Fine ceramics (advanced ceramics, advanced technical ceramics) - Mechanical properties of ceramic composites at high temperature - Determination of compressive properties (ISO 14544:2025)
This document specifies procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at elevated temperature in air, vacuum and inert gas atmospheres. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bidirectional (2D) and multi-directional (xD, with x > 2), tested along one principal axis of reinforcement or off axis conditions for 2D and xD materials. This document also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C). Two cases of testing are distinguished: compression between platens and compression using grips.
Hochleistungskeramik-Mechanische Eigenschaften von keramischen Verbundwerkstoffen bei hoher Temperatur-Bestimmung der Eigenschaften unter Druck (ISO 14544:2025)
Dieses Dokument legt Verfahren zur Bestimmung des Druckverhaltens von endlosfaserverstärkten Verbundwerkstoffen mit keramischer Matrix bei erhöhter Lufttemperatur, im Vakuum und in Inertgasatmosphären fest. Dieses Dokument gilt für alle endlosfaserverstärkten Verbundwerkstoffe mit keramischer Matrix mit unidirektionaler (1D), bidirektionaler (2D) und mehrdirektionaler (xD, mit x > 2) Verstärkung mit der Beanspruchung längs zu einer der Hauptverstärkungsachsen oder bei 2D- und xD-Werkstoffen mit außeraxialer Beanspruchung. Dieses Dokument gilt auch für kohlenstofffaserverstärkte Verbundwerkstoffe mit Kohlenstoffmatrix (auch als Kohlenstoff/Kohlenstoff oder C/C bezeichnet). Es werden zwei Fälle von Prüfungen unterschieden: Druckbeanspruchung zwischen Platten und Druckbeanspruchung unter Verwendung von Einspanneinrichtungen.
Céramiques techniques - Propriétés mécaniques des composites à matrice céramique à haute température - Détermination des caractéristiques en compression (ISO 14544:2025)
Le présent document spécifie des modes opératoires permettant de déterminer le comportement en compression des matériaux composites à matrice céramique avec renfort de fibres continues, à haute température sous air, sous vide ou dans une atmosphère de gaz inerte. Le présent document s’applique à tous les composites à matrice céramique avec renfort de fibres continues, unidirectionnel (1D), bidirectionnel (2D) et multidirectionnel (xD, avec x > 2), sollicités suivant un axe principal de renfort ou dans des conditions hors axe pour les matériaux de type 2D et xD. Il s’applique également aux composites à matrice de carbone avec renfort de fibres de carbone (également connus en tant que carbone/carbone ou C/C). Deux cas de compression sont distingués: la compression entre plateaux et la compression entre mors.
