Title
(EN) AUTOMATED PLACEMENT OF PREPREG TAPES TO FORM COMPOSITE PARTS
(FR) PLACEMENT AUTOMATISÉ DE BANDES PRÉ-IMPRÉGNÉES POUR FORMER DES PIÈCES COMPOSITES
Abstract
(EN)
Prepreg tapes suitable for automated placement process are formed by slitting a sheet of partially impregnated prepreg. The partially impregnated prepreg (13) is composed of unidirectional fiber tows partially embedded in a resin layer and has a continuous resin surface only on one side. In some embodiments, one or two nonwoven veil(s) is/are incorporated into the partially impregnated prepreg.
(FR)
Selon l'invention, des bandes pré-imprégnées appropriées pour un procédé de placement automatisé sont formées par découpe d'une feuille de préimprégné partiellement imprégné. Le préimprégné partiellement imprégné (13) est composé de câbles de fibres unidirectionnelles partiellement incorporés dans une couche de résine et présente une surface de résine continue uniquement sur un côté. Dans certains modes de réalisation, un ou deux voile(s) non tissé(s) est/sont incorporé(s) dans le préimprégné partiellement imprégné.
