Abstract
A connection element includes a composite component with a cured epoxy resin, a first layer including a first thermoplastic polymer and an intermediate layer arranged between the composite component and the first layer, the first layer containing both the cured epoxy resin of the composite component and the first thermoplastic polymer of the first layer. The first thermoplastic polymer has a melting point above a curing temperature of the epoxy resin and is soluble at a temperature of at least 150° C. in the epoxy resin used for producing the composite component.
