Title (EN) NON-DESTRUCTIVE METHOD FOR DETECTING DEFECTS IN UNIDIRECTIONAL COMPOSITE INTERMEDIATE
(FR) PROCÉDÉ NON DESTRUCTIF DE DÉTECTION D'IRRÉGULARITÉS DANS UN INTERMÉDIAIRE COMPOSITE UNIDIRECTIONNEL
Abstract:
(EN) A non-destructive method provided for characterising a component (12) comprising unidirectional continuous carbon fibres having a main x-y plane, the continuous fibres being oriented along the x-axis, the method comprising measuring broadband electromagnetic terahertz radiations in function of time using a plurality of time delay stage positions, the method allowing to retrieve a value of at least one parameter indicative of a carbon content of the component (12).
(FR) L'invention concerne un procédé non destructif permettant de caractériser un composant (12) comprenant des fibres de carbone continues unidirectionnelles ayant un plan x-y principal, les fibres continues étant orientées le long de l'axe x, le procédé consistant à mesurer des rayonnements térahertz électromagnétiques à large bande en fonction du temps à l'aide d'une pluralité de positions d'état de retard temporel, le procédé permettant de récupérer une valeur d'au moins un paramètre indiquant une teneur en carbone du composant (12).
