Composite part

The invention relates to a composite part which is produced using two-component processing methods, preferably two-component injection-moulding (2C injection moulding), from at least one section consisting of at least one polyamide moulding compound that has polyalkenamer additives and at least one section consisting of at least one elastomer which can be obtained from rubber to be vulcanised or cross-linked with elementary sulphur, or said composite part being composed of said components after the production thereof, without any adhesion promoter being used. The individual sections of said composite part are macroscopic moulded parts although not, for example, dispersed particles in a plastic elastomer blend or polyamide fibres in an elastomer matrix, such blends therefore not constituting composite parts within the sense of the invention. The invention also relates to a method for producing such composite parts, to the use of polyalkenamer for improving the composite adhesion of polyamide-based moulded parts to an elastomer component which can be obtained from rubber to be vulcanised or cross-linked with elementary sulphur, and to the use of polyalkenamer for reducing the melting point or softening point of polyamide.
