| Résumé : |
In large-scale automotive production, all-metal components are still mainly used instead of high-performance plastic/metal hybrids for reasons of cost. With a newly developed production process combining metal sheet forming and compression molding, hybrid components can now be manufactured more quickly and economically. |
| Note de contenu : |
- Efficient production of hybrid components
- Tool technology and sealing concept
- Design of hybrid components
- Production of the longitudinal and transverse control arms
- Figure : The longitudinal control arm or a rear suspension system made from a hybrid comprising long fiber-reinforced PA6 and steel sheet is formed an dbonded in one step. The two materials combine lightweight design with fail-safe crash behavior
- Fig. 1 : The subsequent process oprations shown schematically in a sectio nthrough a hybrid compression mold
- Fig. 2 : To prevent escape of thermoplastic melt in hybrid compression molding, various sealing concepts were developed for the mold. Sealing profiles with open ends, such as for side or cross members, posed a particular challenge
- Fig. 3 : Comparison and results of different component variants based on cross-member geometry in the three-point bending test. Weighing 10 % less than conventional steel strike plate structures (black), the steel/LFT (orange) structure can withstand twice the load
- Fig. 4 : Thanks to the component-optimized design of the suspension link, a thinner metal sheet could be used in combination with the plastic, so achieving an overall weight saving of around 20% compared with the steel reference component
- Fig. 5 : View of the D-LFT machine that precedes hybrid forming and view into the hybrid mold at Weber Fibertech. One-step production of the steel/LFT longitudinal control arm follows in a hydraulic upper ram press
- Fig. 6 : The finished hybrid control arm components before (transverse control arm) and after (longitudinal control arm) the trimming operation |
