Fine ceramics (advanced ceramics, advanced technical ceramics) - Mechanical properties of ceramic composites at room temperature - Determination of compressive properties (ISO 20504:2019)

This document describes procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bi-directional (2D) and tri-directional (xD, with 2 < x < 3), tested along one principal axis of reinforcement or off axis conditions. 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 Raumtemperatur - Bestimmung des Druckverhaltens (ISO 20504:2019)

Dieses Dokument beschreibt Verfahren zur Bestimmung der Eigenschaften unter Druck von endlosfaserverstärkten Verbundwerkstoffen mit keramischer Matrix bei Raumtemperatur. Dieses Verfahren ist anwendbar für alle keramischen Verbundwerkstoffe mit keramischer Matrix, die endlosfaserverstärkt sind, mit unidirektionaler (1D), bidirektionaler (2D) und mehrdirektionaler (xD, mit 2 < x < 3) Endlos¬faserverstärkung, die parallel zu einer der Hauptverstärkungsachsen oder außeraxial beansprucht werden. Dieses Verfahren gilt außerdem 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 Einspann¬einrichtungen.

Céramiques techniques - Propriétés mécaniques des composites à matrice céramiques à température ambiante - Méthode de détermination des propriétés en compression (ISO 20504:2019)

Le présent document décrit des procédures permettant de déterminer les caractéristiques en compression des matériaux composites à matrice céramique avec renfort de fibres continues à température ambiante. Il s'applique à tous les composites à matrice céramique avec renfort de fibres continues, unidirectionnel (1D), bidirectionnel (2D), et tridirectionnel (xD, avec 2 < x < 3), sollicités suivant un axe principal de renfort ou dans des conditions hors axe. Il peut également s'appliquer 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.

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Mehanske lastnosti keramičnih kompozitov pri sobni temperaturi - Določanje tlačnih lastnosti (ISO 20504:2019)

Ta dokument opisuje postopke za določanje vedenja keramičnih matričnih kompozitnih materialov z neprekinjeno ojačitvijo vlaken pri stiskanju pri sobni temperaturi. Ta metoda se uporablja za vse keramične matrične kompozite z neprekinjeno ojačitvijo vlaken, enosmerno (1D), dvosmerno (2D) in trismerno (xD, pri čemer je 2 < x ≤ 3), preskušene vzdolž ene glavne osi ojačitve ali v pogojih zunaj osi. Ta metoda se uporablja tudi za karbonske matrične kompozite s karbonskimi vlakni (imenovane tudi karbon/karbon ali C/C). Razlikujemo med dvema primeroma preskušanja: stiskanje med stiskalnimi valji in stiskanje z ročaji.
