Aerospace series - Carbon fibre laminates - Determination of the fibre, resin and void contents

This European Standard specifies the methods for determining the fibre content by volume and mass and, by correlation, the resin content by volume and mass and void content by volume, of carbon fibre laminates, for aerospace applications.

Luft- und Raumfahrt - Kohlenstofffaser-Laminate - Bestimmung der Faser-, Harz- und Porenanteile

Diese Europäische Norm legt die Verfahren zur Bestimmung des Faseranteils nach Volumen und Masse und, in Wechselbeziehung dazu, des Harzanteils nach Volumen und Masse und des Porenanteils nach Volumen von Kohlenstofffaser-Laminaten für Anwendungen in der Luft- und Raumfahrt fest.

Série aérospatiale - Stratifiés de fibres de carbone - Détermination de la teneur en fibres, en résine et du taux de porosité

La présente Norme Européenne spécifie les méthodes de détermination de la teneur volumique et massique en fibres, et par corrélation, de la teneur volumique et massique en résine et du taux volumique de porosité des stratifiés de carbone polymérisés pour applications aérospatiales.

Aeronavtika - Laminati iz ogljikovih vlaken - Ugotavljanje deleža vlaken, smole in poroznosti

Ta evropski standard določa metode za ugotavljanje deleža vlaken (glede na prostornino in maso) ter v soodvisnosti od tega tudi deleža smole (glede na prostornino in maso) in poroznosti (glede na prostornino) pri laminatih iz ogljikovih vlaken, ki se uporabljajo v aeronavtiki.
