Description

The invention relates to a method for producing a joint component with an outer joint part and an articulated in this joint inner joint comprehensive joint, the outer joint part at least partially enclosing insert and a joint receiving component made of fiber composite material, in which the insert is embedded. Furthermore, the invention relates to such a joint component.

From the DE 20 2004 019 733 U1 a ball joint is known in which a ball joint housing has a spaced from a ball of the ball joint housing part, a gap between the ball and the housing part filled with plastic and the housing part is at least partially enclosed by plastic.

Of the DE 10 2014 214 827 A1 discloses a method for producing a handlebar, in which a preform structure with load-adapted fiber orientation is created, the preform structure is introduced into a forming tool, the preform structure is consolidated and the handlebar is subsequently removed and further processed.

From the DE 10 2011 079 263 A1 a connection arrangement is known in which from a bearing element and a connection region an insert is formed, which is enclosed by means of a casting, from which a structural component and an inner joint part extend out.

In the automotive industry, especially in the chassis sector, fiber-reinforced plastic composites (FKV materials) are increasingly coming to the fore. Their specific properties enable considerable weight savings with identical or even better material properties compared to conventional materials. In addition, there is the possibility of functional integration during the manufacturing process. In order to absorb external loads or to integrate chassis components, force introduction elements are used in fiber-reinforced plastic components. These are often made of metal because of the complex stress state at the point of introduction. In the FKV sector, a distinction is made fundamentally between externally mounted force introduction elements (onserts) and embedded force introduction elements (inserts). The integration of inserts into fiber composite components is currently a major challenge. In order to integrate a joint function in a fiber composite component, predominantly metallic inserts / onserts are currently being used. However, these increase the overall weight of the component and are usually integrated as part of an additional manufacturing step (gluing, riveting, screwing, etc.). In addition, there is a problem in the integration of metallic elements in the resin injection process, which is also referred to as RTM process, where the abbreviation RTM stands for the English term "Resin Transfer Molding". In order to prevent adhesion of the resin-hardener mixture to the metallic tool during demolding, an additive release agent is added to the mixture. By using this release agent, the entire process time can be shortened because the cleaning effort is reduced. This effect occurs undesirably but also in the metallic inserts used in the component. Another problem is the different thermal expansion coefficients of the different materials. Due to the different expansion coefficients, internal stresses are introduced into the component due to the high temperatures during the RTM process. In addition, occur in the field use of the suspension components problems due to external influences. By a potential difference between carbon fibers and metal, e.g. Aluminum, creates corrosion that negatively affects the mechanical properties. In order to prevent this, either the metal surface of the insert has hitherto been aftertreated by the application of so-called primers or the corrosion with the aid of glass fiber spacers has been counteracted.

Proceeding from this, the object of the invention is to be able to avoid at least some of the aforementioned problems.

This object is achieved by a method according to claim 1 and by a hinge component according to claim 13. Preferred developments of this method and / or this joint component are given in the subclaims and in the following description.
