Advanced technical ceramics - Mechanical properties of ceramic composites at room temperature - Part 2: Determination of compression properties
This part of EN 658 specifies the conditions for determination of compression properties of ceramic matrix composite materials with continuous fibre reinforcement 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. Two cases are distinguished: - compression between platens; - compression using grips.
Hochleistungskeramik - Mechanische Eigenschaften von keramischen Verbundwerkstoffen bei Raumtemperatur - Teil 2: Bestimmung der Eigenschaften unter Druck
In diesem Teil von EN 658 sind die Bedingungen zur Bestimmung der Eigenschaften unter Druck von endlosfaserverstärkten Verbundwerkstoffen mit keramischer Matrix bei Raumtemperatur festgelegt, bidirektionaler (2D) und mehrdirektionaler (xD, mit 2 < x <3) Faserverstärkung, die parallel zu einer der Hauptverstärkungsachsen beansprucht werden. Man unterscheidet zwei Fälle: - Druckbeanspruchung zwischen Platten; - Druckbeanspruchung unter Verwendung von Einspannvorrichtungen.
Céramiques techniques avancées - Propriétés mécaniques des céramiques composites à température ambiante - Partie 2: Détermination des propriétés en compression
La présente partie de cette Norme européenne décrit une méthode permettant de déterminer les propriétés en compression des matériaux composites à matrice céramique et à renfort fibreux continu à la température ambiante. Cette méthode s'applique à tous les composites à matrice céramique à renfort fibreux continu, unidirectionnel (1D), bidirectionnels (2D) et tridirectionnels (xD, avec 2 < x 3), conformément à l'ENV 13233, sollicités suivant un axe principal de renfort.
On distingue deux cas :
compression entre plateaux ;
compression utilisant des mors de serrage.

The maximum percent bending shall not exceed 5 at an average strain of 610500-×.There are two alternative means of load application:a) compression platens are connected to
the load cell and on the moving cross head. The parallelism of theseplatens shall be better than 0,01 mm, in the loading area and they shall be perpendicular to the load direction.NOTE 1The use of platens is not recommended for compression testing of 1D and 2D materials with low thicknessesbecause of buckling.NOTE 2A compliant interlayer material between the test specimen and platens can be used for testing macroscopicallyinhomogeneous materials t
