesive mass under the support ring with simultaneous decrease in the stiffness of the support ring due to lower material thickness. Thus, stress peaks in the introduction of forces on the support ring can be avoided in the body. The insert remains glued to the body when introducing high mechanical forces that would lead to failure of the component under conventional connection construction.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing.

Between a bottom 27 of the carrying ring 13 and the top surface 33 there is a carrying ring gap 25 , This one is with an adhesive 10 with a defined gap gap generating granules 35 filled. The adhesive 10 connects the support ring 13 with the top surface 33 , The support ring 13 indicates from a range of the support ring diameter Dt to a region of the largest outer diameter Dt-max on the underside 27 a chamfer 31 leading to a steadily reducing cross-section Q from the area of the support ring diameter Dt to the area of the maximum outside diameter Dt-max. A tragringnaher socket element area 37 has a minimum sleeve diameter Db-min. In a tragringfernen area, a waistband area 23 , there is a maximum bushing element diameter Db-max. Between these extremes are from support ring to collar steadily increasing socket diameter Db. Between an outer wall 17 of the socket element 15 and an inner wall 9 the passage opening 5 there is a Buchsenspalt 19 with a gap width B. A range of the Buchsenspalts 19 around the tragringennahen female element area 37 is hereafter referred to as reservoir area 21 denotes the area of the body 3 , the waistband area 23 of the female member is opposite to the body side, becomes exit region 22 called.

This embodiment of the female element is particularly suitable for use in relatively short passage openings 5 , The thus designed waistband area 23 is a leader in the field 11 , so that this is easy to thread automatically. For longer passage openings 5 is a longer waistband 23 , due to the required on longer passage length leadership precision advantage. The advantageous for this sleeve geometry adhesive 10 is pasty and viscous, so it is in the range 37 can be applied bead-like before insertion and does not run. The amount of adhesive must also form an excess here, in that the bead volume is at least 1/6 larger than the final reservoir volume after completed insertion of the insert 11 in the body 3 , If the outer diameter of the bead is greater than the diameter of the passage opening 5 Due to its viscous and adhesive-cohesive properties, the bead, with its uniform insertion pressure and resistance to the passage opening, provides a centered fit.

About the filling passage 43 can glue in the groove 39 '' be pressed. Was the use 11 '' so in a through hole 5 positioned that bushing element 15 '' from a gap 19 is surrounded, the glue becomes 10 z. B. with the aid of a robot-controlled filling nozzle 45 filled until the Buchsenspalt 19 is filled and the glue 10 at the waistband area 23 '' and under the support ring 13 '' does well. This embodiment of the insert is particularly advantageous because it is a separation of items (use 11 '' , Body 3 ) of the component 1 and the glue 10 allows and so the parameter amount of adhesive to the filling process to the fit between use 11 '' and passage opening 5 can be adjusted. This embodiment of the insert 11 '' is particularly advantageous where no activation of adhesive by heat or chemicals can take place and by a long through hole insertion of an insert 11 due to the low guidance precision and high likelihood of ligation in short bundles 23 does not offer. In addition, by the subsequent introduction of the advantage that the process steps of the insertion of the bonding process can be separated and the adhesive only in the bonding step poses a risk of contamination of the surfaces and tools. In addition, in particular less viscous and / or highly fluid and fast-setting adhesives can be used here, as a clean and fast introduction into the column by the design of the filling 43 , the groove 39 '' and the collar diameter Db-max '' and the journal-near sleeve outer diameter Db ''.
