Definitions
- the invention relates to a fiber composite component having two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped.
- the invention relates further to a method and an apparatus for producing such a fiber composite component.
- US 2010/0047613 A1 which is incorporated by reference herein, describes a composite brace which comprises a plurality of flat inner composite plies and two stepped inserts which are overlaid with another plurality of flat outer composite plies.
- DE 10 2005 059 933 A1 which is incorporated by reference herein, describes a fiber composite component, in particular a compression-tension strut, comprising: A core element which has at least one concavely constructed face; wherein a passage opening adjoins the at least one concavely constructed face of the core element; and wherein respectively opposite lateral or longitudinal sides of the core element and the side of the passage opening not bounded by the core element are enclosed in a loop-type manner by a fiber composite element, wherein the fiber composite element is a fiber composite element braided in a direction perpendicular to the lateral or longitudinal sides.
- a fiber composite component having two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped, in that a first fiber-reinforced plastics band is wrapped around a first inner element, wherein a second fiber-reinforced plastics band is wrapped around a second inner element, wherein the first and the second fiber-reinforced plastics band are wrapped alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.
- the inner elements which can also be referred to as inserts, are, for example, sleeves, which are formed of metal.
- the inner elements or inserts serve principally for force guidance in a fiber composite of the fiber composite component.
- the inner elements or inserts advantageously comprise a receiver, for example in the form of a through-hole, which, when the fiber composite component is used as a connecting element, in particular as a connecting rod, in the chassis of a motor vehicle, serves to receive a rubber bearing.
- the inner elements can have virtually any desired form.
- the inner elements can be of identical construction.
- the inner elements can, however, also be of different constructions.
- the inner elements can have identical or different diameters. It is essential that the inner elements have an outer contour around which a fiber-reinforced plastics band can be wrapped. For this purpose, the inner elements can be of rotationally symmetrical construction.
- the inner elements can, however, also have the form of, for example, a polygon, the outer faces of which are advantageously convex.
- the fiber-reinforced plastics band is, for example, a tape which is formed of a band-like prepreg material, in particular a CFRP prepreg material. It is also possible to wrap dry fibers around the inner elements and then, at the end of the production process, inject resin into an additional tool.
- the two fiber-reinforced plastics bands can be formed of the same material. If required, the two fiber-reinforced plastics bands can, however, also be formed of different materials and/or comprise different fibers. The two fiber-reinforced plastics bands are first wrapped around the two inner elements independently of one another.
- the two inner elements can, however, also be held at a defined distance relative to one another by a suitable tool during wrapping. After wrapping and curing of the prepreg material, the tool, in particular a corresponding spacer of the tool, can then be removed.
- a preferred exemplary embodiment of the fiber composite component is characterized in that there is arranged between the inner elements an intermediate element around which the first and the second fiber-reinforced plastics band are wrapped alternately.
- the intermediate element is, for example, a pultruded profile.
- the two fiber-reinforced plastics bands are advantageously wrapped alternately around the intermediate element together with the two inner elements. An extremely stable association between the two inner elements with the intermediate element in the fiber composite component is thereby produced.
- a further preferred exemplary embodiment of the fiber composite component is characterized in that the inner elements each have an in particular rotationally symmetrical form with an axis of rotation.
- the inner elements as already described hereinbefore, may be rotationally symmetrical in form but do not have to be rotationally symmetrical in form.
- the axis of rotation coincides, for example, with a longitudinal axis of a through-hole in the inner element.
- the axis of rotation advantageously permits a defined rotation of the inner elements as the respective associated fiber-reinforced plastics band is wrapped around the inner elements.
- the fiber-reinforced plastics band is provided, for example, on a roll, from which the fiber-reinforced plastics band is unwound when the respective inner element is rotated about its axis of rotation.
- the respective associated fiber-reinforced plastics band can thus automatically be wrapped around the inner elements, advantageously in a suitable tool.
- a further preferred exemplary embodiment of the fiber composite component is characterized in that the inner elements each have at least one circumferential depression, which depressions constitute axial securing means for the fiber-reinforced plastics bands.
