Abstract
Procédé permettant la détermination non destructrice en ligne de la résistance d'adhésion interne de produits en panneaux composites. Le procédé consiste à envoyer une impulsion d'ultrason contre le panneau au moyen d'un premier transducteur, et à recevoir une impulsion transmise à un second transducteur. L'intensité du signal reçu, la température et l'épaisseur du panneau sont entrées dans un algorithme à partir duquel l'assemblage interne peut être calculé. Le transducteur récepteur est de préférence situé sur le côté opposé du panneau, et légèrement décalé par rapport au premier transducteur. L'inclusion de la température et de l'épaisseur du panneau comme variables indépendantes améliore considérablement la précision par rapport à celle fournie par les tests ultrasoniques non corrigés.
