Media-tight Hybrid Composites for Fluid-bearing Housing Structures
- 152 Downloads
The use of lightweight plastic-metal-hybrids is interesting for hybrid lightweight construction of fluid-carrying cases, for example in powertrain components. However, the tightness of the plastic-metal compounds varies depending on the aging treatment. Scientists at the Open Hybrid Lab Factory and Volkswagen show how the material classes can be bonded in a media-tight manner with joint strength.
Process Requirements for Plastic Metal Hybrids
Hybrid composites of metals and plastics combine the material advantages of different material classes and thus provide efficient lightweight solutions for the automotive industry. In general, a metallic material is partially substituted by a fiber-reinforced plastic. In the developed plastic-metal compound, the different materials are materially bonded. It is also possible to combine bonding mechanisms, for example by using bonding agents or micro/macro form-locking. Depending on component requirement this results in challenging development of...