- the inner elements when seen in longitudinal section, can be, for example, concave in form.
- the inner elements, when seen in longitudinal section, can, however, also comprise an axial portion with a reduced inside diameter, which is delimited by two axial shoulders.
- the circumferential depression advantageously prevents axial migration of the plastics bands during wrapping.
- the first inner element is rotated about its axis of rotation in order to wrap the first fiber-reinforced plastics band around the first inner element
- the second inner element is rotated about its axis of rotation in order to wrap the second fiber-reinforced plastics band around the second inner element
- the first and the second inner element are jointly rotated about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.
- a preferred exemplary embodiment of the method is characterized in that the fiber-reinforced plastics bands are deposited parallel to one another between the inner elements. By unidirectional orientation, a stable fiber composite component which withstands both high tensile and compressive loads is produced.
- a further preferred exemplary embodiment of the method is characterized in that the fiber-reinforced plastics bands are deposited between the inner elements in a crossed association. Different wrapping patterns can be achieved on deposition of the fiber-reinforced plastics bands. Depending on the load that is to be expected, the fiber-reinforced plastics bands can be deposited at different angles relative to one another.
- a further preferred exemplary embodiment of the method is characterized in that a fiber composite material of over-large dimensions in the axial direction is divided, after wrapping, transversely to the axial direction into at least two fiber composite components.
- multiple fiber composite components can thus be produced in one wrapping operation. Dividing is carried out with a suitable separating tool.
- a first rotary drive for the first inner element and a second rotary drive for the second inner element wherein the two rotary drives are attached to a coupling support which is rotatable about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner element with the distance between them.
- the first rotary drive serves to rotate the first inner element in such a manner that the first fiber-reinforced plastics band is wrapped around it.
- the second rotary drive serves to rotate the second inner element in such a manner that the second fiber-reinforced plastics band is wrapped around it.
- the fiber-reinforced plastics bands are thereby advantageously unwound from two mutually independent rolls. After a desired number of plies of the respective associated fiber-reinforced plastics band has been wrapped around each of the two inner elements, the two inner elements are jointly rotated about the third axis of rotation. The two fiber-reinforced plastics bands are thereby unwound from both rolls and deposited alternately, in order to connect the two inner elements to one another. As soon as a desired number of plies of the two fiber-reinforced plastics bands has been deposited, the fiber composite component is finished and then simply has to cure.
- a preferred exemplary embodiment of the apparatus is characterized in that the apparatus comprises at least one pressing roller which serves to constitute a tensioning device for the fiber-reinforced plastics bands between the inner elements.
- the apparatus comprises at least one pressing roller which serves to constitute a tensioning device for the fiber-reinforced plastics bands between the inner elements.
- a looping angle between the fiber-reinforced plastics bands and the inner elements can thus be increased.
- it can be ensured that the fiber-reinforced plastics bands, during wrapping, are in contact with an optional intermediate element between the inner elements.
- a motor vehicle having a fiber composite component described hereinbefore.
- the fiber composite component is, for example, a connecting rod or a coupling element which is installed in a chassis of the motor vehicle.

Both the first fiber-reinforced plastics band 11 and the second fiber-reinforced plastics band 12 are additionally wrapped around the two inner elements 1 , 2 and the intermediate space 5 , or the intermediate element 8 .
- first only the respective associated fiber-reinforced plastics band 11 , 12 is wrapped around the two inner elements 1 , 2 .
- the two fiber-reinforced plastics bands 11 , 12 are then jointly wrapped alternately around the inner elements 1 , 2 so wrapped.
- the fiber-reinforced plastics bands 11 , 12 are preferably tapes of a prepreg material.
- the plastics bands 11 , 12 are reinforced with carbon fibers.
- the corresponding prepreg material is referred to as CFRP prepreg material.
- the fiber-reinforced plastics bands or tapes 11 , 12 are, for example, strips of unidirectional fibers, in particular carbon fibers, which are pre-impregnated with a matrix, in particular an epoxy resin.
- the bands or strips so pre-impregnated are wrapped around the inner elements 1 , 2 .
