Advanced technical ceramics - Mechanical properties of ceramic composites at room temperature - Part 3: Determination of flexural strength

This part of EN 658 specifies the conditions for the determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement, under three-point or four-point bending at ambient temperature. This standard applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional xD with (2 < x <= 3), loaded along one principal axis of reinforcement.

Hochleistungskeramik - Mechanische Eigenschaften von keramischen Verbundwerkstoffen bei Raumtemperatur - Teil 3: Bestimmung der Biegefestigkeit

Dieser Teil von EN 658 legt ein Verfahren zur Bestimmung der Biegefestigkeit von endlosfaserverstärkten Verbundwerkstoffen mit keramischer Matrix bei Raumtemperatur mittels Drei-Punkt- oder Vier-Punkt-Biegung fest. Dieses Verfahren gilt für alle keramischen Verbundwerkstoffe mit unidirektionaler (1D), bidirektionaler (2D) und tridirektionaler xD mit (2 < x < 3) Endlosfaserverstärkung, wie in ENV 13233 festgelegt, die parallel zu einer der Hauptachsen der Faserverstärkung beansprucht werden.
ANMERKUNG   Das Prüfverfahren sollte nicht angewendet werden, um absolute Festigkeitskennwerte für Konstruktionszwecke zu ermitteln.

Céramiques techniques avancées - Propriétés mécaniques des céramiques composites à température ambiante - Détermination de la résistance en flexion

La présente partie de l'EN 658 décrit une méthode permettant de déterminer la résistance à la flexion des matériaux composites à matrice céramique et à renforts de fibres continus par un essai de flexion en trois points ou en quatre points à température ambiante. Cette méthode s'applique à tous les matériaux composites à matrice céramique à renforts de fibres continus, unidirectionnels (1D), renforcés dans le plan (2D) et multidirectionnels xD avec (2 < x   3), conformément à l'ENV 13233, sollicités suivant un axe principal de renfort.
NOTE   Il convient de ne pas utiliser la méthode pour obtenir des valeurs absolues de résistance à des fins conceptuelles.
