Composite component and process for producing a composite component

摘要

A process is provided for producing a composite component having a first component element and a second component element, which are connected with one another by an adhesive connection. The process includes forming an adhesive cavity by applying thermally active plastic material to an adhesive connection side of the first component element and/or to an adhesive connection side of the second component element; arranging the first component element on the second component element, wherein a gap is formed between the adhesive connection side of the first component element and the adhesive connection side of the second component element, and supplying of heat in such a manner that the thermally active plastic material expands and forms a boundary in the gap between the first component element and the second one. The process further fills the formed adhesive cavity with an adhesive for the permanent connection of the first component element with the second component element.

1. A process for producing a composite component having a first component element and a second component element, the first and second component elements being mutually connected by an adhesive connection, the process comprising the acts of:
forming a locally limited adhesive cavity having a limited axial extent relative to an axial extent of the first and second component elements by:
(i) applying a thermally active plastic material to an adhesive connection side of the first component element and/or to an adhesive connection side of the second component element, the applied thermally active plastic material being applied about a whole circumference of the adhesive connection side at two locations spaced axially apart from one another;(ii) arranging the first component element and the second component element opposite and spaced apart from one another, wherein a gap is formed between the adhesive connection side of the first component element and the adhesive connection side of the second component element; and(iii) supplying heat to expand the thermally active plastic material to form boundaries in the gap between the first component element and the second component element at the two locations, wherein the locally limited adhesive cavity is formed by the gap between the boundaries at the two locations such that the locally limited adhesive cavity has the limited axial extent relative to the axial extent of the first and second com onent elements; and filling the formed locally limited adhesive cavity with adhesive to adhere the first component element with the second component element, the adhesive completely filling the gap between the boundaries.