- the wrapped component is preferably subjected to heat treatment in order that the matrix material, in particular the epoxy resin, with the fibers embedded therein cures.
- the fiber-reinforced plastics bands 11 , 12 are solid and establish a stable connection between the inner elements 1 , 2 .

Abstract
Description
- This application claims priority to German Patent Application No. 10 2021 105 040.5, filed Mar. 3, 2021, the content of such application being incorporated by reference herein in its entirety.
- The invention relates to a fiber composite component having two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped. The invention relates further to a method and an apparatus for producing such a fiber composite component.
- US 2010/0047613 A1, which is incorporated by reference herein, describes a composite brace which comprises a plurality of flat inner composite plies and two stepped inserts which are overlaid with another plurality of flat outer composite plies. DE 10 2005 059 933 A1, which is incorporated by reference herein, describes a fiber composite component, in particular a compression-tension strut, comprising: A core element which has at least one concavely constructed face; wherein a passage opening adjoins the at least one concavely constructed face of the core element; and wherein respectively opposite lateral or longitudinal sides of the core element and the side of the passage opening not bounded by the core element are enclosed in a loop-type manner by a fiber composite element, wherein the fiber composite element is a fiber composite element braided in a direction perpendicular to the lateral or longitudinal sides.
- It would be desirable to simplify the production of a fiber composite component having two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped.
- Described herein is a fiber composite component having two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped, in that a first fiber-reinforced plastics band is wrapped around a first inner element, wherein a second fiber-reinforced plastics band is wrapped around a second inner element, wherein the first and the second fiber-reinforced plastics band are wrapped alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band. The inner elements, which can also be referred to as inserts, are, for example, sleeves, which are formed of metal. The inner elements or inserts serve principally for force guidance in a fiber composite of the fiber composite component. The inner elements or inserts advantageously comprise a receiver, for example in the form of a through-hole, which, when the fiber composite component is used as a connecting element, in particular as a connecting rod, in the chassis of a motor vehicle, serves to receive a rubber bearing. The inner elements can have virtually any desired form. The inner elements can be of identical construction. The inner elements can, however, also be of different constructions. The inner elements can have identical or different diameters. It is essential that the inner elements have an outer contour around which a fiber-reinforced plastics band can be wrapped. For this purpose, the inner elements can be of rotationally symmetrical construction. The inner elements can, however, also have the form of, for example, a polygon, the outer faces of which are advantageously convex. The fiber-reinforced plastics band is, for example, a tape which is formed of a band-like prepreg material, in particular a CFRP prepreg material. It is also possible to wrap dry fibers around the inner elements and then, at the end of the production process, inject resin into an additional tool. The two fiber-reinforced plastics bands can be formed of the same material. If required, the two fiber-reinforced plastics bands can, however, also be formed of different materials and/or comprise different fibers. The two fiber-reinforced plastics bands are first wrapped around the two inner elements independently of one another. This has the advantage, inter alia, that a stable association between the two inner elements and the respective associated fiber-reinforced plastics bands is produced. Thereafter, the two fiber-reinforced plastics bands are then jointly wrapped alternately around the inner elements around each of which a fiber-reinforced plastics band has already been wrapped. An intermediate element can thereby be arranged between the two inner elements. Depending on the design, the intermediate element can remain in the fiber composite component. The two inner elements can, however, also be held at a defined distance relative to one another by a suitable tool during wrapping. After wrapping and curing of the prepreg material, the tool, in particular a corresponding spacer of the tool, can then be removed.
- A preferred exemplary embodiment of the fiber composite component is characterized in that there is arranged between the inner elements an intermediate element around which the first and the second fiber-reinforced plastics band are wrapped alternately. The intermediate element is, for example, a pultruded profile. The two fiber-reinforced plastics bands are advantageously wrapped alternately around the intermediate element together with the two inner elements. An extremely stable association between the two inner elements with the intermediate element in the fiber composite component is thereby produced.
