| Résumé : |
The range of applications of reinforced thermoplastics is growing, and there is a need to optimize the manufacturing process for these materials. This paper reports on a project conducted by Latecoere and the Czech Technical University in Prague to design and implement a quick process for manufacturing a T-profile with high mechanical performance in a required shape. The part was stamped in a sophoisticated tool, ensuring that the layers were positioned in a way that provides high strength. The stress analysis carried out by the finite element method (FEM) for a typical load was verified by mechanical testing. |
