StratifiésIndex. décimale : 668.4 Plastiques, vinyles Résumé : The development of automotive components is governed by many criteria related to energy, materials and cost issues, as well as environmental requirements. These complex problems lead to the need for reliable simulation technologies to improve forming prediction and optimize complex assembled lightweight components using fiber-reinforced thermoplastic materials. During the first step of the investigation described in this paper, the developed simulation approach is shown to be able to determinate the optimum blank geometry for the manufacturing of parts, which leads to the best match with the designed part geometry. Finally, the adopted simulation method has shown its ability to perform virtual optimization of composite components.

TubesIndex. décimale : 668.4 Plastiques, vinyles Résumé : In the Federal German Excellence Cluster "Merge", new processes for hydroforming-injection molding for processing thermoplastic fiber composites are being researched. With gas as a forming and supporting medium, fiber-reinforced plastic tubes have been processed for the first time. In specific applications, researchers succeeded in reducing the part weight and process costs, and increasing productivity. Note de contenu : - Hybrid high performance parts
- Hydroforming/Injection molding of FRP hollow profiles
- Optimization of the process chain for use of FRP hollow profiles
- FIGURES : 1. Process chains for manufacturing hybrid structures. The merger of metal, plastic and FRP-specific processes pursues the goal of combining the individual manufacturing steps with one another appropriate to the component - 2. Combining hydroforming and injection molding in situ eliminates certain process steps. Forming, primary shaping and assembly take place in one mold - 3. Hybrid parts of complex formed metal hollow profiles and functional injection molded components are used in car models as cockpit crossmembers, front-end carriers and front-end adapters - 4.
