Fine ceramics (advanced ceramics, advanced technical ceramics) - Mechanical properties of ceramic composites at high temperature - Determination of compressive properties (ISO/FDIS 14544:2024)

This document describes 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 method 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 method 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/FDIS 14544:2024)

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/FDIS 14544:2024)

L'ISO 14544:2013 spécifie les conditions de détermination des caractéristiques en compression des matériaux composites à matrice céramique et à renfort continu pour des températures allant jusqu'à 2 000 °C.
L'ISO 14544:2013 s'applique à tous les composites à matrice céramique à renfort continu, unidirectionnel (1D), bidirectionnel (2D), et tridirectionnel (xD, avec 2 < x ≤ 3) sollicités suivant un axe principal de renfort.
