Description

The present invention relates to a connecting element for connecting a fiber composite component to a second component, wherein the connecting element has a base body, on which at least one anchoring means for anchoring the connecting element in the fiber composite component and at least one fastening means for fixing to the second component are arranged, and one of a Such a connecting element and a fiber composite component existing semifinished product and a respective method for producing and connecting the semifinished product with the second component.

From the EP 1 508 429 A1 is a connection element made of a fiber-reinforced plastic for connecting two structural components of plastic known. The connecting element has a pin-shaped element projecting from the structural component and also a foot part with a foot extension widening in relation to the pin-shaped element. The pin-shaped element is used to produce a positive and / or non-positive rivet-like connection of the structural component with a second component. The foot part connects to the pin-shaped element and is integrally anchored in the structural component. The disadvantage here is that this integral anchoring of the foot part in the structural component so far only with a concomitant damage to the fibers of the structural component can be realized. Such structure-damaged fiber composite components are thus not nearly as strong as intact fiber composite components.

The object of the present invention is thus to provide a connecting element which does not damage its fiber structure when connected to a fiber composite component, so that the strength of the fiber composite component is not impaired.

The object is achieved by products and methods having the features of the independent patent claims.

According to the invention, the connecting element for connecting a fiber composite component to a second component has a base body on which at least one anchoring means for anchoring the connecting element in the fiber composite component and at least one fastening means for fastening to the second component are arranged. The anchoring means is designed as at least one extension which extends from the base body in the direction of the fiber composite component provided for this purpose. The extension has such a tapering free end, that the fiber composite component is permeable without damage. For this purpose, the free end is particularly thin and / or pointed, so that it can penetrate into the free spaces of the fiber structure. Advantageously, this does not damage the substantially continuous fiber structure of the fiber composite component, so that there is no impairment of the strength of the fiber composite component. Furthermore, a very high-load connection between connecting element and fiber composite component can thus be made very quickly and easily, whereby the manufacturing cost can be reduced.

Advantageously, the free end of the extension is substantially thinner than free spaces between adjacent fibers of the fiber composite component provided for this purpose, so that the fibers can be penetrated without damage.

It is equally advantageous if the base body has a base surface on which the at least one anchoring means is arranged.

It is particularly advantageous if the extension has a bending region, so that it can be bent in such a way after penetrating the fiber composite component provided for this purpose that a fixed positive connection is created between the connection element and the fiber composite component. The bending of the extension is advantageously a quick and easy way to establish a firm connection between the connecting element and fiber composite component can.

In order to avoid damage to the fiber structure of the fiber composite component, it is particularly advantageous if the cross section of the extension tapers in the direction of its free end. Thus, the extension formed in particular as a mandrel can penetrate with its particular very thin formed free end in the very small gaps in the fiber structure, without damaging them. As a result of the cross section widening in the direction of the base body, the fibers of the fiber composite component are forced apart during further forward sliding in such a way that a sufficiently large opening is created in which the extension can essentially penetrate completely such that the base body comes into contact with the fiber composite component to be connected thereto comes. A further advantage of the cross section widening in the direction of the free end is that the area of the extension adjoining the base body is wider and therefore more stable in terms of dimensions and, as a result, can withstand greater loads. The cross section of the extension can have any shape, in particular a round, rectangular, elliptical, trapezoidal and / or hexagonal shape. Furthermore, the extension may be straight and / or have a bend.

It is particularly advantageous if at least two extensions in the region of the outer edge of the Basic body, which is in particular cylindrical, are arranged. Thus, a rotation of the connecting element can be substantially excluded.

It is also advantageous if the base body is round, as this allows an optimal arrangement of the extensions is possible. The main body can also have any other arbitrary shape.

In order to avoid projections in the state connected to the fiber composite component on the side of the fiber composite component facing away from the connecting element, it is particularly advantageous if the base body has at least one recess on its side assigned to the extension or on the base surface. Thus, areas of the fiber composite component can advantageously be formed in the recesses during bending of the projections such that the side facing away from the connecting element of the fiber composite component even in the connected state is flat or portions of the extensions and / or the fiber composite component does not protrude above the level of the remaining fiber composite component ,

In this regard, it is particularly advantageous if the recess of an extension is arranged substantially adjacent to this. Thus, due to the bending of the extension, the corresponding area of the fiber composite component is ideally formed in the adjacent recess. By thus avoiding unevenness in the connection region of the fiber composite component with the connecting element, the fiber composite component can be easily connected to a further component, in particular a carrier component, on its side facing away from the connecting element. For this purpose, it is particularly appropriate to glue the fiber composite component in this area with the carrier component.

