Résumé : |
In addition to excellent mechanical characteristics and suitability for recycling, the key feature of hybrid lightweight structures made of fiber-reinforced thermoplastics is that automated, large series production is possible. New mold and process technologies were successfully developed within the scope of the ReLei research project, enabling the production of complex shaped sandwich elements in an efficient combined process. |

- The newly developed foam forming technology
- Process-oriented component design
- Special tool and automation technology solutions
- Composite sheets are transferred on both sides of the mold
- Forming by injection pressure
- Fig. 1 : The newly developed foam forming technology combines thermoplastic foam injection molding with thermoforming of fiber-reinforced thermoplastics in one process
- Fig. 2 : The ReLei technology demonstrator is defined by its complex structure
- Fig. 3 : The handling system - here in the open state - transfers the composite layers from the heating device to the injection mold
- Fig. 4 : Process sequence in the mold during production of the technology demonstrator: a) insertion of the heated, partly stacked pre-cut composite sheets, b) injection of the plastic melt, c) local expansion stroke, d) component ejection
- Fig. 5 : Special tool functionality : a) ejector side of the demonstrator mold, b) detail of the expansion zones, c) detail of vacuum exhausters |
