A NOVEL PROCESS FOR HYBRID STRUCTURAL PARTS

摘要

Hybrid structure technology comes into a new age through the use of adhesion promoters for metal-plastic combinations. Crosslinkable copolyamides used as a binder between metals and overmolded engineering plastics provide material engagement beyond the traditional mechanical interlocking of state of the art hybrid parts. This new manufacturing technology allows totally new designs for parts like front end modules, crosscar beams, or structural parts of the car body in combination with reduced material consumption due to higher stiffness. In many cases, optimized designs achieve nearly 20% weight reduction with a neutral cost impact.
