| Résumé : |
A recently developed variant for processing continuous fiber-reinforced semi-finished products by injection molding, involves positioning a defined number of UD laminates appropriate to the specific requirements in the mold and then overmolding them. The resultant lightweight, three-dimensional parts have rigidity and strength which are markedly anisotropic and optimized for their particular loading situations. |

- Taking material savings to the max
- Demonstrator component reveals application potential
- Heated UD laminates pose engineering challenges
- Manufacturing skills combine to obtain molding
- Tested and found suitable for mass production
- FIGURES : 1. Demonstrator component with three UD laminate inlays of different dimensions. In the demonstrated cross-section (bottom) the inlays are colored in green - 2. For Transferring the laminates into the mold, KraussMaffei developed a specially optimized gripper system and also integrated - 3. Using the production cell completely installed by KraussMaffei, the demonstrator part could be manufactured with a cycle time of under 60s - 4. GKTool designed and built the mold for manufacturing the dmonstrator part and punch and matrix - 5. The results from the filing simulation match well with the filling study performed - 6. Depending on how the cavity fills with melt, the clamping elements can be separately retracted - 7. The comparison between simulation and the 4-point bending reveals a good match and thus the high quality of both the calculation and the component produced. The failure point under tensile (laminate on the underside) and compressive loading (laminate on the top side) is marked in red in each case
