Advanced technical ceramics - Mechanical properties of ceramic composites at high temperature under inert atmosphere - Determination of flexural strength
This European Standard specifies the conditions for determination of the flexural strength of ceramic matrix
composite materials with continuous fibre reinforcement under three-point or four-point bending for
temperatures up to 2 000 °C under vacuum or a gas atmosphere which is inert to the material under test.
NOTE 1 The use of these environments is aimed at avoiding changes of the material affecting its flexural strength
caused by chemical reaction with its environment during the test.
This European document 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.
NOTE 2 The method outlined in this document should not be used to obtain values of flexural strength for design
purposes.
Diese Europäische Norm legt die Bedingungen für die Bestimmung der Biegefestigkeit von keramischen Verbundwerkstoffen mit Endlosfaserverstärkung unter Drei-Punkt- oder Vier-Punkt-Biegung bei Temperaturen bis zu 2 000 °C unter Vakuum oder an einer Gasatmosphäre, die gegenüber dem zu prüfenden Werkstoff inert ist, fest.