In this regard, it is also particularly advantageous if the contour of the recess is substantially modeled on the contour of the extension. If the dimensions of the identical contour of the depression are chosen to be substantially larger than those of the extension, the volume of the depression essentially corresponds to the volume of the fiber composite component which is displaced by the bending over of the extension. As a result, an optimal, ie substantially flat underside of the fiber composite component can be ensured. The recess is thus essentially the negative form of the extension.

It is also advantageous if the fastening means for fastening to the second component is an anchoring means, in particular if the second component likewise has a fiber composite material. Thus, a fiber structure not damaging connection between the connecting element and the second component can also be made here.

It when the fastening means is a shaft which is insertable into an opening of the designated second component and deformable such that the shaft forms a closing head at its end remote from the base body is particularly advantageous. As a result, a positive connection can be established between the connecting element and the second component.

It is likewise advantageous if the shaft has a coaxial bore at its end facing away from the base body, so that the shaft can be opened by means of a punch for the positive connection with the second component. By means of the bore, it is thus advantageously possible to save just as much material that, in particular on the side facing away from the connecting element of the second component provided therefor, elevations due to the bulged shaft are minimized. Furthermore, a substantially planar closing head can thereby be formed.

To avoid elevations, which may arise, for example, by the trained closing head, it is particularly advantageous if the base body has on its side associated with the fastening means a hollow edge. Thus, in the formation of the closing head areas of the second component can be formed in this hollow. The closing head associated side of the second component thus remains flat.

According to the invention, the semifinished product has a fiber composite component and at least one connecting element for connection to at least one second component. The connecting element has a base body, on which at least one anchoring means and at least one fastening means for fastening to the second component are arranged. The anchoring means connects the connecting element with the fiber composite component in a form-fitting manner. For this purpose, the anchoring means is formed as an extension, which extends from the base body in the direction of the fiber composite component and is formed at its free end such that the fiber composite component is penetrated without damage. Advantageously, as a result, the fiber structure of the fiber composite component is not damaged, so that the fiber composite component due to the connection with the connecting element has no loss of strength.

It is particularly advantageous if the extension in penetrated fiber composite component in a bending region is bent such that there is a positive connection between the connecting element and fiber composite component. This connection form is very fast and easy to implement.

It is also advantageous if the extension is bent in the direction of an adjacent recess of the connecting element, so that the fiber composite component is at least partially formed in the recess. This avoids that the fiber composite component on its side facing away from the connecting element has elevations and thus is substantially planar.

In order to create the largest possible contact area when attaching the semifinished product to a second component provided for this purpose, it is particularly advantageous if the fiber composite component has a compensation layer, in particular a spacer foam, on its side assigned to the connecting element. Thus, compressive forces are not only used in the area of the connecting elements of the fiber composite component on the designated second component, but over the entire surface.

In order to avoid slippage of the compensation layer, it is particularly advantageous if the compensation layer is firmly connected to the fiber composite component, in particular glued.

In this regard, it is also advantageous if the compensation layer has a recess in which the main body of the connecting element is arranged, wherein the main body and the compensation layer are substantially equal thickness.

It is likewise advantageous if the semifinished product is designed as an adhesive tape, the side of the fiber composite component assigned to the connecting element and / or the compensating layer being coated with adhesive. Thus, the semifinished product can be provisionally attached to the second component prior to forming the closing head. Slippage is thus essentially excluded.

It is particularly advantageous if the side of the fiber composite component facing away from the connecting element has a connection region in which the semifinished product can be connected to a further component, in particular a carrier component. In this case, the semi-finished product can be glued to the carrier component in the connection region, for example.

In a method according to the invention for producing a semifinished product, at least one connecting element is positively connected to at least one fiber composite component. Here, an anchoring means of the connecting element is first inserted through the fiber composite component, wherein the anchoring means passes through the fiber composite component damage free with its free end until the fiber composite component facing side or the base of the anchoring means rests on the fiber composite component. Subsequently, the anchoring means is bent in a bending region such that a positive connection is produced between the fiber composite component and the connection component. Advantageously, the fiber structure of the fiber composite component is obtained without damage in this manufacturing process, so that the strength of the fiber composite component remains unaffected.

It when the anchoring means are at least partially bent in the direction of adjacent recesses of the body is particularly advantageous. The depressions are arranged on the base of the base body. In this way, it is advantageously avoided that portions of the anchoring means and / or the fiber composite component over the level of the connection region of the fiber composite component survive. As a result, the halfway thus has a substantially planar bottom.

