| Résumé : |
Two-step parametric models of braided structures can be used for the visualisation of braids for composites at the filament level. Such models allow quick preliminary checking of braids, identifying the required braiding machine and material, and performing the initial optimisation of the complete product. |

- Fig. 1. Steps in the parametric morletling of braided structures:. al commun modal based on circular cross section rovings, used in ihe metal cire or rope industries; 111 application of the mulet based on circular cross section rovings for the generation of the roving axes, the roving thickness being used as roving diarneter ; c) added single filaments swept aLong the roving axis
- Fig. 2. Definition of a complex roving configuration using multiple parallel filament layers
- Fig. 3. Simulated braids with 48 carriers, different floating lengths and 0° yarns (inlay) in some : a) raid with a floating length of 1, b) braid with a floating length of 2, the right part of the braid has inlay yarns, c) braid with a floating length of 3, d) braid with a floating length of 4
- Fig. 4. a) Configuration of the machine for the braid shown in fig. 3c, calculated from the program ; b) limitation of the pure geometrical, generalized algorithms - the filaments in dense structures can interlace |
