PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Tape laying - The first processes for manufacturing of thermoplastic composite components with organic sheets have reached the series production stage. Further developments are now focused on solutions for thermoplastic tapes reinforced with glass and carbon fibers. Engel – the injection molding machine maker and systems supplier – also gathered the necessary experience in the manufacture of own products. For example, some of their own robots series are fitted with a lightweight carbon rotational axis. Heart of the production line is a tape laying cell that is based on the pick-and-place principle. |

- Carbon tapes for rotational axis
- Load-optimized component design
- Precise laying operation without matrix channels
- Optical measurement technology for high precision
- FIGURES : 1. The number of laying operations for producing a tape layup (tape:PA-CF ; thickness : 0.14 mm ; density : 146g/cm3) can be estimated by means of component weight, the proportion of tape, and the tape format - 2. Instead of conventional x-axis, type e-pic robots have a rotational axis, which also ensures that the system requires minimum space - 3. The rotational axis was designed with an assembled profile of carbon tapes and a stub of die-cast aluminum for connecting to the servo motor - 4. The load-optimized design of the rotational axis is based on FEM calculations - 5. The integrated process for manufacturing rotational axes with carbon tapes involves six working steps - 6.
