Abstract
(EN)
A method comprises forming a composite layup (642), including dispensing fiber material (101, 201); and monitoring the dispensed material prior to laydown for a marker (204, 302, 304, 306, 308, 310, 354). The marker (204, 302, 304, 306, 308, 310, 354) provides information about an upstream location of the material (101, 201). The forming further includes using the information in the marker (204, 302, 304, 306, 308, 310, 354) to adjust material course length to control where the upstream location will be deposited, if at all.
(FR)
La présente invention concerne un procédé qui comprend la formation d'un imprégné composite (642), contenant la distribution de matériau de fibre (101, 201) ; et la surveillance du matériau distribué avant la pose d'un marqueur (204, 302, 304, 306, 308, 310, 354). Le marqueur (204, 302, 304, 306, 308, 310, 354) fournit des informations à propos d'un emplacement en amont du matériau (101, 201). La formation comprend en outre l'utilisation des informations dans le marqueur (204, 302, 304, 306, 308, 310, 354) afin d'ajuster la longueur de course du matériau, pour commander l'endroit où l'emplacement en amont sera déposé, le cas échéant.