- A further preferred exemplary embodiment of the fiber composite component is characterized in that the inner elements each have an in particular rotationally symmetrical form with an axis of rotation. The inner elements, as already described hereinbefore, may be rotationally symmetrical in form but do not have to be rotationally symmetrical in form. The axis of rotation coincides, for example, with a longitudinal axis of a through-hole in the inner element. The axis of rotation advantageously permits a defined rotation of the inner elements as the respective associated fiber-reinforced plastics band is wrapped around the inner elements. The fiber-reinforced plastics band is provided, for example, on a roll, from which the fiber-reinforced plastics band is unwound when the respective inner element is rotated about its axis of rotation. The respective associated fiber-reinforced plastics band can thus automatically be wrapped around the inner elements, advantageously in a suitable tool.
- A further preferred exemplary embodiment of the fiber composite component is characterized in that the inner elements each have at least one circumferential depression, which depressions constitute axial securing means for the fiber-reinforced plastics bands. To form the circumferential depression, the inner elements, when seen in longitudinal section, can be, for example, concave in form. The inner elements, when seen in longitudinal section, can, however, also comprise an axial portion with a reduced inside diameter, which is delimited by two axial shoulders. The circumferential depression advantageously prevents axial migration of the plastics bands during wrapping.
- In a method for producing a fiber composite component described hereinbefore, the first inner element is rotated about its axis of rotation in order to wrap the first fiber-reinforced plastics band around the first inner element, wherein the second inner element is rotated about its axis of rotation in order to wrap the second fiber-reinforced plastics band around the second inner element, before the first and the second inner element are jointly rotated about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band. Accordingly, in a simple manner, a very stable fiber composite component with two inner elements or inserts which are at a distance from one another can advantageously be produced largely in an automated manner.
- A preferred exemplary embodiment of the method is characterized in that the fiber-reinforced plastics bands are deposited parallel to one another between the inner elements. By unidirectional orientation, a stable fiber composite component which withstands both high tensile and compressive loads is produced.
- A further preferred exemplary embodiment of the method is characterized in that the fiber-reinforced plastics bands are deposited between the inner elements in a crossed association. Different wrapping patterns can be achieved on deposition of the fiber-reinforced plastics bands. Depending on the load that is to be expected, the fiber-reinforced plastics bands can be deposited at different angles relative to one another.
- A further preferred exemplary embodiment of the method is characterized in that a fiber composite material of over-large dimensions in the axial direction is divided, after wrapping, transversely to the axial direction into at least two fiber composite components. Advantageously, multiple fiber composite components can thus be produced in one wrapping operation. Dividing is carried out with a suitable separating tool.
- In an apparatus for producing a fiber composite component described hereinbefore, a first rotary drive for the first inner element and a second rotary drive for the second inner element, wherein the two rotary drives are attached to a coupling support which is rotatable about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner element with the distance between them. The first rotary drive serves to rotate the first inner element in such a manner that the first fiber-reinforced plastics band is wrapped around it. The second rotary drive serves to rotate the second inner element in such a manner that the second fiber-reinforced plastics band is wrapped around it. The fiber-reinforced plastics bands are thereby advantageously unwound from two mutually independent rolls. After a desired number of plies of the respective associated fiber-reinforced plastics band has been wrapped around each of the two inner elements, the two inner elements are jointly rotated about the third axis of rotation. The two fiber-reinforced plastics bands are thereby unwound from both rolls and deposited alternately, in order to connect the two inner elements to one another. As soon as a desired number of plies of the two fiber-reinforced plastics bands has been deposited, the fiber composite component is finished and then simply has to cure.
- A preferred exemplary embodiment of the apparatus is characterized in that the apparatus comprises at least one pressing roller which serves to constitute a tensioning device for the fiber-reinforced plastics bands between the inner elements. On the one hand, a looping angle between the fiber-reinforced plastics bands and the inner elements can thus be increased. In addition, it can be ensured that the fiber-reinforced plastics bands, during wrapping, are in contact with an optional intermediate element between the inner elements. Also described herein is a motor vehicle having a fiber composite component described hereinbefore. The fiber composite component is, for example, a connecting rod or a coupling element which is installed in a chassis of the motor vehicle.
