Method and device for bonding parts to be joined, as well as component

摘要

A method is provided for producing a bonded joint between fiber-reinforced thermoplastic parts to be joined, in which fiber-containing plastic material is mixed into the joining zone while friction stir welding the parts to be joined in the form of a butt joint. A device for carrying out such a method for a joined component is also provided.

主权项

1. A method for producing a bonded joint between fiber-reinforced thermoplastic parts to be joined, the method comprising:
supporting the parts to be joined on a rotating counter bracket that forms a plate-like head section of a stirring pin, wherein the parts to be joined are supported on their side that faces away from a friction shoulder; positioning the parts to be joined as a butt joint including a joining seam; welding the parts to be joined to one another; and supplying a fiber-containing plastic material into a joining zone, the joining zone defined as a zone where the parts are to be joined to one another, wherein the fiber-containing plastic material is heated above its melting temperature and rubbed into the joining zone by the friction shoulder as it is intermittently lifted relative to the joining zone and the plastic material can be superficially discontinuously supplied to the joining zone underneath the friction shoulder, and wherein, when the friction shoulder approaches the joining zone, the plastic material is rubbed into the joining zone and mixed with the fiber-reinforced thermoplastic parts.