In a method according to the invention for connecting a semifinished product to a second component, a shaft of the semifinished product is guided with its end through an opening of the second component. Subsequently, the end is deformed by means of a punch such that a closing head is formed in this region of the shaft, which produces a positive connection between the semifinished product and the second component. In this embodiment of the closing head, regions of the second component are formed into a hollow section of the semifinished product in such a way that the second component, on its side facing away from the semifinished product, is substantially planar together with the closing head. Thus, more components can advantageously be arranged on the side facing away from the semifinished side of the second component, which advantageously lie flat on the second component, since elevations are substantially avoided by this molding in the hollow section of the semifinished product.

It is also advantageous if the punch is pressed into a coaxially arranged at the end of the shaft bore, so that the shaft auftulpt to the closing head. As a result, a false, in particular eccentric application of the stamp is substantially avoided, which could result in an asymmetrical and thus substantially non-planar design of the closing head.

Furthermore, it is advantageous if the semifinished product before the positive connection with the second component in a connection region with a support member, in particular a closed Profile has, connected, in particular glued. As a result, a damage-free connection between the carrier component and semifinished product is advantageously ensured.

It is particularly advantageous if a protective cap is attached above the shaft and / or the hollow edge of the semifinished product and the semifinished product is subsequently impregnated with resin and cured to a hard matrix.

By the protective cap is avoided that the arranged at the end of the shaft bore and / or the hollow is filled with resin.

It is also advantageous if the at least one anchoring means is bent in the direction of an adjacent recess of the connecting element, so that regions of the fiber composite component are formed in this recess. This ensures that the side facing away from the connecting element of the fiber composite component remains substantially flat.

Further advantages of the invention are described in the following exemplary embodiments. It shows:

8th and 9 a section through a connection area of a specific application.

1 shows a connecting element 1 with a basic body 2 which is substantially cylindrical in the present embodiment. On opposite sides of the body 2 are anchoring means 3 and a fastener 4 arranged. The anchoring means 3 are as extensions 5 trained, different from the main body 2 starting in the direction of a fiber composite component provided for this purpose 6 , this in 2 is shown extending. They have a free end 7 on, which is designed such that the fiber composite component 6 , with which a positive connection is to be made, is damage-free penetrable. For this purpose, the extensions rejuvenate 5 towards their free ends 7 and are formed there pointed or thin. The extensions 5 of the anchoring agent 3 are on the outer edge of the body 2 arranged and each have at least one bending area 8th on, allowing them to positively connect the connecting element 1 with the fiber composite component 6 are bendable radially inward.

In the connected state unwanted elevations on the connecting element 1 opposite side of the fiber composite component 6 To avoid, the body rejects 2 at its the extensions 5 assigned side depressions 9 on. Here is one recess each 9 an extension 5 assigned. The depth of the depression 9 takes off the extension 5 starting in the radial direction of the body 2 towards its central axis. The one for receiving the free end 7 intended receiving area 10 the depression 9 thus has the lowest depth. The contour of the depression 9 is essentially the contour of the extension 5 imitated, so that the recess 9 essentially the negative form of the extension 5 represents.

The anchoring means 3 in relation to the main body 2 arranged on the opposite side fasteners 4 is in the present embodiment as a shaft 11 educated. This is coaxial with the cylindrical base body 2 at the for connecting to a second component 12 , this in 6 and 7 is shown, provided area. The shaft 11 is intended to be reshaped so that between connecting element 1 and the second component 12 a positive connection is made. For this purpose, the shaft 11 one at his base body 2 opposite end a coaxial bore 13 on. The hole 13 is in particular conical and for insertion of an in 6 illustrated stamp 22 intended. In addition, the body indicates 2 at his the shaft 11 associated side a hollow 14 on, in the middle of the shaft 11 is arranged. The depth of the hollow 14 takes off the shaft 11 starting radially outwards.

In a particularly preferred embodiment, this connecting element 1 contemporary 2 . 3 and 4 with a fiber composite component 6 positive fit to a semi-finished product 15 connected. For the production of in 4 shown semifinished product 15 first, the connecting element must 1 as in 2 and 3 shown with the fiber composite component 6 get connected. At this stage, the fiber composite component 6 have not been subjected to any chemical or thermal curing process, so that it is present as a flexible fiber material.

According to 2 is on for connecting to the connector 1 provided side of the fiber composite component 6 a leveling layer 16 arranged. This has recesses 17 on, which is essentially the size of the main body 2 correspond. For connecting the connecting element 1 with the fiber composite component 6 that with the leveling layer 16 is glued, becomes the connecting element 1 in the recess 17 with the anchoring means 3 assigned side ahead. In this case, the anchoring means penetrate 3 respectively the extensions 5 the loose fiber material of the fiber composite component 6 damage-free with their free ends 7 , The height of the leveling layer 16 is essentially equal to the height of the body 2 , so that on for fixing with the second component 12 provided side creates a substantially flat and thus large connection surface.

