Title
(EN) HYBRID FIBER MULTI-AXIAL PREPREG
(FR) PRÉ-IMPRÉGNÉ MULTIAXIAL DE FIBRES HYBRIDES
Abstract
(EN)
Multi-ply, hybrid composite materials useful in the formation of thin walled, hollow, tubular articles having improved resistance to hoop stress. Two different, single-ply pre-pregs are impregnated with binders and laminated together with the fibers of the layers oriented at a bias relative to each other. The hybrid composite is rolled into a tubular article having excellent strength uniformity along the full length of the tubular article.
(FR)
L'invention concerne des matériaux composites hybrides multicouches utiles dans la formation d'articles tubulaires creux à paroi mince présentant une résistance améliorée à la contrainte circonférentielle. Deux pré-imprégnés différents à une seule couche sont imprégnés de liants et stratifiés ensemble avec les fibres des couches orientées avec une polarisation l'une par rapport à l'autre. Le composite hybride est enroulé en un article tubulaire ayant une excellente uniformité de résistance sur toute la longueur de l'article tubulaire.
