| Résumé : |
Composite materials are often the key to lightweight design for many applications. However, these hybrid ‧materials face a major challenge where recycling is concerned. There is still no solution to the recovery of long and continuous fiber-reinforced materials. Where it is possible at all, only downcycling has been feasible until now. Four research partners have therefore set themselves the goal of developing a new press forming technology as part of a zero-waste project. |

- From the idea to the automotive component
- Fully automated process in the SMC manufacturing cell
- Figure : The experimental components were manufactured in a fully automated SMC manufacturing cell, developed by Engel, with and Engal v-duo 700 machine and an easix KR35 articulated robot
- Fig. 1 : The case study, a transmission cross¬member, illustrates the market potential of the zero-waste development.The C-SMC component (illustrated) weighs only half as much as the aluminum version
- Fig. 2 : The tests were performed with different materials. The reference material was HexMC-i 2000, a commercially available carbon-SMC type
- Fig. 3 : In the optimized C-SMC press forming, the actual pressing of the material is performed following an approx. 15 s compression phase
- Fig. 4 : The zero-waste sandwich structure was locally reinforced with a UD tape For the fastening points, aluminum inserts were introduced into the mold
- Fig. 5 : The structural components were mechanically tested on a servo-hydraulic test machine according to the OEM's specifications. Z was declared as critical load direction
- Table 1 : The comparison of material and technology between die-cast aluminum and carbon SMC confirms the success of the zero-waste concept |