After the extensions 5 of the connecting element 1 with their free ends 7 according to 2 and 3 by the fiber composite component present in loose fiber form 6 are made according to 4 the positive connection of the connecting element 1 with the fiber composite component 6 , For this purpose, the extensions 5 such in their bending area 8th bent radially inward that areas of the fiber composite component 6 in the continuations 5 adjacent depressions 9 of the connecting element 1 be formed. This has the advantage that at the the connecting element 1 opposite side of the fiber composite component 6 a substantially planar connection area 18 preserved.

Such a semi-finished product 15 can be any number of fasteners 1 exhibit. Furthermore, the arrangement of these connecting elements 1 on the fiber composite component 6 be designed arbitrarily. So can the fasteners 1 for example, single row, multi-row, parallel, offset, symmetrical and / or asymmetric on the fiber composite component 6 be arranged.

Likewise, the semifinished product 15 also be designed as an adhesive tape, wherein at least one side of the semifinished product 15 coated with adhesive, so that it can be temporarily attached to one or more other components before the final fixation. So can the semi-finished product 15 , as in 5 shown on a support member 19 initially provisionally attached. If the carrier component 19 As illustrated in the illustrated embodiment, a closed profile, it is particularly advantageous if the semifinished product 15 with the carrier component 19 is firmly glued. This is the hole 13 as well as the hollow 14 of the connecting element 1 initially with a detachably attached protective cap 20 covered. Then the semi-finished product 15 impregnated with resin, the bore 13 and / or the hollow 1.4 by means of the protective cap 20 protected from sticking with resin. Subsequently, the semifinished product, which is now impregnated with resin 15 in a well-known thermal and / or chemical curing process to a hard fiber composite component 6 hardened, wherein at the same time a material connection with the support member 19 received.

Alternatively, the semifinished product 15 but even as semi-finished impregnated with resin 15 available. In this case, advantageously, the attachment of the protective cap 20 be avoided.

Alternatively, the semifinished product 15 also by means of generally known adhesive method with the carrier component 19 be glued.

To between carrier component 19 and semi-finished products 15 To be able to establish a connection that is as strong as possible, it is important to have a connection area that is as planned as possible 18 to accomplish. This is essentially ensured by the fact that during manufacture of the semifinished product 15 Areas of the fiber composite component 6 by bending over the extensions 5 into the wells 9 be formed so that the connection area 18 is essentially flat. As a result, a very strong connection between semi-finished 15 and carrier component 19 getting produced.

For connecting the semifinished product 15 or the associated carrier component 19 with the second component 12 is according to 6 the shaft 11 of the connecting element 1 through an opening 21 of the second component 12 plugged. Because of the leveling layer 16 is essentially the same height as the main body 2 , the second component can 12 both on the leveling layer 16 as well as on the main body 2 lie flat.

As in 6 is shown, for positive connection of the connecting element 1 with the second component 12 into the hole 13 of the shaft 11 a stamp 22 pressed. This will be the bore 13 provided shaft 11 opened in such a way that according to 7 a closing head 23 is trained. This provides the positive connection between the connecting element 1 and the second component 12 ago. Furthermore, by the stamp 22 applied force areas of the second component 12 in the on the shaft 11 adjacent hollow 14 pressed. This ensures that the connection element 1 opposite side of the second component 12 together with the closing head 23 forms a substantially planar surface. For example, this is particularly the case in 8th and 9 shown, special application from the automotive industry advantageous.

8th shows a cross section through a cross member of an A-pillar. The carrier component 19 serves to compensate for enormous forces, especially in the event of an accident. As a result, the closed structure of the support member must 19 stay intact. For this purpose is at the connection points 24a and 24b a semi-finished product 15a . 15b appropriate.

As previously stated, the semi-finished product 15a . 15b with the carrier component 19 glued and / or so impregnated with resin that it during the chemical and / or thermal curing process with the carrier component 19 a cohesive connection is received. After the semi-finished products 15a . 15b at the connection points 24a . 24b are attached, the second component 12 , which in this specific application is a cover, with the fasteners 1a . 1b the semi-finished products 15a . 15b positively connected. For this, the shafts 11a . 11b the connecting elements 1a . 1b through the corresponding openings provided 21a . 21b of the second component 12 plugged. After that, the fasteners 4a . 4b or the shafts 11a . 11b by means of a stamp 22 so aufgetulpt that between the second component 12 and the connecting elements 1a . 1b a positive connection is made. After that, especially in the area of the connection point 24a on the substantially plan trained, the connecting element 1 opposite side of the second component 12 a windshield 25 glued, this plan on the second component 12 rests.

A detailed view of the connection area 24a is in 9 shown.
