Abstract

Dispositif de maintien en compaction d’une texture fibreuse pour la caractérisation de matériaux composites Un dispositif de maintien (100) d’un effort de compaction sur une texture fibreuse comprend des premier et deuxième éléments de compaction (110, 120) en regard l’un de l’autre. Les premier et deuxième éléments de compaction sont mobiles l’un par rapport à l’autre de manière à définir entre eux un logement à hauteur variable pour une texture fibreuse (10). Le dispositif de maintien comprend en outre des organes de serrage (150, 152, 153, 154, 156, 157) aptes à maintenir les premier et deuxième éléments de compaction (110, 120) à une distance déterminée (Dc) l’un de l’autre correspondant à un effort de compaction déterminé (PC) sur la texture fibreuse. Chacun des premier et deuxième éléments de compaction présente un taux de transmittance des rayons supérieur ou égal à 20%. Figure pour l’abrégé : Fig. 2.
